Problems solved by technology

Shaving foams, by definition, are not breakable and thus not conducive to topical administration of active ingredients, especially for topical administration of skin penetrating compositions

Embodiment 1

[0214] Example 1 - Production of Pharmaceutical or Cosmetic Foam Carriers and Compositions - General Method

[0215] A method of preparing a pharmaceutical foam carrier generally includes the following steps.

[0216] Step 1 - Water phase: Dissolve gelling agent and surfactant in water while stirring. The solution was warmed to 50-70°C. Add the water-soluble cosmetic or pharmaceutical active ingredient* and optional water-soluble ingredients to the aqueous mixture while stirring.

[0217] Step 2 - Hydrophobic phase: Heat the hydrophobic solvent to the same temperature. Add the oil-soluble cosmetic or pharmaceutical active ingredient* and optional oil-soluble formulation ingredients to the hydrophobic phase mixture while stirring.

[0218] Step 3 - Gradually pour the warm hydrophobic phase into the warm aqueous phase while stirring, followed by homogenization with Ultraturax. The mixture was allowed to cool to ambient temperature.

[0219] Step 4 - Add the mixture to an ae...

Abstract

The invention relates to an alcohol-free cosmetic or pharmaceutical foam carrier comprising water, a hydrophobic solvent, a surface-active agent and a gelling agent. The foam carrier further comprises active agents and excipients with therapeutic properties having enhanced skin penetration.

Description

field of invention [0001] The present invention relates to an alcohol-free cosmetic or pharmaceutical foam carrier comprising water, a hydrophobic solvent, a surfactant and a gelling agent. The foam carrier further comprises active agents and excipients that provide beneficial therapeutic properties. Background of the invention [0002] Foam products are used for topical application of drugs and cosmetics. Aerosol products, especially foams, have complex physico-chemical structures that do not form under arbitrary circumstances. Precisely, a special balance between the foam-forming components is important. Slight shifts in composition may have led to foam collapse; thus, formulations of per se active substances may not be formulated as foams without further preparation. [0003] The inventors of the present invention have developed a series of novel emulsion-based foam formulations. See eg commonly assigned co-pending application WO 2004 / 037225. [0004] US Patent No. 6...
