Abstract
Abstract Antiperspirant stick compositions comprising: (a) from about 35% to about 60% of a volatile silicone oil; (b) from about 1% to about 5% of a non-volatile emollient; (c) from about 2.5% to about 4% of a high melting point wax; (d) from about 10% to about 15% of a low melting point wax; (e) from about 0.2% to about 1.5% of a colloidal silica material; (f) from about 0.5% to about 4% of an inert spherical particulate material which is comprised of essentially spherical particles having a mean diameter of at least about 10 microns; (g) from about 2% to about 9% of a talcum material; and (h) from about 20% to about 33% of a particulate antiperspirant material; wherein the total level of talcum material and antiperspirant material is from about 25% to about 35%.
