Problems solved by technology

[0014] The inventors have discovered that while these prior art polymers are effective in preventing dye transfer when used to moderate dye transfer under typical conditions, they become ineffective and can even cause additional dye transfer under normal wash conditions in the presence of soil

Abstract

A detergent composition comprising a copolymer and at least one component selected from surface active agents and fabric softening compounds, the copolymer comprising at least one dye binding monomer and at least one anionic or nonionic monomer, with the proviso that the copolymer is not poly(1-vinylpyrrolidone-co-acrylic acid). Also a method of mitigating dye transfer in a detergent composition in the presence of typically encountered soils is provided. A dye binding copolymer comprising at least one anionic monomer selected from acrylic acid, methacrylic acid, vinyl sulphonic acid, itaconic acid, octanoic acid, hexanoic, hydroxy acetic acid or mixtures thereof or at least one nonionic monomer selected from polyethylene glycols and at least one dye binding monomer selected from vinyl imidazole, methyl vinyl imidazole, vinyl pyridine-N-oxide, vinyl pyrrolidone and mixtures thereof is also disclosed.

Description

field of invention [0001] The present invention relates to detergent compositions and methods for inhibiting dye transfer between fabrics during laundering. In particular, the present invention relates to detergent compositions containing novel dye transfer inhibiting copolymers. Background of the invention [0002] Colored fabrics tend to release dye into the wash solution during washing of the fabrics. These problems are the most persistent and troublesome because the released dyes can be transferred to other fabrics. Fabric treatment compositions comprising an agent which prevents dye transfer have therefore proven useful. [0003] EP 462 806 (Unilever) discloses a method for the domestic treatment of fabrics in which the level of dye released from the fabric is reduced with cationic dye fixing agents. Suitable cationic dye fixatives include dimethyl diallyl hexadienium chloride polymer. [0004] EP 0 587 550 (Procter and Gamble) discloses surfactant-containing dye tr...
