Abstract

An invention is disclosed which comprises siloxane-based polyamides as gelling agents for cosmetic products, methods for making such agents, formulations therof 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.
