Abstract

An aerosol antiperspirant composition is provided. The aerosol antiperspirant composition includes a propellant having a concentration from 70% to 90% by weight of the aerosol antiperspirant composition and an antiperspirant composition. The antiperspirant composition includes one or more liquid materials, wherein the one or more liquid materials comprise one or more non-volatile silicone fluids having a concentration from 40% to about 70% by weight of the antiperspirant composition, an antiperspirant active particulate, one or more non-antiperspirant active particulates that are substantially inert, wherein the one or more non-antiperspirant active particulates have a concentration from 10% to 30% by weight of the antiperspirant composition. The antiperspirant composition has a total particulate concentration from 30% to about 60% by weight of the antiperspirant composition.

First claim

What is claimed is:

1. An aerosol antiperspirant composition, comprising:
a propellant having a concentration from 70% to 95%, by weight of the aerosol antiperspirant composition;
an antiperspirant composition comprising:
one or more liquid materials comprising 70% to 100% by weight of the liquid materials, of non-volatile polydimethyl siloxane fluid; the one or more liquid materials having a concentration from 40% to 70% by weight of the antiperspirant composition;
an antiperspirant active particulate;
one or more non-antiperspirant active particulates that are substantially inert, having a concentration from 1% to 25%, by weight of the antiperspirant composition.

2. The aerosol antiperspirant composition according to claim 1 , wherein the one or more liquid materials of the antiperspirant composition consist essentially of one or more non-volatile polydimethyl siloxane fluid.

3. The aerosol antiperspirant composition according to claim 2 , further comprising a particulate fragrance material having a concentration from 0.25% to 5% by weight of the antiperspirant composition.

4. The aerosol antiperspirant composition according to claim 1 , wherein the antiperspirant active particulates have a concentration from 16% to 32%, by weight of the antiperspirant composition.

5. The aerosol antiperspirant composition according to claim 1 , further comprising a liquid fragrance material having a concentration less than 4% by weight of the antiperspirant composition.

6. The aerosol antiperspirant composition according to claim 1 , wherein the antiperspirant composition further comprises a silicone gum having a concentration from 0.1% to 1.5%, by weight of the antiperspirant composition.

7. The aerosol antiperspirant composition according to claim 1 , wherein the antiperspirant composition further comprises a total particulate material and a ratio of the concentration of the total liquid material to the concentration of the total particulate material from 0.6 to 1.6.

8. The aerosol antiperspirant composition according to claim 1 , wherein the liquid materials comprise less than 10% by weight of volatile silicone fluids.

9. The aerosol antiperspirant composition according to claim 7 , wherein the antiperspirant composition is substantially free of volatile silicone fluids.

10. The aerosol antiperspirant composition according to claim 1 , wherein the non-antiperspirant active particulates are selected from the group consisting of particulate fragrance materials, native starches, hydrophobically modified starches and combinations thereof.

11. The aerosol antiperspirant composition according to claim 1 , wherein the antiperspirant composition has a viscosity greater than 3,000 centipoises.

12. The aerosol antiperspirant composition according to claim 1 , wherein the antiperspirant composition is substantially free of quartenary ammonium functional silicones.

13. The aerosol antiperspirant composition according to claim 1 , wherein the antiperspirant composition is substantially free of functionalized siloxanes capable of reacting with the antiperspirant active particulates via an acid base or chelation reaction.

14. The aerosol antiperspirant composition according to claim 1 , wherein the antiperspirant composition further comprises a total particulate material and a ratio of the concentration of the antiperspirant active particulate to the concentration of the total particulate from 0.1 to 0.75.

15. The aerosol antiperspirant composition according to claim 1 , wherein the non-volatile siloxane fluids consist essentially of a polydimethyl siloxane fluid having a viscosity of 5 centistokes to 350 centistokes.

16. A product, comprising a reservoir, an actuator comprising an actuator orifice, and a valve in fluid communication with the actuator orifice and the reservoir, the reservoir storing an aerosol antiperspirant composition according to claim 1 .
