Abstract:
A thickened aqueous fabric softener composition comprising at least one cationic surfactant and a polymeric rheology modifier, wherein said polymeric rheology modifier is the polymerization product of(i) 5 to 80 weight percent of an alkyl ester of acrylic acid or an alkyl ester of methacrylic acid, wherein the alkyl group has 1 to 18 carbon atoms; (ii) 5 to 80 weight percent of a monomer selected from the group consisting of a vinyl-substituted heterocyclic compound containing at least one nitrogen atom; and (iii) 0.01 to 30 weight percent of an associative monomer selected from the group consisting of a nonionic urethane monomer which is the urethane reaction product of a monohydric nonionic surfactant with a monoethylenically unsaturated isocyanate; wherein the weight percent of monomers is based on 100 weight percent.
