The present disclosure generally provides topically applicable insect repelling compositions, and in some embodiments, topically applicable insect repelling and UV protecting compositions. The compositions comprise a polymerization product of a polyol, a diisocyanate and at least one insect-repelling compound. The resulting polymers advantageously bond superficially to skin or hair, thereby localizing repellents and preventing systemic absorption. While not being bound by theory, it is believed that the localization of repellents to the surface of the skin renders them safer, wherein such repellents are not vaporized and do not have a disagreeable odor. The repellents advantageously interact with tactile insect activity, thereby preventing parasitic activity, such as drawing blood or the communication of pathogens.

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.
