First claim

Opening claim text (preview).

What is claimed is: 1. A foamable composition formulated for skin delivery of an active agent comprising: a minocycline in a therapeutically effective amount of about 1 to about 5% by weight of the composition; a short chain alcohol comprising ethanol; about 12% to about 30% by weight of the composition of a protic polar solvent comprising propylene glycol; a polymeric agent comprising a cellulose ether; a modulating agent comprises an antioxidizing agent; a metal; an essential oil; wherein the foamable composition is surfactant free; and wherein the composition is waterless and essentially free of fatty alcohol. 2. The foamable composition according to claim 1 , wherein the minocycline is a minocycline hydrochloride. 3. The foamable composition according to claim 1 , wherein the therapeutically effective amount is about 1%. 4. The foamable composition according to claim 1 , wherein the therapeutically effective amount is about 4%. 5. The foamable composition according to claim 1 , wherein the short chain alcohol is present in an amount of at least 55% by weight of the composition. 6. The foamable composition according to claim 1 , wherein the cellulose ether is a hydroxypropyl cellulose. 7. The foamable composition according to claim 1 , wherein the modulating agent is present in an amount ranging from about 0.1% to about 10% by weight of the composition. 8. The foamable composition according to claim 7 , wherein the modulating agent is present in an amount ranging from about 1% to about 5% by weight of the composition. 9. The foamable composition according to claim 1 , wherein the cellulose ether is present in an amount ranging from about 0.5% to about 1% by weight of the composition. 10. The foamable composition according to claim 1 , wherein: the minocycline is minocycline hydrochloride; and the cellulose ether is a hydroxypropyl cellulose. 11. The foamable composition according to claim 10 , wherein: the ethanol is present in an amount of at least 55% by weight of the composition; the hydroxypropyl cellulose is present in an amount of about 0.5% to about 1% by weight of the composition; and the modulating agent is present in an amount ranging from about 0.1% to about 10% by weight of the composition. 12. The foamable composition according to claim 11 , wherein the therapeutically effective amount is about 1% by weight of the composition. 13. The foamable composition according to claim 11 , wherein the therapeutically effective amount is about 4% by weight of the composition. 14. The foamable composition according to claim 1 , wherein the liquefied or compressed gas propellant is present in an amount ranging from about 3% to about 25% by weight of the composition.
