FLUID COSMETIC COMPOSITIONS WITH UNUSUAL RHEOLOGIC CHARACTERISTICS, POLYMERS ADAPTED TO PROVIDE THE ABOVE SAID CHARACTERISTICS AND THEIR SYNTHESIS

Document Type and Number:

WIPO Patent Application WO/2022/249046

Kind Code:

A3

Abstract:

A fluid cosmetic composition with unusual rheologic characteristics has a formulation comprising 0.1 to 50% by weight of at least one fluid branched polymer obtained by simultaneous reaction from components A, B and C, where A is a linear polymer with a molecular weight MW between 5000 and 50000 Da, provided with reactive functional groups X in a chain at a concentration between 0.1 and 50 mmol/g of polymer, B is a linear polymer with a molecular weight MW between 10000 and 100000 Da, having terminal reactive functional groups of type Y capable of reacting with the functional group X in an addition or condensation reaction, and C is a molecule or linear oligomer (or a mixture thereof) with a molecular weight between 50 and 1000 Da, having a reactive functional group Y per molecule, capable of reacting with the functional group X in an addition or condensation reaction. The molar ratio of the functional groups of B and A is between 0.01 and 0.5 and the molar ratio of the functional groups of C and A is between 0.5 and 1.2. The reactive group X of A is capable of reacting with the reactive sites Y of B and C.
