A shampoo composition that increases the deposition and retention of benefit agent containing polyacrylate microcapsules onto hair during the cleansing process. The shampoo composition is based on the combination of anionic charged polyacrylate microcapsules, cationic deposition polymers, detersive surfactant, and a carrier.
1. A composition comprising: (a) from about 0.01% to about 50%, by weight of the composition, of an anionic charged polyacrylate microcapsule;(b) from about 0.01% to about 2%, by weight of the composition, of a cationic deposition polymer, wherein the cationic deposition polymer is coated on the wal
1. A composition comprising: (a) from about 0.01% to about 50%, by weight of the composition, of an anionic charged polyacrylate microcapsule;(b) from about 0.01% to about 2%, by weight of the composition, of a cationic deposition polymer, wherein the cationic deposition polymer is coated on the wall of the anionic charged polyacrylate microcapsule in a weight ratio of the anionic polyacrylate microcapsule to the cationic deposition polymer of from about 0.5:30 to about 20:1;(c) from about 2% to about 50%, by weight of the composition, of a detersive surfactant; and(d) from about 20% to about 95%, by weight of the composition, of a carrier. 2. The composition of claim 1, wherein the anionic charged polyacrylate microcapsule is made by adding an anionic emulsifier to the polyacrylate microcapsule during the polyacrylate microcapsule making process. 3. The composition of claim 1, wherein the anionic charged polyacrylate microcapsule and the cationic deposition polymer are mixed such that the weight ratio of the anionic charged polyacrylate microcapsule to the cationic deposition polymer is from about 5:15 to about 15:1. 4. The composition of claim 2, wherein the anionic emulsifier is selected from the group consisting of: poly(meth)acrylic acid; copolymers of (meth)acrylic acids and its (meth)acrylates with C1-C22 alkyl; copolymers of (meth)acrylic acids and (meth)acrylamide; and mixtures thereof. 5. The composition of claim 1, wherein the anionic charged polyacrylate microcapsule has a median particle size of from about 1 microns to about 80 microns. 6. The composition of claim 1, wherein the polyacrylate microcapsule has a core and a shell that encapsulates said core. 7. The composition of claim 6, wherein the core comprises from about 6% to about 99.9% of a benefit agent. 8. The composition of claim 7, wherein the benefit agent is selected from the group consisting of perfumes; brighteners; enzymes; sensates; attractants; dyes; pigments; bleaches; anti-dandruff agents; and mixtures thereof. 9. The composition of claim 1, wherein the composition further comprises an anti-dandruff agent. 10. The composition of claim 1, wherein the cationic deposition polymer is a synthetic polymer or a naturally derived cationic polymer derived from the group consisting of starches, guar, cellulose, cassia, locust bean, konjac, tara, galactomanna, and tapioca starch. 11. The composition of claim 1, wherein the cationic deposition polymer is a water-soluble polymer with a charge density of from about 0.5 milliequivalents per gram to about 12 milliequivalents per gram, and wherein the cationic deposition polymer has a molecular weight of about 100,000 Daltons to about 5,000,000 Daltons. 12. The composition of claim 1, wherein the detersive surfactant is selected from the group consisting of anionic surfactants, zwitterionic surfactants, amphoteric surfactants, and combinations thereof. 13. The composition of claim 1, wherein the carrier comprises either water or water solutions of lower alkyl alcohols and polyhydric alcohols. 14. The composition of claim 1, wherein the composition is in the form of a gel. 15. The composition of claim 14, wherein the gel has a neat viscosity of about 1,000 cps to about 10,000 cps. 16. The composition of claim 1, wherein said anionic polyacrylate microcapsule comprises a perfume oil and isopropyl myristate.
