Patent ID: 6864223

Claim:
A fabric softening composition comprising: (a) from 0.01% to 35%, by weight, of a cationic softener wherein said cationic softener is an esterquat which is a biodegradable fatty ester quaternary ammonium compound having the formula: wherein R4 represents an aliphatic hydrocarbon group having from 8 to 22 carbon atoms, R 2 and R 3 represent (CH 2 ) s-R 5 where R 5 represents an alkoxy carbonyl group containing from 8 to 22 carbon atoms, benzyl, phenyl, (C1-C4)-alkyl substituted phenyl 1, OH or H; R1 represents (CH 2 ) t R 6 where R 6 represents benzyl, phenyl, (C1-C4)-alky substituted phenyl, OH or H; q, s, and t, each independently, represent an integer from 1 to 3; and X − is a softener compatible anion; (b) at least 0.00 1%, by weight, of a water soluble cross-linked cationic polymer derived from the polymerization of from 5 to 100 mole percent of cationic vinyl addition monomer, from 0 to 95 mole percent of acrylamide, and from 70 to 300 ppm of a difunctional vinyl addition monomer cross-linking agent; and (c) a perfume.
