摘要:
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.

A cosmetic composition includes (a) ether alcohols conforming to the general formula C.sub.(n) H.sub.(2n+2) O.sub.(n/2), where n is an integer which ranges 4 to 12; (b) a homopolymer of acrylic acid cross-linked with an allyl ether of pentaerythritol or an allyl ether of sucrose, or copolymers of acrylic acid or acrylate derivative/acrylonitrile copolymers, or polyacrylic acid; (c) a fragrance oil or oils, or cosmetically acceptable oils or oily-type materials; and (d) water.
摘要:
A liposome for use in encapsulating both hydrophobic and hydrophilic substances (i.e., a "payload"),is disclosed which is capable of delivering their load upon the occurrence of a trigger or control condition. The liposomes are formed to stably encapsulate a particular active agent to form a delivery vehicle for the agent. The liposomes of the delivery vehicle are stable in a particular environment but become unstable or permeable if passed from the stable environment (e.g., characteristic of a particular pH and/or temperature and/or ionic strength) to a changed or unstable environment, thereby delivering their payload.
