Abstract
Fabric softening compositions comprising front-end stability agents exhibiting desirable viscosity profiles even when they contain polymeric delivery enhancing agents. Compositions comprising softening actives based on hardened tallow fatty acids are pumpable, pourable liquids and provide “low dose” fabric softeners for consumer use.
Claims25
A fabric care composition comprising:
- a) from about 1.5% to about 50% by weight of the composition of a fabric softening active;
- b) from about 0.5% to about 6% by weight of the fabric softening active of a front-end stability agent selected from saturated branched alcohols comprising 8 to about 20 carbon atoms, 2-hexyl-1-decanoic acid, the salts of said acid, and mixtures thereof;
- c) a delivery enhancing agent.
A fabric care composition comprising:
- a) from about 1.5% to about 50% by weight of the composition of a fabric softening active;
- b) from about 0.5% to about 6% by weight of the fabric softening active of a front-end stability agent selected from saturated branched alcohols comprising about 8 to about 20 carbon atoms or a member selected from the group consisting of saturated branched carboxylic acids comprising about 8 to about 20 carbon atoms, or the salts of said acids, and mixtures thereof;
- c) a delivery enhancing agent wherein said delivery enhancing agent is a cationic polymer having a weight-average molecular weight of from about 3000 to about 10,000,000 that comprises crosslinked poly(N-dimethyl amino ethyl methacrylate).
A composition comprising:
- a) from about 1.5% to about 50% by weight of the composition of a fabric softening active;
- that comprises a hydrogenated tallow-based cationic fabric softening active, comprising a dimethyl di-(hydrogenated tallowoyloxyethyl) ammonium salt;
- said hydrogenated tallow-based cationic fabric softening active, comprising a dimethyl di-(hydrogenated tallowoyloxyethyl) ammonium salt;
- said composition comprising greater than 15%, by weight of the composition, of hydrogenated DEEDMAC;
- b) from about 0.5% to about 4%, by weight of said softening active, of a stability-enhancing agent selected from the group consisting of C8-C20 branched alcohols, C8-C20 branched carboxylic acids or their water soluble salts, and mixtures thereof;
- c) a cross-linked deposition enhancing agent comprising one or more cross-linked polymers selected from the group consisting of acrylamides, acrylates, methacrylates, methacrylamides, cationic derivatives of said polymers, and mixtures thereof;
- d) an aqueous carrier.
