[0001] This application claims benefit of US Provisional Patent Application No. 63/381,953 filed on November 2, 2022 and US Provisional Patent Application No. 63/505,849 filed on June 2, 2023, the entire contents/disclosures of which are incorporated herein by reference.

TECHNICAL FIELD

[0002] The present disclosure generally relates to the field of cleaning products, and more particularly to a method and apparatus for making plastics-free dissolvable cleaning products which can take any shape or form.

BACKGROUND

[0003] The majority of conventional cleaning products come in as a liquid in a vessel with a dispenser or in packs/pods that are wrapped in polyvinyl alcohol (PVA) and/or other types of plastic. These vessels are mostly made up of plastic, glass, PVA, and/or cardboard lined with plastic to serve as a water barrier. However, single use plastic is wreaking havoc on the environment. Only a small percentage of all plastic is actually recycled, and packaging generates the largest portion of municipal waste. Packaged products are inefficient for businesses and the people who buy them.

[0004] Due to changes in customer buying behavior, and a focus on sustainability, cleaning products having a reduced package size and do not contain plastics are becoming more and more preferred. Thus, a need exists for new stable formulations of cleaning products that meet the needs of consumers, while also reducing the amount of waste, such as plastics, generated in their production and shipping.

SUMMARY

[0005] Methods, systems, and apparatuses for forming dissolvable cleaning products. In an example, the dissolvable cleaning products may be formed by adding water and a methylcellulose based thickener to a first mixer. A water soluble polymer and a nonionic surfactant may be added to a second mixer. One or more thickeners and one or more additional ingredients may be added to the second mixer. The water and methylcellulose based thickener mixture may be transferred from the first mixer to the second mixer to form a final mixture. The final mixture may be chilled to a cooled temperature range.

[0006] In an example, the chilled final mixture may be transferred to an extruder, wherein the cooled temperature range is maintained during and after the transfer, and extruded through a die to form one or more extruded portions. In an example, the one or more portions may be cut and/or scored. The cut and/or scored extruded portions may be cured at the cooled temperature range to form the dissolvable cleaning products. In another example, the final solution may be dispensed into one or more molds. The one or more molds may be cured at the cooled temperature range to form the dissolvable cleaning products.

[0007] In another example, the dissolvable cleaning products may be formed by adding water and a methylcellulose based thickener to a first mixer to form a slurry. The slurry may be transferred to a second mixer. A water soluble polymer, a nonionic surfactant, and one or more thickeners may be added to the slurry in the second mixer. One or more additional ingredients may be added to the second mixer to form a final mixture. The final mixture may be chilled to a cooled temperature range.

[0008] In an example, the chilled final mixture may be transferred to an extruder, wherein the cooled temperature range is maintained during and after the transfer, and extruded through a die to form one or more extruded portions. In an example, the one or more portions may be cut and/or scored. The cut and/or scored extruded portions may be cured at the cooled temperature range to form the dissolvable cleaning products. In another example, the final solution may be dispensed into one or more molds. The one or more molds may be cured at the cooled temperature range to form the dissolvable cleaning products.

[0009] A dissolvable cleaning product that may have the following composition: approximately 1.02 wt% to approximately 1.54 wt% of a methylcellulose based thickener; approximately 10.24 wt% to approximately 15.36 wt% of a water soluble polymer; approximately 2.56 wt% to approximately 3.84 wt% of a nonionic surfactant; approximately 1.07 wt% to approximately 1.62 wt% of one or more thickeners; and approximately 54.67 wt% to approximately 82.00 wt% of one or more surfactants, one or more preservatives, and one or more enzymes. The dissolvable cleaning product may also include approximately 10.44 wt% to approximately 15.66 wt% of water. In an example, the dissolvable cleaning product may have a shape of a bar comprising a number of pieces that are configured to be broken off. In another example, the dissolvable cleaning product may have a shape of a tablet. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The detailed description set forth below is intended as a description of various implementations and is not intended to represent the only implementations in which the subject technology may be practiced. As those skilled in the art would realize, the described implementations may be modified in various different ways, all without departing from the scope of the present disclosure. Accordingly, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0026] Liquid and powder cleaning products are known and in the market. A problem with these known forms of un-premeasured cleaning products is that consumers are required to measure out appropriate amounts from containers, which often leads to consumers using too much, or too little. Furthermore, the process of measuring out the liquid or powder is inconvenient, and messy, often leading to accidental spills. Additionally, conventional, un-premeasured powders and liquids are bulky and can require large and awkward containers to deliver enough cleaning product in a single package, which increases the costs of shipping and storing the products through the supply chain. These large containers may also be hard for consumers to handle, store, and use, and may burden the environment as a result of their disposal as solid waste. Typical vessels are mostly made up of plastic, glass, PVA, and/or cardboard lined with plastic to serve as a water barrier. Even recyclable vessels must be collected and transported to recycling sites to be sorted into like materials and only a small percentage of plastics are recyclable.

