Abstract

Also provided are methods of using same.

First claim

What is claimed is:

1. A hair styling composition consisting of:
a. about 0.01 to about 10%, by weight of the total composition, of at least one alkoxysilane chosen from 3-aminopropyltriethoxysilane, 3-aminopropylmethyldiethoxysilane, N-(2-aminoethyl)-3-aminopropylltriethoxysilane, and 3-(2-aminoethylamino)propylmethyldiethoxysilane;
b. at least one acid in an amount to neutralize about 30 to about 100% of the at least one alkoxysilane;
c. about 0.1 to about 20%, by weight of the total composition, of at least one ionic latex film former chosen from acrylates copolymer, polyacrylate-2 crosspolymer, styrene-acrylic copolymer, acrylates copolymer, acrylates/hydroxyesters acrylates copolymer, styrene/acrylates copolymer, polyquaternium-91 and polyacrylate-15, styrene/acrylates/ammonium methacrylate copolymer, acrylates/beheneth-25 methacrylate crosspolymer copolymer, acrylates/steareth-20-25 methacrylate crosspolymer copolymer, polyacrylate-15 and mixtures thereof;
d. water;
e. optionally, at least one a nonionic latex film former;
f. optionally, at least one water-miscible organic solvent;
g. optionally, at least one coalescing agent;
h. optionally, at least one plasticizer; and
i. optionally, anionic surfactants or cationic surfactants or emulsifying agents.

2. The hair styling composition of claim 1 , wherein the at least one nonionic latex film former is present in an amount of from about 0.1 to about 10% by weight of the total composition.

3. The hair styling composition of claim 1 , wherein the at least one plasticizers is present and selected from the group consisting of glycols, derivatives thereof, and mixtures thereof.

4. The hair styling composition of claim 1 , wherein the at least one water-miscible organic solvent is present and selected from the group consisting of monoalcohols containing from about 1 to 5 carbon atoms.

5. A method of styling hair, the method comprising applying the hair styling composition of claim 1 to hair.
