<p>A fabric conditioning composition comprising a substantially water insoluble cationic fabric softening agent and a copolymer characterised in that the copolymer comprises the following monomers: a) a negatively charged monomer having at least one carboxylate group and having the formula: R1R3C=CR2R4 wherein R1, R2, R3, and R4 are independently selected from H, or a C1-C4 alkyl group or a (CH2)nCOOR5 in which n is an integer between 1 and 6 or is 0 and R5 is H or a C1-C4 alkyl group, and at least one of R1, R2, R3 and R4 is a (CH2)nCOOR5 group, and b) a vinyl substituted heterocyclic monomer containing at least one nitrogen atom, and wherein the mole ratio of a):b) is in the range 20:80 to 50:50. Examples include, 70:30 Polyvinylimidazole/Acrylic acid copolymer. The fabric conditioning composition gives reduced dye transfer benefits. Use of the copolymer in a fabric conditioning composition as a dye transfer inhibiting copolymer in a fabric conditioning composition, wherein the copolymer does not cause de-stabilisation is also provided.</p> |
