Hair care composition with encapsulated moisturizers and method to deliver extended moisture release to the hair
Methods and composition are provided for a hair care composition that comprises at least one encapsulated moisturizing ingredient. The composition comprises at least one surfactant, at least one capsule that encapsulates a benefit agent, and a carrier. The composition may further comprise additional components, which may be a function of the type of hair care composition. A method of using a hair care composition that comprises at least one encapsulated moisturizing ingredient is also provided.
1. A hair care composition, comprising: at least one surfactant selected from anionic, nonionic, zwitterionic and amphoteric surfactants;
at least one capsule, wherein the at least one capsule encapsulates a benefit agent, and the benefit agent provides at least 85% of the weight of the capsule; and a carrier,
wherein the at least one capsule comprises a shell
of hexamethylenediamine/methylenediphenyl diisocyanate copolymer.
2. The hair care composition of claim 1 , further comprising at least one additional capsule that encapsulates a fragrance ingredient.
3. The hair care composition of claim 1 , in which the at least one capsule becomes more brittle when the surrounding environment is dry.
4. The hair care composition of claim 1 , in which the at least one capsule releases the encapsulated benefit agent onto the hair in response to abrasion.
5. The hair care composition of claim 1 , in which the at least one surfactant provides at least 6% by weight of the hair care composition, relative to the total weight of the composition.
6. The hair care composition of claim 1 , in which the carrier is water.
7. The hair care composition of claim 1 , in which the at least one capsule that encapsulates a benefit agent has a size ranging from about 5 micrometers (μm) to about 75 μm.
8. The hair care composition of claim 7 , in which the at least one capsule that encapsulates a benefit agent has a size ranging from about 10 μm to about 50 μm.
9. The hair care composition of claim 1 , in which the benefit agent is the only component encapsulated by the at least one capsule.
10. The hair care composition of claim 1 , in which the benefit agent comprises an agent selected from oils, esters, oil soluble vitamins.
11. The hair care composition of claim 1 , in which the at least one capsule is present in the composition at a concentration ranging from about 0.001% to 20.00% by weight.
12. The hair care composition of claim 11 , in which the at least one capsule is present in the composition at a concentration ranging from about 0.10% to about 2.00% by weight.
13. The hair care composition of claim 1 , further comprising a suspending polymer.
14. The hair care composition of claim 1 , wherein the benefit agent comprises a triglyceride.
15. A hair care composition, comprising: at least one surfactant selected from anionic, nonionic, zwitterionic and amphoteric surfactants;
at least one capsule, wherein the at least one capsule encapsulates a benefit agent, and the benefit agent provides at least 85% of the weight of the capsule; and a carrier,
wherein the at least one capsule comprises a shell of guanidine carbonate/hexamethylene diisocyanate isocyanurate trimer/methylenediphenyl diisocyanate crosspolymer.
