The invention is based on the finding that a mixture of long and short chain DTI polymers gives improved removal of dyes from fabrics. It provides a fabric treatment composition which comprises one or more dye transfer inhibiting polymers, wherein the overall distribution of the molecular weight of said polymers is polymodal and whereby the composition is effective both at scavenging a dye from a fabric and at preventing redeposition of said dye. The present invention also extends to methods for treatment of fabrics which comprise treating the fabric with a composition according to the present invention. Preferred materials for the DTI polymer in either weight range include poly (ethylene glycol) (PEG), poly(vinyl pyridine carboxyl methyl betaine) (PVPCMB), poly(vinyl pyrrolidone) (PVP), N-oxide modified PVP (PVP-NO). |