[0027] Attempts to overcome the problems associated with the liquid and powder cleaning products have led to the development of products containing pre-measured amounts in single use dosage forms, such as dissolvable tablets pouches containing, for example, liquid detergent (and often other cleaning aids), and detergent sheets. These dissolvable cleaning products have a relatively small footprint, resulting in substantially lower shipping and storage costs throughout the supply chain. Their small physical dimensions also make dissolvable cleaning products eco-friendly since far less carbon is generated from fossil fuel energy spent in transporting them from their place of manufacture to the ultimate consumer, as compared to their bulkier liquid, powder, and pouch counterparts.

[0028] However, conventional dissolvable tablets and pouches are still typical made using plastics, such as PVA, to either encapsulate and/or bind the cleaning product in its single use form. This presents a problem as the plastics, once dissolved, can enter the water supply and wreak havoc on the environment. Microplastics are a big, and growing, part of global pollution. In oceans alone, annual plastic pollution, from all types of plastics, was estimated at 4 million to 14 million tons in the early 21 ^st century. Not only are microplastics harmful to ocean and aquatic life, but they are also showing up more and more in humans. These problems pose a threat on their own, but also create frustration in consumers who embrace the concept of reducing impact on the environment with waste including packaging and transportation and may lead to a slower adoption by the general public.

[0029] Accordingly, an improved method of forming dissolvable cleaning products without any type of plastics in either the formulation or the packaging is desired. The following description contains examples of methods, systems, and apparati that produce plastics-free dissolvable cleaning products that can be formed into any desirable shape. The advantages of these dissolvable cleaning products over conventional solid and liquid cleansers include chemical stability, reduced packaging, and convenience for the consumer. The dissolvable cleaning products and production methods may be used with a variety of concentrates, such as, without limitation, a bathroom cleaner, a multi-surface cleaner, a glass cleaner, a hand soap, a laundry detergent, or a dish soap. Examples of the dissolvable cleaning products are described below.

[0030] Referring now to FIG. 1A, a flowchart illustrating a method of forming a final mixture for a dissolvable cleaning product is shown. The dissolvable cleaning product may be prepared by mixing one or more ingredients under controlled temperatures, times, and mixing speeds to form a solution.

[0031] In step 102, water may be added to a first mixer. In an example, the water may range from approximately 21.52 wt% to approximately 32.28 wt% of total ingredients of a final mixture, as described below. In another example, the water may range from approximately 24.21 wt% to approximately 29.59 wt% of total ingredients of the final mixture. In another example, the water may be approximately 26.9 wt% of total ingredients of the final mixture.

[0032] The water may be purified water. The water may be added to the first mixer at room temperature. In an example, the first mixer may be a shearing mixer. The first mixer may be jacketed to allow for an increase and decrease in temperature within the mixing vessel. As an example, the first mixer may have a capacity of 2500 kg.

[0033] In step 104, a methylcellulose based thickener (e.g., METHOCEL™ A15C manufactured by DuPont) may be added to the water in the first mixer. In an example, the methylcellulose based thickener may range from approximately 0.86 wt%to approximately 1.29 wt% of total ingredients of the final mixture. In another example, the methylcellulose based thickener may range from approximately 0.97 wt% to approximately 1.18 wt% of total ingredients of the final mixture. In another example, the methylcellulose based thickener may range from approximately 0.05 wt% to approximately 1.50 wt% of total ingredients of the final mixture. In another example, the methylcellulose based thickener may be approximately 1.08 wt% of total ingredients of the final mixture.

[0034] The methylcellulose based thickener may be any type of methylcellulose conventionally used in the art. For example, the methylcellulose based thickener may be METHOCEL™ A15C manufactured by DuPont. The water and the methylcellulose based thickener may be mixed until smooth. The first mixer may be able to run at mixing speeds up to approximately 6000 rpm. In an example, the first mixer may start at approximately 500 rpm and as the viscosity increases, the speed may be increased to the maximum rpm.

[0035] In an example, a temperature of the first mixer may be controlled such that a temperature of the water and methylcellulose based thickener does not exceed approximately 45 °C in order to prevent gelling.

