Stable, clear, antiperspirant microemulsions containing cosmetic oils, antiperspirant salts, and water and combinations of cationic quaternary ammonium salt are provided. These microemulsions can be used in different types of applicators such as roll-on, sponge, mousse, pad, brush, gel and aerosol or non-aerosol spray applicators.

Antiperspirant compositions comprising microemulsions

Rinse-off, water-in-oil-in-water multiple emulsion compositions are disclosed. The multiple emulsion compositions comprise an external aqueous phase optionally incorporating an emulsifier and/or a second topically-active compound. The internal phase comprises a primary water-in-oil emulsion, wherein the primary emulsion comprises a first topically-active compound, a surfactant phase, an oil phase, and water.

Rinse-off water-in-oil-in-water compositions

Non-ionic surfactant emulsion vehicles and compositions comprising an emulsifier system including one or more non-ionic surfactants, an oil phase and an aqueous phase for enhancing the penetration of a drug substance across the stratum corneum and into deeper skin layers are disclosed. A method whereby an effective amount of a composition comprising the emulsion vehicle and a drug substance is topically applied to the skin also is disclosed.

Non-ionic surfactant emulsion vehicles and their use for deposition of

Water-in-oil-in-water multiple emulsion compositions are disclosed. The multiple emulsion compositions comprise an external aqueous phase optionally incorporating a surfactant system capable of forming liquid crystals as an emulsifier. The internal phase comprises a primary water-in-oil emulsion, wherein the primary emulsion comprises a first topically-active compound, a surfactant phase, an oil phase, and water.
