1. A laundry detergent composition comprising a non-polysaccharide cationic polymer, a silicone, and a surfactant system, wherein said cationic polymer is characterized by having a calculated cationic charge density of from about 4 meq/g to about 12 meq/g,wherein said cationic polymer is further cha
1. A laundry detergent composition comprising a non-polysaccharide cationic polymer, a silicone, and a surfactant system, wherein said cationic polymer is characterized by having a calculated cationic charge density of from about 4 meq/g to about 12 meq/g,wherein said cationic polymer is further characterized by a molecular weight of from about 15 to about 200 kDaltons,wherein said cationic polymer comprises from about 50 mol % to about 85 mol % of a cationic structural unit, wherein said cationic structural unit is derived from a cationic monomer selected from diallyl dimethyl ammonium salts (DADMAS);wherein said cationic polymer further comprises at least about 15 mol % of a nonionic structural unit, wherein said nonionic structural unit is derived from a vinyl formamide monomer; andwherein said surfactant system is present at a level of from about 1% to about 70%, by weight of the composition, and wherein said surfactant system comprises anionic surfactant and nonionic surfactant in a ratio of from about 1.1:1 to about 2.5, wherein said anionic surfactant comprises linear alkyl benzene sulfate (LAS) and alkyl ether sulfate (AES). 2. A detergent composition according to claim 1, wherein said cationic polymer comprises from about 15 mol % to about 30 mol % of said nonionic structural unit. 3. A detergent composition according to claim 1, wherein said cationic polymer comprises from about 70 mol % to about 85 mol % of said cationic structural unit. 4. A detergent composition according to claim 1, wherein said cationic polymer is characterized by having a cationic charge density of from about 4.5 to about 7 meq/g. 5. A detergent composition according to claim 1, wherein said cationic polymer is characterized by a molecular weight of from about 15 to about 100 kDaltons. 6. A detergent composition according to claim 1, wherein said cationic polymer is characterized by a molecular weight of from about 20 to about 50 kDaltons. 7. A detergent composition according to claim 1, wherein said cationic polymer is substantially free of any silicone-derived structural unit. 8. A detergent composition according to claim 1, wherein said silicone is an aminosilicone. 9. A detergent composition according to claim 1, wherein said silicone is present as a nanoemulsion, wherein said nanoemulsion is characterized by a mean particle size of from about 10 nm to about 500 nm. 10. A detergent composition according to claim 1, wherein said ratio of anionic surfactant to nonionic surfactant is about 2:1. 11. A detergent composition according to claim 1, wherein said LAS and said AES are present in a ratio of from about 0.5:1 to about 1.5:1. 12. A detergent composition according to claim 1, wherein said detergent composition further comprises from about 0.1% to about 4%, by weight of the composition, of fatty acid and/or a salt thereof. 13. A detergent composition according to claim 1, wherein said detergent composition further comprises an external structuring system comprising non-polymeric crystalline hydroxy-functional structurants, polymeric structurants, or mixtures thereof. 14. A detergent composition according to claim 1, wherein said detergent composition further comprises an adjunct selected from microencapsulates, enzymes, a soil release polymer, hueing dye, and combinations thereof. 15. A detergent composition according to claim 14, wherein said microencapsulates are perfume microcapsules. 16. A detergent composition according to claim 1, wherein said composition is a liquid. 17. A detergent composition according to claim 1, wherein said detergent composition is encapsulated in a pouch, wherein said pouch comprises water-soluble film. 18. A method of treating a fabric, comprising the step of contacting said fabric with said detergent composition of claim 1. 19. A detergent composition according to claim 1, wherein said diallyl dimethyl ammonium salts (DADMAS) comprise chloride (DADMAC). 20. A detergent composition according to claim 1, wherein said cationic polymer is characterized by a molecular weight of from about 47 to about 111 kDaltons.
