Abstract
The present invention relates to lipstick compositions which comprise thermodynamically association structures, preferably lamellar liquid crystals and/or reverse hexagonal liquid crystals, which are used to deliver polar solvent/moisturizers through a non-polar (lipophilic) medium. The association structures consist essentially of from about 3% to about 96%, by weight, of polar solvent (e.g. glycerine) and from about 4% to about 97% of surfactant having a Krafft point at or below about ambient temperature.
