ABSTRACT:
An anhydrous, topically-effective composition that resists phase separation and exhibits improved properties comprising a topically-active compound, such as an astringent salt; an improved suspending agent comprising a finely-divided silica and a suspending wax composition; and a suitable volatile liquid carrier, such as a volatile silicone or a volatile hydrocarbon. The suspending wax composition comprises a wax, an ester including at least 10 to about 32 carbon atoms and a volatile liquid carrier. 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.
