Abstract
A free-flowing granular polymer composition suitable for incorporation into a particulate detergent composition comprises a defined dye-transfer-inhibiting polymer, preferably poly(4-vinylpyridine) sodium carboxymethyl betaine chloride, and a silica-based carrier material. A preferred carrier material is an acidic silica. The silica-based carrier material may optionally comprise a solid acid, for example, polyacrylic acid or phthalic acid.
Claims15
A free-flowing granular polymer composition suitable for incorporation in a particulate detergent composition, the granular polymer composition comprising
- (a) a dye-transfer-inhibiting polymer having the general formula I:
- wherein m indicates the degree of polymerisation, X is an anion, R1 and R2 are independently hydrogen, alkyl or aryl, n is an integer within the range of from 1 to 5, and M is a cation;
- (b) a carrier material comprising a silica.