[0036] In step 106, a water soluble polymer and a nonionic surfactant may be added to a second mixer and mixed. In an example, the water soluble polymer may be glycerin. The nonionic surfactant may be any type of polysorbate used in the art, including Tween® 80 manufactured by Croda Americas, Inc.

[0037] In an example, the water soluble polymer may range from approximately 8.61 wt% to approximately 12.91 wt% of total ingredients of the final mixture. In another example, the water soluble polymer may range from approximately 9.68 wt% to approximately 11.83 wt% of total ingredients of the final mixture. In another example, the water soluble polymer may range from approximately 8.00 wt% to approximately 15.00 wt% of total ingredients of the final mixture. In another example, the water soluble polymer may be approximately 10.76 wt% of total ingredients of the final mixture.

[0038] In an example, the nonionic surfactant may range from approximately 2.15 wt% to approximately 3.23 wt% of total ingredients of the final mixture. In another example, the nonionic surfactant may range from approximately 2.42 wt% to approximately 2.96 wt% of total ingredients of the final mixture. In another example, the nonionic surfactant may range from approximately 1.0 wt% to approximately 5.0 wt% of total ingredients of the final mixture. In another example, the nonionic surfactant may be approximately 2.69 wt% of total ingredients of the final mixture.

[0039] As will be appreciated by persons skilled in the art, glycerin and water are commonly used to provide flexibility and elongation of polymers. However, while water evaporates, glycerin does not. The amount of glycerin may be increased to accommodate for various relative humidity conditions at the cleaning product manufacturing plant if relative humidity is not controlled. As will be appreciated, this consideration relates to glycerin-water hysteresis.

[0040] In an example, the second mixer may be a paddle mixer. The second mixer may be jacketed to allow for an increase and decrease in temperate within the mixing vessel. As an example, the second mixer may have a capacity of 2500 kg. In an example, the second mixer may contain one or more mixing paddles configured to reduce the incorporation of gas bubbles during mixing and may also rotate the paddles in a specific pattern configured to reduce bubble formation and incorporation.

[0041] The second mixer may be turned on and set to mix with a rotational speed in a range of approximately 40 rpm to approximately 220 rpm. The water soluble polymer/nonionic surfactant mixture may be mixed for approximately 5 mins at low speed at room temperature.

[0042] In step 108, one or more thickeners may be added to the second mixer. In an example, the one or more thickeners may include one or more of sodium polyacrylate and xanthan gum.

[0043] In an example, the sodium polyacrylate may range from approximately 0.86 wt% to approximately 1.29 wt% of total ingredients of the final mixture. In another example, the sodium polyacrylate may range from approximately 0.97 wt% to approximately 1.18 wt% of total ingredients of the final mixture. In another example, the sodium polyacrylate may range from approximately 1.00 wt% to approximately 5.00 wt% of total ingredients of the final mixture. In another example, the sodium polyacrylate may be approximately 1.08 wt% of total ingredients of the final mixture.

[0044] In an example, the xanthan gum may range from approximately 0.04 wt% to approximately 0.06 wt% of total ingredients of the final mixture. In another example, the xanthan gum may range from approximately 0.05 wt% to approximately 0.06 wt% of total ingredients of the final mixture. In another example, the xanthan gum may range from approximately 0.10 wt% to approximately 1.0 wt% of the total ingredients of the final mixture. In another example, the xanthan gum may be approximately 0.05 wt% of total ingredients of the final mixture.

[0045] The one or more thickeners may be added after the water soluble polymer and the nonionic surfactant are fully mixed as they should coat the sodium polyacrylate and prevent the sodium polyacrylate from swelling when combined with the water and methylcellulose based thickener mixture. The one or more thickeners may be mixed for approximately 10 mins at low speed at room temperature until the mixture is smooth.

[0046] In step 110, one or more additional ingredients may be added to the second mixer. The one or more ingredients may include one or more surfactants, one or more preservatives, and one or more enzymes. In an example, the one or more additional ingredients may also optionally include one or more fragrances, which may be non-toxic and non-irritating.

[0047] The one or more surfactants may include one or more detersive surfactants including anionic, cationic, non-ionic, zwitterionic and amphoteric surfactants as well as combinations thereof. The one or more surfactants may include a mixture of surfactants of the same or different type of surfactants, such as a mixture of 2, 3, 4, 5 or more surfactants of the same type or of different types of surfactants, selected from the group consisting of anionic, cationic, non-ionic and amphoteric surfactants. The one or more surfactants may include an anionic detersive surfactant.

