Abstract:
A method of promoting the release of oily soil from fabric, comprising contacting the fabric with at least one polymer of Formula 1: wherein:A is a polymerized residue of a monomer selected from one or more C3-C8 monoethylenically unsaturated carboxylic acids; B is a polymerized residue of a monomer selected from one or more ethoxylated C1-C24 alkyl (meth)acrylates, poly(alkylene glycol) (meth)acrylates, alkyl and the corresponding maleate mono and di-esters thereof; C is a polymerized residue of a monomer selected from one or more ethylenically unsaturated monomer which are copolymerisable with the monomers in A and B; A, B and C residues are randomly arranged in said polymer; S and T are end groups; m is the total number of A residues and is from 0 to 500; n is the total number of B residues and is >0; p is the total number of C residues and is from 0 to 500; the sum of m and p is at least 1; q is from 0 to 100; D is a C2-C4 alkylene oxide group; E is selected from C1-C50 alkyl groups and C6-C50 aromatic groups; X is a functional group; and wherein the polymer is applied to the fabric prior to soiling.
