An invention is disclosed which comprises siloxane-based polyamides as gelling agents for cosmetic products, methods for making such agents, formulations thereof and cosmetic formulations therewith. These polyamides contain siloxane groups in the main chain and act to thicken compositions containing volatile and/or non-volatile silicone fluids. Cosmetic compositions may be made by adding at least one active ingredient such as an antiperspirant.

528 26, 528 31, 528 15

A method of making siloxane-based polyamides which includes at least one repeating unit represented by the formula wherein X is a linear or branched C -C alkylene chain; Y is a linear or branched C -C alkylene chain; DP is an integer having a value of 10-500; n is an integer having a value 1-500. The method involves heating an intimate reaction mixture containing an olefinic acid and an organic diamine at a temperature greater than 100Â C. and forming an organic diamide; and thereafter reacting the organic diamide with a hydride-terminated polydimethylsiloxane in the presence of a hydrosilylation catalyst to form the siloxane-based polyamide.

Siloxane-based polyamide elastomers can be prepared by heating a reaction mixture containing an olefinic acid and an organic amine to form an organic amide, and reacting the organic amide with a hydride functional polyorganosiloxane in the presence of a hydrosilylation catalyst to form the siloxane-based polyamide elastomer. The hydride functional polyorganosiloxane contains at least one pendant hydrogen. The elastomers are useful additives in personal care products and can be applied to the hair, the skin, or the underarm. They can also be used to modify thermoplastic nylons, and for treating woven and non-woven textiles, such as air bags, carpeting, and apparel.
