1. A laundry detergent composition comprising a cationic polymer, a silicone, and a surfactant system,
wherein said cationic polymer is characterized by having a calculated cationic charge density of equal to or greater than about 1 meq/g,
wherein said cationic polymer is further characterized by a molecular weight of from about 800 kDaltons to about 2000 kDaltons,
wherein said cationic polymer is acrylamide/MAPTAC,
wherein said cationic polymer is substantially free of any silicone-derived structural unit;
wherein said surfactant system comprises anionic surfactant and nonionic surfactant in a weight ratio of from about 1.5:1 to about 2.5:1, said anionic surfactant comprises linear alkyl benzene sulfate (LAS) and alkyl ether sulfate (AES), wherein said LAS and said AES are present in a weight ratio of from about 0.5:1 to about 2:1, and wherein the nonionic surfactant comprises one or more ethoxylated alcohols;
wherein said detergent composition further comprises an adjunct selected from the group consisting of microencapsulates, enzymes, a soil release polymer, a hueing agent, and combinations thereof.
