Abstract
Abstract Disclosed is a cosmetic composition comprising a resin, a polysiloxane, a polyolefin that is fluid at room temperature, and at least one hardening agent. Suitable coloring materials include dyes, pigments and pearling agents. The compositions of the present invention may be molded into the shape of a lipstick. They may also be applied in the form of a cream, especially when the composition is intended to be used as a lip gloss or as a lip balm.
