Abstract

The present invention relates to stable substantially non-aqueous, non-alcoholic, non-silicone, foamable carrier compositions comprising petrolatum or mixtures thereof, at least one foam agent, at least one propellant, and with and without the addition of an active agent. The formulations may contain a solvent substantially miscible therein. The present invention further provides a method of treating, alleviating or preventing a disorder of mammalian subject in need thereof, comprising administering the above-mentioned compositions to an afflicted target site of said mammalian subject.

First claim

What is claimed is:

1. A foamable composition comprising:
a foamable carrier and at least one liquefied or compressed gas propellant, the foamable carrier comprising:
(1) a petrolatum or mixtures thereof at a concentration of about 50% to about 95% by weight of the foamable carrier;
(2) a solvent substantially miscible in the petrolatum at a concentration of 0% to about 50% by weight of the foamable carrier; and
(3) a foam adjuvant comprising a fatty alcohol and either a surfactant or a surfactant system at a concentration of about 0.1% to about 20% by weight of the foamable carrier;
wherein the surfactant is selected from the group consisting of a polyoxyethylene fatty acid ester, a polyoxyethylene alkylyl ether, a sucrose ester, a monoglyceride, a diglyceride, glucose methyl stearate, methyl glucose sesquistearate, polyglyceryl 10 laurate, sodium stearyl phtalmate and a mixture of any two or more thereof; or
wherein the surfactant system is a combination of at least two surfactants selected from the group consisting of at least two polyoxyethylene alkyl ethers, steareth 2 and steareth 20, steareth 2 and Steareth 21, polyoxyethylene (40) stearate and polyoxyethylene (100) stearate, a combination of sucrose esters, sucrose stearate and sucrose distearate, and glyceryl stearate and PEG-100 stearate;
wherein the composition is non-aqueous;
wherein the composition does not contain a sorbitan fatty acid ester;
wherein the ratio of the foamable carrier to the propellant ranges from about 100:10 to about 100:35; and
wherein the composition is stored in a pressurized container and upon release expands to form a breakable foam.

2. The composition of claim 1 , wherein the foamable carrier further comprises at least one active pharmaceutical agent.

3. The composition of claim 1 , wherein the composition is flowable and/or is shakable or substantially so when stored in a pressurized container and upon release expands to form a breakable foam having no substantial or sustained cooling effect and having a foam hardness in the range of about 5 g to about 100 g.

4. The composition of claim 1 , wherein the solvent is hydrophobic and is selected from the group consisting of an unctuous additive, an oil, a therapeutic oil, a PPG alkyl ether, or a combination of any two or more thereof.

5. The composition of claim 4 , wherein the solvent comprises a PPG15 stearyl ether.

6. The composition of claim 4 , wherein the solvent comprises a mineral oil.

7. The composition of claim 4 , wherein the solvent comprises a medium chain triglyceride oil.

8. The composition of claim 1 , wherein the carrier has a viscosity from about 12,000 cP to about 500,000 cP.

9. The composition of claim 1 , wherein the propellant dissolves in the composition.

10. The composition of claim 9 , wherein the propellant comprises n-butane, a mixture of n-butane, isobutane and propane, a hydrofluorocarbon or a mixture of any two or more thereof.

11. The composition of claim 1 , wherein the foam adjuvant is selected from one or more of the group consisting of cetyl alcohol, stearyl alcohol, myristyl alcohol, oleyl alcohol, behenyl alcohol, and cetostearyl alcohol.

12. The composition of claim 1 , wherein the foamable carrier further comprises at least one modulating agent selected from the group consisting of a pH adjuster, a buffering agent, a chelator, an antioxidant and an ionization agent a stabilizing agent, and a preservative.

13. The composition of claim 1 , wherein the foamable carrier further comprises a polymeric agent, wherein the polymeric agent is 0.01% to 5% by weight of the foamable carrier and is selected from the group consisting of a bioadhesive agent, a gelling agent, a film forming agent and a phase change agent.

14. The composition of claim 1 , wherein the solvent is at a concentration of not more than or about 40% by weight of the composition.

15. The composition of claim 2 , wherein the active pharmaceutical agent is selected from the group consisting of an anti-infective agent, an antibiotic agent, an antibacterial agent, an antifungal agent, an antiviral agent, an antiparasitic agent, a steroidal anti-inflammatory agent, a nonsteroidal anti-inflammatory agent, an immunosuppressive agent, an immunomodulator, an immunoregulating agent, a hormonal agent, a steroid, a vasoactive agent, a vasoconstructor, a vasodilator, vitamin A, a vitamin A derivative, a retinoid, vitamin B, a vitamin B derivative, vitamin C, a vitamin C derivative, vitamin D, a vitamin D derivative,vitamin E, a vitamin E derivative, vitamin F, a vitamin F derivative, vitamin K, a vitamin K derivative, a wound healing agent, a burn healing agent, a disinfectant, an anesthetic, an antiallergic agent, an alpha hydroxyl acid, lactic acid, glycolic acid, a beta-hydroxy acid, a protein, a peptide, a neuropeptide, an allergen, an immunogenic substance, a haptene, an oxidizing agent, an antioxidant, a dicarboxylic acid, azelaic acid, sebacic acid, adipic acid, fumaric acid, an insectoside, a retinoid, an antiproliferative agent, an anticancer agent, a photodynamic therapy agent, an anti-wrinkle agent, a radical scavenger, a metal oxide, silicone oxide, talc, an anti-acne agent, a skin whitening agent, a self tanning agent, an anti-cellulite agent, a skin protective agent, a masking agent, an anti-wart agent, a refatting agent, a lubricating agent and mixture of any two or more thereof at any proportion; or
