Claims

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.

2. A detergent composition according to claim 1, wherein said cationic polymer is characterized by having a cationic charge density of from about 1.2 meq/g to about 8 meq/g.

3. A detergent composition according to claim 1, wherein said cationic polymer is characterized by having a calculated cationic charge density of from about 1.5 meq/g to about 5 meq/g.

4. A detergent composition according to claim 1, wherein said cationic polymer comprises from about 5 mol % to about 98 mol % of a nonionic structural unit.

5. A detergent composition according to claim 4, wherein said cationic polymer comprises from about 10 mol % to about 95 mol % of said nonionic structural unit.

6. A detergent composition according to claim 1, wherein said cationic polymer comprises from about 2 mol % to about 100% of a cationic structural unit.

7. A detergent composition according to claim 6, wherein said cationic polymer comprises from about 5 mol % to about 95 mol % of said cationic structural unit.
