Durable hold hair styling compositions and method of use
The present invention relates to improved hair styling compositions and methods of using such compositions. More particularly, the present invention relates to hair styling compositions with improved durability performance of the hair fixative resins, including resistance to high humidity, low tackiness, and good hold.
1. A composition comprising:
a) a first polymer or polymer mixture with a glass transition temperature (“Tg”) from 75° C. to 130° C.;
b) a second polymer or polymer mixture with a Tg from 20° C. to 35° C.; and
c) one or more cosmetically acceptable solvents;
wherein when the first polymer or polymer mixture and the second polymer or polymer mixture are dissolved together in a cosmetically acceptable solvent, which may be the same as or different than the solvent in c), and then dried to form a film, the film has a tensile storage modulus at 20° C. of from 1×10 10 Pascal to 1×10 8 Pascal and a storage modulus at 70° C. of from 1×10 9 Pascal to 1×10 6 Pascal; and
wherein the first polymer and the second polymer are independently selected from block, graft, and branched homopolymers and copolymers derived from one or more monomers selected from methacrylic acid; acrylic acid; methacrylate esters, acrylate esters, styrene, substituted styrenes, vinyl esters of organic acids, N-vinyl compounds, acrylamide; methacrylamide; substituted acrylamides, amine-functional acrylamides, substituted methacrylamides; hydroxylalkyl methacrylates, hydroxylalkyl acrylates, dienes, vinyl ethers, acid containing monomers; and functional monomers selected from maleic acid, maleic anhydride, fumaric acid, α-methylene glutaric acid, itaconic acid, itaconic anhydride, citraconic acid, mesaconic acid, cyclohexenedicarboxylic acid, 2-acrylamido-2-methylpropanesulfonic acid, monoacryloxyethyl , and water-soluble salts thereof.
2. A hair styling composition comprising:
a) a composition of claim 1 ; and
b) one or more cosmetically acceptable solvents; and
c) one or more cosmetically acceptable ingredients selected from perfumes, dyostuffs, preservatives, sequestering agents, thickeners, silicones, softeners, foam synergistic agents, foam stabilizers, sun filters, peptizing agents, conditioning agents, shine agents, proteins, herbals, botanicals, neutralizers, plasticizers, and anionic, non-ionic, cationic, or amphoteric surfactants, and mixtures thereof.
