Claims
- 1-19. (canceled).
- 20. 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: 5 wherein R4 represents an aliphatic hydrocarbon group having from 8 to 22 carbon atoms, R2 and R3 represent (CH2)n—R5 where R5 represents an alkoxy carbonyl group containing from 8 to 22 carbon atoms, benzyl, phenyl, (C1-C4)-alkyl substituted phenyl, OH or H; R1 represents (CH2)tR6 where R6 represents benzyl, phenyl, (C1-C4)-alkyl 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 0.001%, by weight, of a water soluble cross-linked cationic polymer derived from the polymerization of from 5 to 100 mole percent of a 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.
- 21. The fabric softening composition of claim 20, wherein said cationic polymer is derived from said polymerization using 75 to 200 ppm of said cross-linking agent.
- 22. The fabric softening composition of claim 21, wherein said cationic polymer is derived from said polymerization using 80 to 150 ppm of said cross-linking agent.
- 23. The fabric softening composition of claim 20, wherein said cationic polymer is a cross-linked cationic vinyl polymer.
- 24. The fabric softening composition of claim 23, wherein said polymer comprises a quaternary ammonium salt of an acrylate or methacrylate.
- 25. The fabric softening composition of claim 24 wherein said polymer comprises a quaternary ammonium salt of dimethyl aminoethyl methacrylate.
- 26. The fabric softening composition of claim 20 further including a chelating compounds selected from the group consisting of amino carboxylic acid compounds, organo aminophosphonic acid compounds and mixtures thereof.
- 27. The fabric softening composition of claim 25 wherein said chelating compound comprises an amino carboxylic acid compound.
- 28. The fabric softening composition of claim 25 wherein said chelating compound comprises an organo aminophosphonic acid compound.
- 29. The fabric softening composition of claim 20 which further comprises a perfume.
