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, and (b) an oil phase, wherein the aqueous dispersion of particles of at least one latex is present in the O/W emulsion in an amount sufficient to stabilize the O/W emulsion. The disclosure also relates to hair styling and/or shaping compositions comprising the O/W emulsions, methods of making the compositions, and methods of styling and/or shaping the hair.

First claim

What is claimed is:

1. A method for styling hair comprising applying to the hair a composition comprising an oil-in-water emulsion, the oil-in-water emulsion comprising:
(a) an aqueous phase comprising a dispersion of particles of latex chosen from Polyurethane-34, Polyurethane-32, Polyurethane-35, Polyurethane-48, Polyurethane-1, Polycarbamyl Polyglycol Ester, Polyurethane-2 (and) Polymethyl Methacrylate, Acrylates Copolymer, Polyacrylate-2 Crosspolymer, Styrene/Acrylic copolymer, Acrylates/Ethylhexyl Acrylate Copolymer, Styrene/Acrylates Copolymer, Styrene/Acrylates/Ammonium Methacrylate Copolymer, Acrylates/Hydroxyesters Acryaltes Copolymer, and divinyldimethicone/dimethicone copolymer/C 12 -C 13 Pareth-3/C 12 -C 13 Pareth-23; and
(b) an oil phase,

wherein the dispersion of particles of latex is present in the aqueous phase of the oil-in-water emulsion in an amount ranging from about 0.1% to about 10% by weight as polymeric active material on a dry weight basis, relative to the total weight of the aqueous phase.

2. The method of claim 1 , wherein the oil phase comprises a water-insoluble component chosen from volatile oils, non-volatile oils, UV agents, and antioxidants.

3. The method of claim 2 , wherein the water-insoluble component is present in the oil-in-water emulsion in an amount ranging from about 0.1% to about 40% by weight, relative to the total weight of the emulsion.

4. The method of claim 1 , wherein the dispersion of particles of latex 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 on a dry weight basis, relative to the total weight of the emulsion.

5. The method of claim 1 , wherein the weight ratio of active material of (a) the aqueous phase comprising a dispersion of latex to (b) the water-insoluble component ranges from about 10:1 to about 1:20.

6. The method of claim 1 , wherein the composition further comprises a surfactant.

7. The method of claim 6 , wherein the surfactant is present in an amount up to about 1% by weight, relative to the total weight of the emulsion.

8. The method of claim 1 , wherein the composition further comprises an additional component chosen from solvents, wax dispersions, oils, surfactants, rheology modifiers, thickening agents, structuring agents, skin active agents, vitamins, plant extracts, and propellants.

9. The method of claim 1 , wherein the composition further comprises a solvent and a wax dispersion, wherein the wax dispersion comprises particles of natural and/or synthetic waxes dispersed in a surfactant mixture comprising nonionic and/or ionic surfactants.
