Abstract:
1. A hydrating foamable composition comprising an emulsion, the emulsion comprising: i. a hydrating component comprising lanolin, wherein the lanolin is present in an amount of at least about 5% by weight of the composition emulsion; ii. about 0.1% to about 5% of a non-ionic surface-active agent by weight of the composition emulsion; iii. about 0.01% to about 5% by weight of the emulsion of at least one polymeric additive selected from the group consisting of a bioadhesive agent, a gelling agent, a film forming agent˜and a phase change agent; iv. water; and v. at least one therapeutic agent selected from the group consisting of an anti-infective, an antibiotic, an antibacterial agent, an antifungal agent, an antiviral agent, an antiparasitic agent, a steroidal antiinflammatory agent, an immunosuppressive agent, an immunomodulator, an immunoregulating agent, a hormonal agent, a vitamin A, a vitamin A derivative, a vitamin B, a vitamin B derivative, a vitamin C, a vitamin C derivative, a vitamin D, a vitamin D derivative, a vitamin E, a vitamin E derivative, a vitamin F, a vitamin F derivative, a vitamin K, a vitamin K derivative, a wound 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, a allergen, an immunogenic substance, a haptene, an oxidizing agent, an antioxidant, a dicarboxylic acid, azelaic acid, sebacic acid, adipic acid, fumaric acid, a retinoid, an antiproliferative agent, an anticancer agent, a photodynamic therapy agent, benzo1 chloride, calcium hypochlorite, magnesium hypochlorite, an anti-wrinkle agent, a radical scavenger, a metal, silver, a metal oxide, titanium dioxide, zinc oxide, zirconium oxide, iron oxide, silicone oxide, talc, carbon, a skin whitening agent, a skin protective agent, a masking agent, an anti-wart agent, a refatting agent, a lubricating agent, and mixtures of two or more thereof; and a liquefied or compressed gas propellant at a concentration of about 3% to about 25% by weight of the total composition; wherein the composition is free of ionic surface active agents; and wherein upon release from a pressurized container the composition expands to form a breakable foam that is thermally stable and collapses upon application of shear force.
