A conditioner composition that increases the deposition and retention of benefit agent containing polyacrylate microcapsules onto hair. The conditioner composition is based on the combination of anionic charged polyacrylate microcapsules, deposition aids, conditioner agents, and a carrier.
1. A method of making a conditioner composition, said method comprising: combining a premix with a conditioning agent and a carrier to form a conditioner composition;wherein said conditioning agent is selected from the group consisting of a cationic surfactant, a high melting point fatty compound, a
1. A method of making a conditioner composition, said method comprising: combining a premix with a conditioning agent and a carrier to form a conditioner composition;wherein said conditioning agent is selected from the group consisting of a cationic surfactant, a high melting point fatty compound, a silicone compound, and combinations thereof;wherein said premix comprises a plurality of anionic charged polyacrylate microcapsules and a deposition aid selected from the group consisting of cationic deposition polymer, aminosilicone, and combinations thereof;wherein the weight ratio of the anionic charged polyacrylate microcapsule to the deposition aid is from about 0.5:30 to about 20:1; andwherein the conditioning agent is in an amount of from about 2% to about 25%, the anionic charged polyacrylate microcapsule is in an amount of from about 0.001% to about 10%, and the deposition aid is in an amount of from about 0.015 to about 2% of the composition. 2. The method of claim 1, wherein the anionic charged polyacrylate microcapsules comprises an anionic emulsifier. 3. The method of claim 2, wherein the anionic emulsifier surrounds at least a part of the external surface of the polyacrylate microcapsule, or is physically or chemically bound to the external surface of the polyacrylate microcapsule. 4. The method of claim 2, wherein the anionic emulsifier and the polyacrylate microcapsule are mixed such that the weight ratio of the anionic emulsifier to the polyacrylate microcapsule is from about 1.0:40 to about 0.5:5. 5. The method of claim 1, wherein the anionic charged polyacrylate microcapsule and the deposition aid are mixed such that the weight ratio of the anionic charged polyacrylate microcapsule to the deposition aid is from about 1.0:0.01 to about 1.0:10. 6. The method 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. 7. The method of claim 1, wherein the anionic charged polyacrylate microcapsules have a particle size of from about 2 microns to about 80 microns. 8. The method of claim 2, wherein the polyacrylate microcapsules have a core and a shell that encapsulates said core. 9. The method of claim 8, wherein the core comprises from about 6% to about 99.9% of a benefit agent. 10. The method of claim 9, wherein the benefit agent is selected from the group consisting of perfumes; brighteners; enzymes; perfume delivery system; conditioning agents; moisturizers; anti-microbial agents; thickeners; sensates; attractants; dyes; pigments; bleaches; and mixtures thereof. 11. The method of claim 1, wherein the cationic deposition polymer is selected from the group consisting of starches, guar, cellulose, cassia, locust bean, Konjac, Tara, galactomanna, polyDADMAC, Tapioca starch, and polyTriquat. 12. The method 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. 13. The method of claim 1, wherein the deposition aid comprises an aminosilicone. 14. The method of claim 1, wherein the carrier comprises water and water solutions of lower alkyl alcohols and polyhydric alcohols. 15. The method of claim 1, wherein the conditioner composition is in the form of a gel, and wherein the gel comprises less than about 45% water. 16. The method of claim 2, wherein the anionic emulsifier and the polyacrylate microcapsule are mixed such that the weight ratio of the anionic emulsifier to the polyacrylate microcapsule is from about 1.0:200 to about 1:20. 17. The method of claim 2, wherein the anionic emulsifier and the polyacrylate microcapsule are mixed such that the weight ratio of the anionic emulsifier to the polyacrylate microcapsule is from about 1.0:1000 to about 2:5. 18. The method of claim 2, wherein the anionic emulsifier is selected from the group consisting of: carboxyvinylpolymer; acrylate copolymers; Acrylic acid/vinyl ester copolymer/Acrylates/Vinyl Isodecanoate crosspolymer; Acrylates/Palmeth-25 Acrylate copolymer; Acrylate/Steareth-20 Itaconate copolymer; Acrylate/Ceteth-20 Itaconate copolymer; Polystyrene sulphonate; copolymers of methacrylic acid and acrylamidomethylpropane sulfonic acid; copolymers of acrylic acid and acrylamidomethylpropane sulfonic acid; carboxymethycellulose; carboxy guar; copolymers of ethylene and maleic acid; acrylate silicone polymer; and mixtures thereof. 19. A method of making a conditioner composition, said method comprising: combining a plurality of anionic charged polyacrylate microcapsules with a deposition aid selected from the group consisting of cationic deposition polymer, aminosilicone, and combinations thereof to form a premix; andcombining said premix with a conditioning agent and a carrier to form the conditioner composition;wherein said conditioning agent is selected from the group consisting of a cationic surfactant, a high melting point fatty compound, a silicone compound, and combinations thereof; andwherein the weight ratio of the anionic charged polyacrvlate microcapsule to the deposition aid is from about 0.5:30 to about 20:1; andwherein the conditioning agent is in an amount of from about 2% to about 25%, the anionic charged polyacrylate microcapsule is in an amount of from about 0.001% to about 10%, and the deposition aid is in an amount of from about 0.015 to about 2% of the composition.