[0048] The one or more preservatives may include, for example, one or more of sodium benzoate and similar salts. What is desirable is to provide a preservative which inhibits growth of microbes and fungi. It will be appreciated by persons skilled in the art that other preservatives may be used in combination such as potassium sorbate, or other weak acids. All such other preservatives are within the scope of the present disclosure. In an example, the sodium benzoate may range from approximately 0.22 wt% to approximately 0.32 wt% of total ingredients of the final mixture. In another example, the sodium benzoate may range from approximately 0.24 wt% to approximately 0.30 wt% of total ingredients of the final mixture. In another example, the sodium benzoate may range from approximately 0. 10 wt% to approximately 1.0 wt% of total ingredients of the final mixture. In another example, the sodium benzoate may be approximately 0.27 wt% of total ingredients of the final mixture. [0049] The one or more surfactants may include one or more of sodium citrate, sodium bicarbonate, and sodium carbonate (e.g., monohydrate). In an example, the sodium citrate may range from approximately 8.61 wt% to approximately 12.91 wt% of total ingredients of the final mixture. In another example, the sodium citrate may range from approximately 9.68 wt% to approximately 11.83 wt% of total ingredients of the final mixture. In another example, the sodium citrate may range from approximately 8.00 wt% to approximately 15.00 wt% of total ingredients of the final mixture. In another example, the sodium citrate may be approximately 10.76 wt% of the total ingredients of the final mixture.

[0050] In an example, the sodium bicarbonate may range from approximately 9.47 wt% to approximately 14.20 wt% of total ingredients of the final mixture. In another example, the sodium bicarbonate may range from approximately 10.65 wt% to approximately 13.02 wt% of total ingredients of the final mixture. In another example, the sodium bicarbonate may range from approximately 10.00 wt%to approximately 15.00 wt% of total ingredients of the final mixture. In another example, the sodium bicarbonate may be approximately 11.83 wt% of the total ingredients of the final mixture.

[0051] In an example, the sodium carbonate may range from approximately 25.82 wt% to approximately 38.73 wt% of total ingredients of the final mixture. In another example, the sodium carbonate may range from approximately 29.05 wt% to approximately 35.50 wt% of total ingredients of the final mixture. In another example, the sodium carbonate may range from approximately 25.00 wt% to approximately 40.00 wt% of total ingredients of the final mixture. In another example, the sodium carbonate may be approximately 32.28 wt% of the total ingredients of the final mixture.

[0052] The one or more enzymes may include, for example, one or more of amylase, protease, lipase, and cellulase. In an example, the enzymes may range from approximately 1.85 wt% to approximately 2.78 wt% of total ingredients of the final mixture. In another example, the enzymes may range from approximately 2.08 wt%to approximately 2.54 wt% of total ingredients of the final mixture. In another example, the enzymes may range from approximately 1.00 wt% to approximately 10.00 wt% of total ingredients of the final mixture. In another example, the enzymes may be approximately 2.31 wt% of the total ingredients of the final mixture.

[0053] The one or more fragrances may include, for example, one or more of extract. In an example, the extract may be organic. For example, the one or more fragrancies may include organic lemongrass extract. The organic lemongrass may be an essential oil and may be steam extracted from fresh grass and roots of a lemongrass plant. In another example, the one or more fragrances may include conventional fragrances that are typically used in applications such as soap, detergents, and personal care applications (e.g., lotion, shampoo, and liquid soap). For example, the one or more fragrances may include fresh linen, such as the Fresh Linen Fragrance Oil distributed by Bulk Apothecary.

[0054] In an example, the one or more fragrances may range from approximately 0.192 wt% to approximately 0.288 wt% of total ingredients of the final mixture. In another example, the one or more fragrances may range from approximately 0.216 wt% to approximately 0.264 wt% of total ingredients of the final mixture. In another example, the one or more fragrances may range from approximately . 100 wt% to approximately 5 wt% of total ingredients of the final mixture. In another example, the one or more fragrances may be approximately 0.24 wt% of the total ingredients of the final mixture.

[0055] The one or more additional ingredients may be mixed on high speed until the mixture is uniform.

[0056] In step 112, the water and methylcellulose based thickener mixture may be transferred from the first mixer to the second mixer and mixed at a high speed until smooth with no large lumps. At first, the mixture may be lumpy (e.g., like cottage cheese), but will thin out as it is mixed. The mixing may be conducted for approximately 30 mins. The mixture may be shear-thinning, which means if the mixture is being stirred, it will remain a thick liquid. The final mixture may have a consistency similar to cake batter with small undissolved grains and may feel gritty.

