Silicone polyurethane blends
The invention describes the unexpected characteristics of blends, including crosslinked reaction products of elastomeric silicone polymers with various polyurethanes and their applications in personal care products.
1. A composition comprising an admixture of a silicone elastomer and a polyurethane compound wherein said silicone elastomer comprises about 0.5% to about 99.5% by weight of said admixture and said polyurethane compound comprises about 0.5% to about 99.5% by weight of said admixture, wherein said polyurethane is a compound of formula 4:
where n is 5 to 100, and
R 10 is a —CH 2 —CH—(CH—(CH 2 ) 7 radical.
2. A composition comprising an admixture of a silicone elastomer and a polyurethane compound wherein said silicone elastomer comprises about 0.5% to about 99.5% by weight of said admixture and said polyurethane compound comprises about 0.5% to about 99.5% by weight of said admixture, wherein said polyurethane is a compound of formula 5:
where n is 5 to 100, and
R 10 is a —CH 2 —CH═CH—(CH 2 ) 7 radical.
3. A personal care composition comprising a composition according to claim 1 in combination with at least two components selected from the group consisting of water, an aqueous solvent, a non-aqueous solvent, emollients, humectants, oils, conditioning agents, surfactants, thickeners/thickening agents, stiffening agents, emulsifiers, medicaments, fragrances, preservatives, deodorant components, anti-perspirant compounds, skin protecting agents, pigments, dyes, coloring agents, sunscreens and mixtures thereof.
