Abstract
Cosmetic stick compositions comprising one or more liquid base materials, one or more solidfying agents for the liquid base materials, and from about 2% to about 30% (by total composition volume) of chemically inert particulates of at least 10 microns in diameter and having a density less than about 0.60 g/ml. The liquid base materials are typically present at a level of from about 10% to about 90% (by total composition weight), and the solidifying agent is typically present at a level of from about 3% to about 70% (by total composition weight). These cosmetic sticks may be of a gel stick type or a wax stick type, depending upon the particular liquid base materials and solidifying agents used. Preferred cosmetic sticks contain a safe and effective amount of an active material having, for example, antiperspirant or deodorant activity.

A cosmetic stick composition, comprising:
- (a) one or more liquid base materials;
- (b) a solidifying agent of a type and amount effective to solidify said liquid base materials;
- and
- (c) from about 2% to about 30% (by volume) of chemically inert particulates of at least about 10 microns in diameter and having a density less than about 0.60 g/ml.
A cosmetic stick composition, in gel form, comprising:
- (a) from about 15% to about 30% (by weight) of polyhydric alcohol;
- (b) from about 3% to about 10% (by weight) of a soap;
- and
- (c) from about 3% to about 20% (by volume) of chemically inert particulates, of from about 15 to 75 microns in diameter, having a density of from about 0.02 to 0.50 g/ml.
A cosmetic stick composition in wax form, comprising:
- (a) from about 10% to about 65% (by weight) of one or more volatile silicone oils;
- (b) from about 10% to about 70% (by weight) of one or more materials having wax-like characteristics;
- and
- (c) from about 3% to about 20% (by volume) of chemically inert particulates, of from about 15 to 75 microns in diameter, having a density of from about 0.02 to about 0.50 g/ml.