[0057] In step 114, the final mixture may be chilled. The final mixture may begin to solidify as it is chilled. In an example, the final mixture may be chilled by cooling the second mixer to a temperature range of approximately 4°C to approximately 6°C (i.e., a cooled temperature range). This may assist in the polymerization of the methylcellulose with the other ingredients. The chilling may occur within the second mixer or the final solution may be transferred to another vessel for chilling. In an example, the final mixture may be chilled at the cooled temperature range for approximately 24 hours before being processed further. In another example, the final mixture may be stored almost indefinitely at the cooled temperature range before being processed further.

[0058] Referring now to FIG. IB, a flowchart illustrating another example method of forming a final mixture for a dissolvable cleaning product is shown. The dissolvable cleaning product may be prepared by mixing one or more ingredients under controlled temperatures, times, and mixing speeds to form a solution.

[0059] In step 116, water may be added to a first mixer. In an example, the water may range from approximately 21.52 wt% to approximately 32.28 wt% of total ingredients of a final mixture, as described below. In another example, the water may range from approximately 24.21 wt% to approximately 29.59 wt% of total ingredients of the final mixture. In another example, the water may be approximately 26.9 wt% of total ingredients of the final mixture.

[0060] The water may be purified water. The water may be added to the first mixer at room temperature. In an example, the first mixer may be a shearing mixer. The first mixer may be jacketed to allow for an increase and decrease in temperature within the mixing vessel. As an example, the first mixer may have a capacity of 2500 kg.

[0061] In step 118, a methylcellulose based thickener (e.g., METHOCEL™ A15C manufactured by DuPont) may be added to the water in the first mixer to form a slurry. In an example, the methylcellulose based thickener may range from approximately 0.86 wt% to approximately 1.29 wt% of total ingredients of the final mixture. In another example, the methylcellulose based thickener may range from approximately 0.97 wt% to approximately 1.18 wt% of total ingredients of the final mixture. In another example, the methylcellulose based thickener may range from approximately 0.05 wt%to approximately 1.50 wt% of total ingredients of the final mixture. In another example, the methylcellulose based thickener may be approximately 1.08 wt% of total ingredients of the final mixture.

[0062] The methylcellulose based thickener may be any type of methylcellulose conventionally used in the art. For example, the methylcellulose based thickener may be METHOCEL™ A15C manufactured by DuPont. The water and the methylcellulose based thickener may be mixed until smooth. The first mixer may be able to run at mixing speeds up to approximately 6000 rpm. In an example, the first mixer may start at approximately 500 rpm and as the viscosity increases, the speed may be increased to the maximum rpm.

[0063] In an example, a temperature of the first mixer may be controlled such that a temperature of the water and methylcellulose based thickener does not exceed approximately 45 °C in order to prevent gelling.

[0064] In step 120, the slurry may be transferred to a second mixer. In an example, the second mixer may be a paddle mixer. The second mixer may be jacketed to allow for an increase and decrease in temperate within the mixing vessel. As an example, the second mixer may have a capacity of 2500 kg. In an example, the second mixer may contain one or more mixing paddles configured to reduce the incorporation of gas bubbles during mixing and may also rotate the paddles in a specific pattern configured to reduce bubble formation and incorporation. [0065] In step 122, a water soluble polymer, a nonionic surfactant, and one or more thickeners may be added to the slurry in the second mixer and mixed. In an example, the water soluble polymer may be glycerin.

[0066] In an example, the water soluble polymer may range from approximately 8.61 wt% to approximately 12.91 wt% of total ingredients of the final mixture. In another example, the water soluble polymer may range from approximately 9.68 wt% to approximately 11.83 wt% of total ingredients of the final mixture. In another example, the water soluble polymer may range from approximately 8.00 wt% to approximately 15.00 wt% of total ingredients of the final mixture. In another example, the water soluble polymer may be approximately 10.76 wt% of total ingredients of the final mixture.

[0067] As will be appreciated by persons skilled in the art, glycerin and water are commonly used to provide flexibility and elongation of polymers. However, while water evaporates, glycerin does not. The amount of glycerin may be increased to accommodate for various relative humidity conditions at the cleaning product manufacturing plant if relative humidity is not controlled. As will be appreciated, this consideration relates to glycerin-water hysteresis.

