Abstract
Abstract Antiperspirant cream compositions, which exhibit reduced residue on the skin and excellent cosmetics and aesthetics, as well as good composition stability over time, are claimed. These compositions, which may be formulated to have relatively high viscosities, include a volatile silicone material, a particulate antiperspirant active, a clay thickening agent, an activator for the clay thickening agent, and a non-volatile paraffinic hydrocarbon fluid, such as mineral oil or branched chain C 16 -C 68 hydrocarbons. A method of treating or preventing perspiration in humans using these compositions is also claimed.
