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 mono- or di-alkylamino alkyl(meth)acrylate, wherein the alkyl group has 1 to 4 carbon atoms; and(iii) 0.01 to 30 weight percent of an associative monomer selected from the group consisting of (b) an ethylenically unsaturated copolymerizable surfactant monomer obtained by condensing a noniomc surfactant with an ethylenically unsaturated carboxylic acid or the anhydride thereof;wherein the weight percent of monomers is based on 100 weight percent.