[0068] The nonionic surfactant may be any type of polysorbate used in the art, including Tween® 80 manufactured by Croda Americas, Inc. In an example, the nonionic surfactant may range from approximately 2.15 wt% to approximately 3.23 wt% of total ingredients of the final mixture. In another example, the nonionic surfactant may range from approximately 2.42 wt% to approximately 2.96 wt% of total ingredients of the final mixture. In another example, the nonionic surfactant may range from approximately 1.0 wt% to approximately 5.0 wt% of total ingredients of the final mixture. In another example, the nonionic surfactant may be approximately 2.69 wt% of total ingredients of the final mixture.

[0069] In an example, the one or more thickeners may include one or more of sodium polyacrylate and xanthan gum.

[0070] In an example, the sodium polyacrylate may range from approximately 0.86 wt% to approximately 1.29 wt% of total ingredients of the final mixture. In another example, the sodium polyacrylate may range from approximately 0.97 wt% to approximately 1.18 wt% of total ingredients of the final mixture. In another example, the sodium polyacrylate may range from approximately 1.00 wt% to approximately 5.00 wt% of total ingredients of the final mixture. In another example, the sodium polyacrylate may be approximately 1.08 wt% of total ingredients of the final mixture.

[0071] In an example, the xanthan gum may range from approximately 0.04 wt% to approximately 0.06 wt% of total ingredients of the final mixture. In another example, the xanthan gum may range from approximately 0.05 wt% to approximately 0.06 wt% of total ingredients of the final mixture. In another example, the xanthan gum may range from approximately 0.10 wt% to approximately 1.0 wt% of the total ingredients of the final mixture. In another example, the xanthan gum may be approximately 0.05 wt% of total ingredients of the final mixture.

[0072] The second mixer may set to mix with a rotational speed in a range of approximately 40 rpm to approximately 220 rpm. In an example, the water soluble polymer, one or more thickeners, and slurry may be mixed for approximately 5 mins at low speed at room temperature. In an example, the one or more thickeners may be added after the water soluble polymer and the nonionic surfactant are fully mixed as they should coat the sodium polyacrylate and prevent the sodium polyacrylate from swelling when combined with the water and methylcellulose based thickener mixture. The one or more thickeners may be mixed for approximately 10 mins at low speed at room temperature until the mixture is smooth.

[0073] In step 124, one or more additional ingredients may be added to the second mixer. The one or more ingredients may include one or more surfactants, one or more preservatives, and one or more enzymes. In an example, the one or more additional ingredients may also optionally include one or more fragrances, which may be non-toxic and non-irritating.

[0074] The one or more surfactants may include one or more detersive surfactants including anionic, cationic, non-ionic, zwitterionic and amphoteric surfactants as well as combinations thereof. The one or more surfactants may include a mixture of surfactants of the same or different type of surfactants, such as a mixture of 2, 3, 4, 5 or more surfactants of the same type or of different types of surfactants, selected from the group consisting of anionic, cationic, non-ionic and amphoteric surfactants. The one or more surfactants may include an anionic detersive surfactant.

[0075] The one or more preservatives may include, for example, one or more of sodium benzoate and similar salts. What is desirable is to provide a preservative which inhibits growth of microbes and fungi. It will be appreciated by persons skilled in the art that other preservatives may be used in combination such as potassium sorbate, or other weak acids. All such other preservatives are within the scope of the present disclosure. In an example, the sodium benzoate may range from approximately 0.22 wt% to approximately 0.32 wt% of total ingredients of the final mixture. In another example, the sodium benzoate may range from approximately 0.24 wt% to approximately 0.30 wt% of total ingredients of the final mixture. In another example, the sodium benzoate may range from approximately 0. 10 wt% to approximately 1.0 wt% of total ingredients of the final mixture.

[0080] The one or more fragrances may include, for example, one or more of extract. In an example, the extract may be organic. For example, the one or more fragrancies may include organic lemongrass extract. The organic lemongrass may be an essential oil and may be steam extracted from fresh grass and roots of a lemongrass plant. In another example, the one or more fragrances may include conventional fragrances that are typically used in applications such as soap, detergents, and personal care applications (e.g., lotion, shampoo, and liquid soap). For example, the one or more fragrances may include fresh linen, such as the Fresh Linen Fragrance Oil distributed by Bulk Apothecary.

[0081] In an example, the one or more fragrances may range from approximately 0.192 wt% to approximately 0.288 wt% of total ingredients of the final mixture. In another example, the one or more fragrances may range from approximately 0.216 wt% to approximately 0.264 wt% of total ingredients of the final mixture.

