BACKGROUND OF THE INVENTION

Soil release polymers are known and used in fabric and home care formulations.

Method of Use. The compositions of this invention, prepared as hereinbefore described, can be used to form aqueous washing/treatment solutions for use in the laundering/treatment of fabrics. Generally, an effective amount of such compositions is added to water, for example in a conventional fabric automatic washing machine, to form such aqueous laundering solutions. The aqueous washing solution so formed is then contacted, typically under agitation, with the fabrics to be laundered/treated therewith. An effective amount of the liquid detergent compositions herein added to water to form aqueous laundering solutions can comprise amounts sufficient to form from about 500 to 7,000 ppm of composition in aqueous washing solution, or from about 1,000 to 3,000 ppm of the laundry care compositions herein will be provided in aqueous washing solution.

Typically, the wash liquor is formed by contacting the laundry care composition with wash water in such an amount so that the concentration of the laundry care composition in the wash liquor is from above 0g/l to 5g/l, or from lg/1, and to 4.5g/l, or to 4.0g/l, or to 3.5g/l, or to 3.0g/l, or to 2.5g/l, or even to 2.0g/l, or even to 1.5g/l. The method of laundering fabric or textile may be carried out in a top-loading or front-loading automatic washing machine or can be used in a handwash laundry application. In these applications, the wash liquor formed and concentration of laundry detergent composition in the wash liquor is that of the main wash cycle. Any input of water during any optional rinsing step(s) is not included when determining the volume of the wash liquor.

The wash liquor may comprise 40 liters or less of water, or 30 liters or less, or 20 liters or less, or 10 liters or less, or 8 liters or less, or even 6 liters or less of water. The wash liquor may comprise from above 0 to 15 liters, or from 2 liters, and to 12 liters, or even to 8 liters of water. Typically, from 0.01kg to 2kg of fabric per liter of wash liquor is dosed into said wash liquor.

Such compositions are typically employed at concentrations of from about 500 ppm to about 15,000 ppm in solution. When the wash solvent is water, the water temperature typically ranges from about 5 °C to about 90 °C and, when the situs comprises a fabric, the water to fabric ratio is typically from about 1 : 1 to about 30: 1. Typically the wash liquor comprising the laundry care composition of the invention has a pH of from 3 to 11.5.

In one aspect, such method comprises the steps of optionally washing and/or rinsing said surface or fabric, contacting said surface or fabric with any composition disclosed in this specification then optionally washing and/or rinsing said surface or fabric is disclosed, with an optional drying step.

Drying of such surfaces or fabrics may be accomplished by any one of the common means employed either in domestic or industrial settings. The fabric may comprise any fabric capable of being laundered in normal consumer or institutional use conditions, and the invention is suitable for cellulosic substrates and in some aspects also suitable for synthetic textiles such as polyester and nylon and for treatment of mixed fabrics and/or fibers comprising synthetic and cellulosic fabrics and/or fibers. As examples of synthetic fabrics are polyester, nylon, these may be present in mixtures with cellulosic fibers, for example, polycotton fabrics. The solution typically has a pH of from 7 to 11, more usually 8 to 10.5. The compositions are typically employed at concentrations from 500 ppm to 5,000 ppm in solution. The water temperatures typically range from about 5°C to about 90°C. The water to fabric ratio is typically from about 1 : 1 to about 30: 1. Another method includes contacting a nonwoven substrate, which is impregnated with the detergent composition, with a soiled material.

Non-limiting examples of suitable commercially available nonwoven substrates include those marketed under the trade names SONTARA® by DuPont and POLY WEB® by James River Corp.

Carbon source of raw materials:

The raw materials for preparation of the surfactant, polymers and other ingredients can be based on fossil carbon or renewable carbon. Renewable carbon is a carbon source that avoid the use of fossil carbon such as natural gas, coal, petroleum. Typically, renewable carbon is derived from the biomass, carbon capture, or chemical recycling.

Biomass is a renewable carbon source formed through photosynthesis in the presence of sunlight, or chemosynthesis process in the absence of sunlight. In some cases, polymers isolated from biomass can be used directly, or further derivatized to make performance polymers. For example, the use of polysaccharide (such as starch) and derivatized polysaccharide (such as cellulose derivatives, guar derivatives, dextran derivatives) in fabric home care composition are known. In some cases, biomass can be converted into basic chemicals under certain thermal, chemical, or biological conditions. For example, bioethanol can be derived from biomass such as straw, and further convert to biobased polyethylene glycol. Other nonlimiting examples of renewable carbon from biomass include plants (e.g., sugar cane, beets, corn, potatoes, citrus fruit, woody plants, lignocellulosics, hemicellulosics, cellulosic waste), animals, animal fats, fish, bacteria, fungi, plant-based oils, and forestry products. These resources can be naturally occurring, hybrids, or genetically engineered organisms.

