ABSTRACT:
The invention relates to a series of novel silicone fatty esters, specifically dimethicone copolyol erucate esters. This class of compounds provides has a unique combination of properties including clarity and liquidity and oxidative stability and water solubility of the silicone ester per se, and the ability to provide outstanding softening and wet comb lubrication, as well as actually strengthening the hair. These properties are highly desirable in cosmetic products. The compounds of the present invention are prepared by reacting the hydroxyl group in a silicone polymer with erucic acid, or an oil high in erucic acid like crambe oil. The compounds of the present invention have more than 40% by weight of erucic groups in the molecule. The concentration of this key component has been found to be critical to performance.