In another example, the one or more fragrances may be approximately 0.24 wt% of the total ingredients of the final mixture.

[0082] The one or more additional ingredients may be mixed on high speed until the mixture is uniform. At first, the mixture may be lumpy (e.g., like cottage cheese), but will thin out as it is mixed. The mixing may be conducted for approximately 30 mins. The mixture may be shear-thinning, which means if the mixture is being stirred, it will remain a thick liquid. The final mixture may have a consistency similar to cake batter with small undissolved grains and may feel gritty.

[0083] In step 126, the final mixture may be chilled. The final mixture may begin to solidify as it is chilled. In an example, the final mixture may be chilled by cooling the second mixer to a temperature range of approximately 4°C to approximately 6°C (i.e., a cooled temperature range). This may assist in the polymerization of the methylcellulose with the other ingredients. The chilling may occur within the second mixer or the final solution may be transferred to another vessel for chilling. In an example, the final mixture may be chilled at the cooled temperature range for approximately 24 hours before being processed further. In another example, the final mixture may be stored almost indefinitely at the cooled temperature range before being processed further.

[0088] Referring now to FIG. 2, a flowchart illustrating an example of a first extrusion process that may be used to form the dissolvable cleaning products from the chilled final mixture is shown. In step 202, the chilled final mixture may be transferred to an extruder, which may be hydraulic or electric. In an example, the chilled final mixture may be transferred directly to the extruder. For example, the chilled final mixture may be transferred directly to a feeding mechanism of the extrusion machine. In another example, the chilled final mixture may be transferred to a vessel (e.g., a temperature-controlled vessel) prior to be transferred to the extruder. In an example, the extruder may be at room temperature and the extrusion process may be carried out at room temperature. In another example, the chilled final mixture may be kept in the cooled temperature range at all points of the extrusion process. In this example, the extruder, which may be cooled, may include a cooled feeding mechanism to keep the chilled final mixture at the cooled temperature.

[0089] The extrusion of the chilled final mixture, which may not stick to components of the extruder and/or the conveyer belt, may reduce the energy input from the extrusion process. In either example, the chilled final mixture leaving the die of the extrusion machine may be very consistent and uniform.

[0090] In step 204, the chilled final mixture may pass though the extruder and may be applied onto a conveyor surface. As it exits the extruder, the final mixture may pass through a precisely shaped die such that it forms a layer on the conveyor surface in a desired shape and weight. The die may be of any desired shape and may include any desired number of openings. In an example, the die may include one or more openings to divide the final mixture into one or more portions, simultaneously, as it moves onto the conveyor.

[0091] In step 206, a cutting and/or scoring device may be placed after the die to cut and/or score the one or more portions of the extruded final mixture into dissolvable shapes having a precise size, shape, and weight as required. The cutting and/scoring process may use one or more of mechanical cutters (i.e. longitudinal cutters and transverse cutters), laser beams, waterjet cutters, etc., as will be appreciated by persons skilled in the art.

[0092] In step 208, the dissolvable shapes may be cured to form the dissolvable cleaning products. The curing step may be carried out at the cooled temperature range. The curing may be carried out for a suitable duration that allows to control the amount of residual moisture in the desired dissolvable shape. Suitable curing times will vary depending upon the conditions and composition of the final mixture and target final moisture content. In an example, the curing time may be approximately 12 hours to approximately 24 hours.

[0093] Referring now to FIGs. 3A-3B, top views of different examples of the dissolvable cleaning products formed from the first extrusion process are shown. In an example, the cutting and/or scoring process may produce a dissolvable cleaning product that is shaped like a bar 302 with any number of pieces (e.g., tablets) 304 that are scored out and may be broken off. In another example, the cutting and/or scoring process may produce a dissolvable cleaning product that is the individual pieces (e.g., tablets) 306 directly. Although FIG. 3A shows a bar 302 with ten pieces 304, any size and shape of bar 302 and any size, shape, and number of pieces 304 are contemplated. Similarly, even though FIG. 3B shows ten individual pieces 306, any size, shape, and number of individual pieces 306 are contemplated. Further, any size, shape, and number of dissolvable cleaning product (e.g., sheets, strips, blocks, geometric shapes) are contemplated.

