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.
Claims9
A non-aqueous gel composition comprising a mixture of a cross-linked polyurethane elastomer rubber composition, comprising (a) a cross-linked polyurethane elastomer rubber;
- (b) a cosmetic emollient and (c) a urethanation catalyst, wherein the cosmetic emollient forms a solvent matrix substantially surrounding the cross-linked polyurethane elastomer rubber in micronized form and at least one cosmetic emollient.
