Claims
- 1. An aerosol antiperspirant composition comprising:
- (a) from about 2% to about 10% of a hydrophobic liquid selected from the group consisting of fatty acid and fatty alcohol esters, water-insoluble ethers and alcohols, polyorganosilicones, and mixtures thereof;
- (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.
- 2. An antiperspirant composition according to claim 1, wherein said activator is propylene carbonate.
- 3. An antiperspirant composition according to claim 1, wherein said suspension agent is a hectorite clay and said activator is present at a level of from about 0.04% to about 0.06%.
- 4. An antiperspirant composition according to claim 2, wherein said enhanced efficacy metallic antiperspirant material is an enhanced efficacy aluminum chlorhydrate.
- 5. An antiperspirant composition according to claim 4, wherein said enhanced efficacy aluminum chlorhydrate contains at least about 40% (by weight of all aluminum species in said aluminum chlorhydrate) of the preferred metallic species.
- 6. An antiperspirant composition according to claim 5 wherein said suspending agent is a bentonite clay.
- 7. An antiperspirant composition according to claim 5, wherein said enhanced efficacy aluminum chlorhydrate contains less than about 1% (by weight of all aluminum species in said aluminum chlorhydrate) of the first aluminum fraction isolated in size exclusion chromatography of said aluminum chlorhydrate.
- 8. An antiperspirant composition according to claim 2, wherein said enhanced efficacy aluminum chlorhydrate is an enhanced efficacy zirconium-aluminum complex.
- 9. An antiperspirant suspension composition according to claim 2, wherein said hydrophobic liquid carrier comprises said polyorganosilicone.
- 10. A method for making an aerosol antiperspirant composition according to claim 1, for delivery from a suitable aerosol container, comprising the steps of:
- (a) preparing a concentrate by mixing and milling said hydrophobic liquid carrier, said activator and said clay suspending agent; and adding said enhanced efficacy antiperspirant material to the mixture of said materials either before or after said milling;
- (b) filling said concentrate into said container; and
- (c) pressurizing said container by adding said suitable aerosol propellant into said container and sealing said container.