Carbon capture is another renewable carbon source which use various process to capture CO2 or methane from industrial or natural processes, or directly from air (direct capture). Captured methane and CO2 maybe converted into syngas, and/or further convert to basic chemicals, including but not limit to methanol, ethanol, fatty alcohols such as C12/C14 or even Cie/Cis alcohols, other alcohols, olefins, alkanes, saturated and unsaturated organic acids, etc. These basic chemicals can used as or further convert to monomers for making transformed to usable chemicals by e.g. catalytic processes, such as the Fischer-Tropsch process or by fermentation by Ci -fixing microorganisms.

Chemical recycling is another renewable carbon source which allow plastics from waste management industry to be recycled and converted into base chemicals and chemical feedstocks. In some cases, waste plastics which cannot be re-used or mechanical recycled are convert to hydrocarbons or basic petrochemicals through gasification, pyrolysis or hydrothermal treatment processes, the hydrocarbons and basic petrochemicals can be further convert into monomers for polymers. In some cases, waste plastics are depolymerized into monomers to make new polymers. It is also possible that waste plastics are depolymerized into oligomers, the oligomers can be used as building blocks to make new polymers. The waste plastic converted by various processes to a waste plastic feedstock for the above materials may either be used alone or in combination with traditional surfactant feedstocks, such as kerosene, polyolefins derived from natural gas, coal, crude oil or even biomass, or waste fat/oil-derived paraffin and olefin, to produce biodegradable surfactants for use in detergents and other industries (thereby providing a benefit to society).

Preferably, the surfactant, polymers and other ingredients contains renewable carbon, the Renewable Carbon Index (RCI, a measure of sustainability by dividing the number of carbons derived from renewable sources by the total number of carbons in an active ingredient) of the polymer is above 10%, more preferably above 30%, more preferably above 50%, more preferably above 60%, more preferably between 70% to 100%, and most preferably 100%.

EXAMPLES

The examples below are intended to illustrate the invention in detail without, however, limiting it thereto. Unless explicitly stated otherwise, all percentages given are percentages by weight (% by wt. or wt.-%).

Polyester preparation

General procedure for the preparation of the polyesters of the examples:

The polyester synthesis is carried out by the reaction of dimethyl terephthalate (DMT), dimethyl- 5-sulfoisophthalate sodium salt (5-SIM), 1,2-propylene glycol, ethylene glycol, and alkyl capped polyalkylene glycol (mono hydroxyl-functional polyalkylene glycol monoalkyl ether), using sodium acetate (NaOAc) and tetraisopropyl orthotitanate (IPT) as the catalyst system. The synthesis is a two-step procedure. The first step is a trans-esterification and the second step is a polycondensation.

Key to reactants or ingredients used in the examples:

5-SIM is dimethyl-5-sulfoisophthalate sodium salt

AE NI is alkyl ethoxylate (EO)?

AES is alcohol ethoxysulfate

DMT is dimethyl terephthalate

EG is ethylene glycol

HEDP is 1 -hydroxy ethane- 1 , 1 -diphosphonic acid IPT is tetraisopropyl orthotitanate

LAS is linear alkyl benzene sulphonate

MGDA is methylglycine-diacetic acid mPEG3000 is mono hydroxyl-functional polyethylene glycol monomethyl ether, average molecular weight 3000 g/mol mPEG4000 is mono hydroxyl-functional polyethylene glycol monomethyl ether, average molecular weight 4000 g/mol

NaOAc is sodium acetate

PG is 1,2-propylene glycol

Inventive polyester example 1

58.26 g (0.30 mol) of dimethyl terephthalate (DMT), 29.63 g (0.10 mol) of dimethyl-5- sulfoisophthalate sodium salt (5-SIM), 28.04 g (0.373 mol) of 1,2-propylene glycol (PG), 24.19 g (0.39 mol) of ethylene glycol (EG), 210 g (0.07 mol) of mPEG3000 and 0.38 g of sodium acetate (NaOAc) (anhydrous) are weighed into a reaction vessel at room temperature. For the melting process and homogenization, the mixture is heated up to 110 - 120 °C. 134 pL of tetraisopropyl orthotitanate (IPT) is added and the mixture is further heated up to 210 °C over 3 hours sparged by a nitrogen stream. During the transesterification methanol is released from the reaction and is distilled out of the system. Once the head-temperature is below 55 °C, nitrogen is switched off and the pressure is reduced to 10 mbar. PG and EG are distilled out of the system. The mixture is stirred for further 4 hours at a pressure of 10 mbar. The reaction mixture is cooled down to 140 - 150 °C. Vacuum is released with nitrogen and the polyester is transferred out of the reactor.

