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: Cosmetic compositions useful intended for use in cosmetics and personal care formulations are disclosed. The cosmetic compositions include a micronized, substantially uniform powder mixture of a ferment containing a polyhydroxyalkanoate such as polyhydroxybutyrate and an amino acid derivative such as the lysine derivative N6-lauroyl-L-lysine. The cosmetic powder compositions can be intermediates that enhance the textural profile of cosmetics providing sensorial improvement, and/or soft-focus effects, line blurring effects by filling unevenness in the skin, making it appear smoother with less skin imperfections and wrinkles. The powder-based compositions can serve as detackifiers and/or viscosity modifiers due to its ability to absorb oil. The powder provides formulation options for cosmetics and personal care formulas prepared from biobased and biodegradable materials. Methods of preparing the powder compositions, as well as cosmetics containing the composition are also disclosed.
