- (b) from about 20% to about 95% of a propellant;
- (c) from about 2% to about 30% of an enhanced efficacy metallic antiperspirant material containing at least about 30% of a high efficacy metallic species (by weight of all metallic species in said antiperspirant material);
- (d) from about 0.1% to about 3.0% of a hydrophobically-treated bentonite or hectorite clay suspension agent;
- and
- (e) an activator selected from the group consisting of propylene carbonate, ethanol, and mixtures thereof, wherein the level of activator is from about 0.01% to about 0.195% when the suspension agent is said hectorite clay and from about 0.01% to about 0.03%, when the suspension agent is a bentonite clay.
