An anhydrous, topically-effective composition that resists phase separation and exhibits improved sensory properties comprising a topically-active compound, such as an astringent salt; a finely-divided silica; a suspending wax composition; and a suitable volatile liquid carrier vehicle, such as a volatile silicone or a volatile hydrocarbon. The anhydrous, topically-effective composition is useful in topical cosmetic and medicinal preparations, such as antiperspirants, sunscreens and topical drug products, and is especially useful in cosmetic and medicinal preparations wherein an insoluble topically-active compound is dispersed throughout a liquid phase. |
