Oleaginous pharmaceutical and cosmetic foam
First Claim
1. A foamable composition, comprising a carrier comprising:
- a) about 70% to about 96.5% by weight of the carrier of a solvent selected from the group consisting of a co-solvent, a hydrophobic solvent, and mixtures thereof;
b) at least one gelling agent at a concentration of about 0.1% to about 5% by weight of the carrier; and
c) a surface-active agent;
wherein when mixed with a propellant in a canister, the composition is released as a breakable foam which collapses on application of shear force, and the breakable foam does not readily collapse at 37°

Abstract
The invention relates to stable oleaginous cosmetic or therapeutic foam compositions containing certain active agents, having unique therapeutic properties and methods of treatment using such compositions. The foamable composition includes at least one solvent selected from a hydrophobic solvent, a silicone oil, an emollient, a co-solvent, and mixtures thereof, wherein the solvent is present at a concentration of about 70% to about 96.5% by weight of the total composition, at least a non-ionic surface-active agent at a concentration of about 0.1% to less than about 10% by weight of the total composition; at least one gelling agent at a concentration of about 0.1% to about 5% by weight of the total composition; a therapeutically effective amount of at least one active agent; and at least one liquefied or compressed gas propellant, at a concentration of about 3% to about 25% by weight of the total composition.