Inventive polyester example 2

Inventive polyester example 2 is synthesized according to inventive polyester example 1 with monomer type and dosage described in Table 1.

Table 1 Monomer type and dosage for the preparation of inventive polyesters 1 and 2

The average amount of the monomers in a polyester is calculated as 1) a polyester has endcaps on both sides, 2) used DMT and 5-SIM are equally integrated into a polyester and 3) the excess amount of PG and EG are equally distilled out of the system.

Method of Testing Biodegradability of polyesters:

The biodegradability of polyesters is determined following the OECD 301B Ready Biodegradability CO2 Evolution Test Guideline. In this study, the test substance is the sole carbon and energy source and under aerobic conditions microorganisms metabolize the test substance producing CO2 or incorporating the carbon into biomass. The amount of CO2 produced by the test substance (corrected for the CO2 evolved by the blank inoculum) is expressed as a percentage of the theoretical amount of CO2 (ThCCE) that could have been produced if the organic carbon in the test substance was completely converted to CO2.

Method of Evaluating Whiteness Benefit of polyesters

During the laundry process, soil which has been removed from dirty clothes is suspended in the detergent solution. Some suspended soil can redeposit back onto clothes. Whiteness maintenance performance is the ability of a detergent to keep white items from whiteness loss when they are washed in the presence of soils.

The whiteness benefit of polyesters is evaluated using automatic Tergotometer with 10 pots for laundry formulation testing. SBL2004 test soil strips supplied by WFK Testgewebe GmbH are used to simulate consumer soil levels. On average, every 1 SBL2004 strip is loaded with 8g soil. The SBL2004 test soil strips were cut into 5x5 cm squares for use in the test. White Fabric swatches below from WFK Testgewebe GmbH are typically used as whiteness tracers. Codes for the used fabric are summarized in Table 2. Table 2 Codes for fabrics

Additional ballast (background fabric swatches) is also used to simulate a fabric load and provide mechanical energy during the real laundry process. Ballast loads are comprised of cotton and poly cotton knit swatches at 5/5 cm size.

4 cycles of wash are needed to complete the test:

Cycle 1 : Desired amount of detergent is fully dissolved by mixing with IL water (at defined hardness) in each tergotometer pot. 60 grams of fabrics, including whiteness tracers (4 types, each with 4 replicates), 31 pieces 5x5 cm SBL2004, and ballast are washed and rinsed in the tergotometer pot under defined conditions.

Cycle 2: The whiteness tracers and ballast from each pot are then washed and rinsed again together with a new set of SBL2004 (5 x5cm, 31 pieces) following the process of cycle 1. All other conditions remain the same as in cycle 1.

Cycle 3 : The whiteness tracers and ballast from each pot are then washed and rinsed again together with a new set of SBL2004 (5 x5cm, 31 pieces) following the process of cycle 1. All other conditions remain the same as in cycle 1.

Cycle 4: The whiteness tracers and ballast from each pot are then washed and rinsed again together with a new set of SBL2004 (5 x5cm, 31 pieces) following the process of cycle 1. All other conditions remain the same as in cycle 1.

After Cycle 4, all whiteness tracers & ballast are tumble dried between 60-65°C until dry, then the WI(CIE) of the dry tracers is measured using Konica Minolta CM-3610D spectrophotometer.

Method for Evaluating Soil Release Performance of polyesters

Soil release test were performed to assess how easy the stains can be removed from a fabric surface after the fabric surface has been modified by polyesters in previous washing cycles. Polyester (PE) fabrics from WFK Testgewebe GmbH were cut into 5 * 5 cm fabric swatches for the soil release test. 3 pieces of 5/5 cm fabric swatches were washed 4 cycles using detergent composition in an automatic tergotometer. After drying overnight under humidity and temperature control (50% RH, 20 ± 2 °C), 200 pl dirty motor oil (DM0) was applied onto each square of fabric swatches. After drying overnight, the DM0 soiled fabric swatches are then washed again using detergent compositions, together with knitted cotton ballast (total weight of ballast and DM0 soiled fabric swatches is 60g, in every IL pots of tergotometer). The washed polyester swatches are then dried overnight for image analysis.

Stain images were collected before and after washing against a white background with a reflection spectro-photometer (DigiEye). Images were analyzed using DigiEye software. For each fabric the color of the motor oil stains was evaluated by measuring the coordinates Ln*, an*, and bn* defined in the CIELAB colour system. From the measured coordinates the differences in lightness (ALn*), redness (Aan*), and blueness (Abn*) in contrast to the background were calculated. The relative color changes, AE*, were calculated comparing the coordinates variation before (n = 1) and after the wash (n = 2) by applying the following equations: and

Lastly, the stain removal index (SRI) was assessed as follows:
