Abstract

Disclosed are oil-in-water (O/W) emulsions comprising (a) an aqueous dispersion of particles of at least one latex chosen from an acrylate latex, a polyurethane latex, or a silicone latex, (b) an oil phase, and (c) at least one surfactant, wherein the amount of the (a) aqueous dispersion of particles of at least one latex chosen from an acrylate latex, a polyurethane latex, or a silicone latex, in combination with the (c) at least one surfactant is sufficient to stabilize the oil-in-water emulsion. The disclosure also relates to hair styling and/or shaping compositions comprising the O/W emulsions, methods of making the emulsions, and methods of styling and/or shaping the hair.

First claim

What is claimed is:

1. A hair styling composition comprising an oil-in-water emulsion, the oil-in-water emulsion comprising:
(a) an aqueous dispersion of particles of a mixture of an acrylate latex and a polyurethane latex,
(b) an oil phase, and
(c) at least one surfactant,
wherein the amount of the (a) aqueous dispersion of particles in combination with the (c) at least one surfactant is sufficient to stabilize the oil-in-water emulsion;
wherein the total amount of surfactant present in the oil-in-water emulsion is not, by itself, sufficient to stabilize the emulsion; and
wherein the emulsion is stable.

2. The hair styling composition of claim 1 , wherein the oil phase comprises at least one water-insoluble component chosen from volatile oils, non-volatile oils, UV agents, and antioxidants.

3. The hair styling composition of claim 1 , wherein the at least one surfactant has an HLB value approximately the same as the HLB value of the water-insoluble component.

4. The hair styling composition of claim 2 , wherein the at least one water-insoluble component is present in the oil-in-water emulsion in an amount ranging from about 0.1% to about 50% by weight, relative to the total weight of the emulsion.

5. The hair styling composition of claim 3 , wherein the at least one surfactant is chosen from non-ionic and anionic surfactants.

6. The hair styling composition of claim 1 , wherein the aqueous dispersion of particles is present in the oil-in-water emulsion in an amount ranging from about 0.5% to about 10% by weight as polymeric active material (dry weight basis), relative to the total weight of the emulsion.

7. The hair styling composition of claim 1 , further comprising at least one additional component chosen from solvents, wax dispersions, oils, rheology modifiers, thickening agents, structuring agents, vitamins, plant extracts, or propellants.

8. The hair styling composition of claim 7 , comprising at least one solvent.

9. The hair styling composition of claim 8 , comprising at least one wax dispersion, wherein said wax dispersion comprises particles of natural and/or synthetic waxes dispersed in a surfactant mixture comprising nonionic and/or ionic surfactants.

10. A method of making an oil-in-water emulsion, said oil-in-water emulsion comprising:
(a) an aqueous dispersion of particles of a mixture of an acrylate latex and a polyurethane latex,
(b) an oil phase, and
(c) at least one surfactant,
wherein the amount of the (a) aqueous dispersion of particles in combination with the (c) at least one surfactant is sufficient to stabilize the oil-in-water emulsion; and
wherein the (c) at least one surfactant is present in the oil-in-water emulsion in an amount that is not, by itself, sufficient to stabilize the emulsion,
wherein the method comprises:
combining (a) the aqueous dispersion of particles, (b) the oil phase, and (c) the at least one surfactant,
optionally mixing the combined components, and
homogenizing the combined components under either low-pressure or high-pressure homogenization.

11. The method of claim 10 , wherein the oil-in-water emulsion is stable.

12. The method of claim 10 , comprising mixing (a) the aqueous dispersion, (b) the at least one oil phase, and (c) the at least one surfactant, prior to said homogenization.

13. The method of claim 8 , wherein the homogenization process is repeated from 2 to 10 times.

14. A method of styling the hair, said method comprising applying an oil-in-water emulsion to the hair, said oil-in-water emulsion comprising:
(a) an aqueous dispersion of particles of a mixture of an acrylate latex and a polyurethane latex,
(b) an oil phase, and
(c) at least one surfactant,
wherein the amount of the (a) aqueous dispersion of particles in combination with the (c) at least one surfactant is sufficient to stabilize the oil-in-water emulsion; and
wherein the (c) at least one surfactant is present in the oil-in-water emulsion in an amount that is not, by itself, sufficient to stabilize the emulsion.

15. A method of styling the hair, said method comprising applying to the hair a composition comprising:
(1) an oil-in-water emulsion comprising:
(a) an aqueous dispersion of particles of a mixture of an acrylate latex and a polyurethane latex,
(b) an oil phase, and
(c) at least one surfactant,

wherein the amount of the (a) aqueous dispersion of particles in combination with the (c) at least one surfactant is sufficient to stabilize the oil-in-water emulsion; and
wherein the (c) at least one surfactant is present in the oil-in-water emulsion in an amount that is not, by itself, sufficient to stabilize the emulsion; and
(2) at least one additional component chosen from solvents, wax dispersions, oils, rheology modifiers, thickening agents, structuring agents, propellants, vitamins, or plant extracts.

16. The method of claim 15 , wherein the composition comprises at least one solvent.

17. The method of claim 16 , wherein the composition further comprises at least one wax dispersion, wherein said wax dispersion comprises particles of natural and/or synthetic waxes dispersed in a surfactant mixture comprising nonionic and/or ionic surfactants.