[0094] Referring now to FIG. 4, a flowchart illustrating an example of a second extrusion process that may be used to form the dissolvable cleaning products from the chilled final mixture is shown. In step 402, the chilled final mixture may be transferred to an extruder, which may be hydraulic or electric. In an example, the chilled final mixture may be transferred directly to the extruder. For example, the chilled final mixture may be transferred directly to a feeding mechanism of the extrusion machine. In another example, the chilled final mixture may be transferred to a vessel (e.g., a temperature-controlled vessel) prior to be transferred to the extruder. In an example, the extruder may be at room temperature and the extrusion process may be carried out at room temperature. In another example, the chilled final mixture may be kept in the cooled temperature range at all points of the extrusion process. In this example, the extruder, which may be cooled, may include a cooled feeding mechanism to keep the chilled final mixture at the cooled temperature.

[0095] The extrusion of the chilled final mixture, which may not stick to components of the extruder and/or the conveyer belt, may reduce the energy input from the extrusion process. In either example, the chilled final mixture leaving the die of the extrusion machine may be very consistent and uniform.

[0096] In step 404, the chilled final mixture may pass though the extruder and may be distributed into one or more molds. As it exits the extruder, the final mixture may pass through a precisely shaped die such that it fills the one or more molds in a desired shape and weight. The die may be of any desired shape and may include any desired number of openings. In an example, the die may include one or more openings to divide the final mixture into one or more portions, simultaneously.

[0097] The molds may be of any desired shape to produce dissolvable cleaning products having a precise size, shape, and weight as required. In an example, the one or more molds may be approximately 5% larger than an intended size and shape of the dissolvable cleaning products to account for shrinkage during curing. In an example the one or more molds may be located on a conveyer belt that moves the one or more molds as they are being filled with the chilled final mixture.

[0098] In another example, the final solution from step 114 of FIG. 1A or step 126 of FIG. IB may be transferred directly to the one or more molds.

[0099] In step 406, the one or more molds may be cured to form the dissolvable cleaning products. The curing step may be carried out at the cooled temperature range. The curing may be carried out for a suitable duration that allows to control the amount of residual moisture in the desired dissolvable shape. Suitable curing times will vary depending upon the conditions and composition of the final mixture and target final moisture content. In an example, the curing time may be approximately 12 hours to approximately 24 hours. In step 408, the dissolvable cleaning products may be removed from the one or more molds.

[0119] It will be appreciated that the viscosity and density of the final mixture may control dimensions of the final mixture cleaning product shape applied to the conveyor surface upon exiting the chilled extruder, and ultimately the dimensions of the dissolvable cleaning products. If the viscosity of the final solution is too low, additional amounts of the one or more thickeners may be added to the mixture to increase the viscosity to the desired viscosity range. If the viscosity of the final mixture is too high, water may be added to the final mixture to reduce the viscosity to the desired viscosity range.

[0121] Additionally, these products can include those added to bottles and/or containers where it is best to apply as them as liquids. Products such as dish, handwashing, body, shampoos, auto, pets, pressure washers and any application where such a product is currently supplied in liquid bottles and/or containers, thereby reducing waste from such bottles and/or containers.

[0122] It will be appreciated by persons skilled in the art that it may be desirable to add fragrances, dyes, as well as other chemicals, such as for example, optical brighteners, enzymes, fabric softeners, bleaches, water softening agents, chelates, soil anti-redeposition agents, color-protecting agents, dye-transfer agents, known in the art, or later discovered, to impart expected characteristics or qualities to the resulting cleaning products.

In addition, the term “one or more” as used herein, depending at least in part upon context, may be used to describe any feature, structure, or characteristic in a singular sense or may be used to describe combinations of features, structures or characteristics in a plural sense. Similarly, terms, such as “a,” “an,” or “the,” again, may be understood to convey a singular usage or to convey a plural usage, depending at least in part upon context. In addition, the term “based on” may be understood as not necessarily intended to convey an exclusive set of factors and may, instead, allow for existence of additional factors not necessarily expressly described, again, depending at least in part on context.

In other words, functional elements being performed by single or multiple components, in various combinations of hardware and software or firmware, and individual functions, may be distributed among software applications at either the client level or server level or both. In this regard, any number of the features of the different examples described herein may be combined into single or multiple examples, and alternate examples having fewer than, or more than, all of the features described herein are possible. [0126] Functionality may also be, in whole or in part, distributed among multiple components, in manners now known or to become known. Thus, a myriad software/hardware/firmware combinations are possible in achieving the functions, features, interfaces and preferences described herein. Moreover, the scope of the present disclosure covers conventionally known manners for carrying out the described features and functions and interfaces, as well as those variations and modifications that may be made to the hardware or software or firmware components described herein as would be understood by those skilled in the art now and hereafter.
