Oleaginous pharmaceutical and cosmetic foam
First Claim
1. An oleaginous foamable therapeutic composition, comprising:
- a. about 70% to about 96.5% of a solvent phase, wherein the solvent phase is selected from the group consisting of a hydrophobic solvent, a silicone oil, and mixtures thereof;
b. at least one non-ionic surface-active agent at a concentration of about 0.1% to about 10% by weight of the total composition;
c. at least one gelling agent at a concentration of about 0.1% to about 5% by weight of the total composition;
d. at least one active agent;
e. at least one potent solvent selected from the group consisting of a hydrophobic solvent other than mineral oil;
a co-solvent;
an emollient; and
mixtures thereof, wherein the potent solvent solubilizes the active agent substantially better than mineral oil solubilizes the active agent; and
f. at least one liquefied or compressed gas propellant, wherein the composition forms a thermally stable breakable foam upon release from a pressurized container that collapses upon application of shear force; and
wherein the water content of the composition is less than about 30% by weight.

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.
