Cosmetic and pharmaceutical foam

Abstract

The invention relates to an alcohol-free cosmetic or pharmaceutical foam carrier comprising water, a hydrophobic solvent, a foam adjuvant agent, a surface-active agent and a water gelling agent. The cosmetic or pharmaceutical foam carrier does not contain aliphatic alcohols, making it non-irritating and non-drying. The alcohol-free foam carrier is suitable for inclusion of both water-soluble and oil soluble pharmaceutical and cosmetic agents.

1 . An alcohol-free foamable pharmaceutical or cosmetic carrier, comprising:
 (a) a foamable composition comprising:
 about 2-75% by weight of composition of a liquid, non-volatile hydrophobic solvent; 
 about 80-98% by weight of composition of water; 
 about 0.1% to 5% by weight of composition of a foam adjuvant agent selected from the group consisting of fatty alcohols, fatty acids, hydroxyl-substituted fatty alcohols, hydroxyl-substituted fatty acids, and fatty acids and fatty alcohols including at least one double bond in its carbon atom chain; 
 about 0.1% to 5% by weight of composition of a surface-active agent; and 
 about 0.1% to 5% by weight of composition of a water gelling agent; 
   and   (b) a liquefied or compressed gas propellant in a container,
 which upon release provides a breakable foam suitable for topical or mucosal administration.
