Abstract: A polyurethane elastomeric rubber composition containing a bio-based polyol cross-linked with a bio-based isocyanate using a urethanation catalyst such as a bismuth catalyst in the presence of a cosmetic emollient is disclosed. The cross-linked polyurethane elastomer rubber is in further aspect of the invention included in a gel after being milled in the presence of a bio-based emollient or mixture of bio-based emollients. The polyurethane elastomeric gel has good compatibility with cosmetic and natural oils and can be used as a gelling agent for these oils among other desirable cosmetic formulary roles.

Abstract: The present invention relates to gel compositions comprising a polyurethane elastomer. The polyurethane elastomer is formed from the reaction of a polyol, a polyisocyanate, and a polyurethane reaction catalyst in the presence of a topically acceptable carrier fluid. In some embodiments, the gel composition comprises a personal active ingredient or a healthcare active ingredient, which may be incorporated into the gel composition via a pre-load method or a post-load method. Also provided herein are gel pastes and topical formulations containing the polyurethane elastomers, and methods of making the same.
