Abstract:
A laundry treatment composition comprising a water-soluble or water-dispersible rebuild agent for deposition onto a fabric during a treatment process wherein the rebuild agent undergoes, during the treatment process, a chemical change by which change the affinity of the rebuild agent for the fabric is increased, said chemical change resulting in the loss or modification of one or more groups covalently bonded to be pendant to a polymeric backbone of the rebuild agent via an ester linkage, the ester-linkage group(s) being selected from one or more materials of general formula (I): wherein at least one or more R groups of the polymer are independently selected from groups of formulae: wherein each R2 is independently selected from hydrogen C1-20 alkyl, C2-20 alkenyl and C5-7 aryl; unsubstituted or substituted by one or more substituents independently selected from C1-4 alkyl, C1-12 alkoxy, hydroxyl, vinyl and phenyl groups; and n is an integer selected so that the weight average molecular weight of the rebuild agent is in the range of about 500 to 2Ã—106.
