Claims20
A laundry detergent composition comprising a cationic polymer, a silicone, and a surfactant system,
- wherein said cationic polymer comprises:
- (i) from about 5 mol % to about 45 mol % of a first structural unit derived from (meth)acrylamide;
- (ii) from about 70 mol % to about 85 mol % of a second structural unit, wherein said second structural unit is derived from a cationic monomer selected from the group consisting of diallyl dimethyl ammonium salts (DADMAS), acrylamidopropyl trimethyl ammonium salts (APTAS), quaternized vinylimidazole (QVi), and mixtures thereof;
- and
- wherein said cationic polymer is characterized by a molecular weight of from about 5 kDaltons to about 200 kDaltons;
- and
- wherein said surfactant system comprises anionic surfactant and nonionic surfactant in a ratio of from about 1.1:1 to about 4:1,
- wherein said anionic surfactant comprises linear alkyl benzene sulfate (LAS) and alkyl ether sulfate (AES), and
- wherein the nonionic surfactant comprises one or more ethoxylated alcohols;
- wherein said detergent composition further comprises an adjunct selected from microencapsulates, enzymes, a soil release polymer, a hueing agent, or combinations thereof.
