Abstract

The present invention is directed to a hair styling composition and methods of using the composition, wherein the composition comprises: (a) an aqueous dispersion containing: (i) at least one solid wax particle having a particle size ranging from equal to or greater than 1 micron to about 100 microns and comprising at least one wax having a melting point of greater than 35° C.; (ii) a surfactant mixture comprising at least one nonionic surfactant and at least one ionic surfactant; and (iii) water; and (b) at least one cosmetically acceptable carrier.

First claim

What is claimed is:

1. A method of shaping hair, the method comprising:
(1) applying onto the hair, a hair styling composition comprising:
(a) from about 0.5% to about 20% by weight, based on the total weight of the hair styling composition, of an aqueous dispersion containing:
(i) at least one solid wax particle having a particle size ranging from about 5 microns to about 25 microns and comprising at least one wax chosen from beeswax, hydrogenated myristyl olive esters, hydrogenated stearyl olive esters, VP/eicosene copolymer, ditrimethyloylpropane tetrastearate and C30-45 alkyldimethylsilyl propylsilsesquioxane, and wherein the at least one wax is present in an amount of from about 20% to about 40% by weight, based on the total weight of the aqueous dispersion;
(ii) from about 1.5% to about 3.0% by weight of a surfactant mixture comprising:
at least one nonionic surfactant chosen from PEG-30 glyceryl stearate, sorbitan palmitate and mixtures thereof; and
from about 5% to about 20% by weight, based on the total weight of the surfactant mixture, at least one cationic surfactant chosen from cetrimonium chloride, behentrimonium chloride, dipalmitoylethvl hydroxvethylmonium methosulfate, distearoylethyl hydroxyethylmonium methosulfate, and mixtures thereof;
wherein the surfactant mixture is free of amphoteric surfactants;

(iii) water; and
(iv) an optional ingredient comprising at least one additional ingredient chosen from a wax having a melting point of 35° C. or less, oils, emulsifying polymers, sunscreen agents, pigments/dyes, silicas talc, clays, and perfumes;

(b) at least one cosmetically acceptable carrier; and
(c) optionally, at least one auxiliary agent; and

(2) heating the hair in order to melt the at least one solid wax particle.

2. A method of shaping hair, the method comprising:
(1) applying onto the hair, a hair styling composition comprising:
(a) from about 0.5% to about 20% by weight, based on the total weight of the hair styling composition, of an aqueous dispersion containing:
(i) at least one solid wax particle having a particle size ranging from about 5 microns to about 25 microns and comprising at least one wax chosen from beeswax, hydrogenated myristyl olive esters, hydrogenated stearyl olive esters, VP/eicosene copolymer, ditrimethyloylpropane tetrastearate and C30-45 alkyldimethylsilyl propylsilsesquioxane, and wherein the at least one wax is present in an amount of from about 20% to about 40% by weight, based on the total weight of the aqueous dispersion;
(ii) from about 1.5% to about 3.0% by weight of a surfactant mixture comprising:
at least one nonionic surfactant chosen from PEG-30 glyceryl stearate, sorbitan palmitate and mixtures thereof; and
from about 5% to about 20% by weight, based on the total weight of the surfactant mixture, at least one anionic surfactant chosen from, disodium stearoyl glutamate and sodium stearoyl glutamate, and mixtures thereof;
wherein the surfactant mixture is free of amphoteric surfactants;

(iii) water; and
(iv) an optional ingredient comprising at least one additional ingredient chosen from a wax having a melting point of 35° C. or less, oils, emulsifying polymers, sunscreen agents, pigments/dyes, silicas talc, clays, and perfumes;

(b) at least one cosmetically acceptable carrier; and
(c) optionally, at least one auxiliary agent; and

(2) heating the hair in order to melt the at least one solid wax particle.

3. The method of claim 1 , wherein the cosmetically acceptable carrier is chosen from water, volatile organic solvents, non-volatile organic solvents, silicones, polyols, glycols, glycol ethers, oils, and mixtures thereof.

4. The method of claim 1 , wherein the at least one auxiliary agent is chosen from liquid lipids/oils, film forming polymers, rheology modifiers, sunscreens agents, pigments, dyes, silica, clays, humectants and moisturizing agents, emulsifying agents, structuring agents, propellants, surfactants, shine agents, conditioning agents, cosmetically, dermatologically pharmaceutically active agents, vitamins, and plant extracts.

5. The method of claim 1 , wherein the aqueous dispersion further comprises at least one auxiliary agent chosen from film forming polymers, rheology modifiers, humectants and moisturizing agents, structuring agents, propellants, shine agents, conditioning agents, cosmetically, dermatologically pharmaceutically active agents, vitamins, and plant extracts.

6. The method of claim 1 , wherein the composition further comprises at least one rheology modifier chosen from acrylate polymers, acrylic-based polymers and cellulose-based thickening agents.

7. The method of claim 1 , wherein the composition further comprises a volatile organic solvent.

8. The method of claim 1 , wherein the composition further comprises a propellant.

9. The method of claim 2 , wherein the cosmetically acceptable carrier is chosen from water, volatile organic solvents, non-volatile organic solvents, silicones, polyols, glycols, glycol ethers, oils, and mixtures thereof.

10. The method of claim 2 , wherein the at least one auxiliary agent is chosen from liquid lipids/oils, film forming polymers, rheology modifiers, sunscreens agents, pigments, dyes, silica, clays, humectants and moisturizing agents, emulsifying agents, structuring agents, propellants, surfactants, shine agents, conditioning agents, cosmetically, dermatologically and pharmaceutically active agents, vitamins, and plant extracts.

11. The method of claim 2 , wherein the aqueous dispersion further comprises at least one auxiliary agent chosen from film forming polymers, rheology modifiers, humectants and moisturizing agents, structuring agents, propellants, shine agents, conditioning agents, cosmetically, dermatologically pharmaceutically active agents, vitamins, and plant extracts.

12. The method of claim 2 , wherein the composition further comprises at least one rheology modifier chosen from acrylate polymers, acrylic-based polymers and cellulose-based thickening agents.

13. The method of claim 2 , wherein the composition further comprises a volatile organic solvent.

14. The method of claim 2 , wherein the composition further comprises a propellant.
