Abstract

An aerosol antiperspirant composition is provided. The aerosol antiperspirant composition includes a propellant having a concentration from 30% to 65% by weight 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; antiperspirant active particulates; one or more non-antiperspirant active particulates that are substantially inert; and wherein the antiperspirant composition has a total particulate concentration from 30% to about 60% by weight and the antiperspirant composition has a viscosity greater than 1,000 centipoise.

Claims (25)

1. An aerosol antiperspirant composition, comprising:

a liquid propellant having a concentration from 30% to 65% by weight of 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;

antiperspirant active particulates;

wherein the antiperspirant composition has a L/P ratio of from about 0.6 to about 1.6, an A/P ratio of from about 0.1 to about 0.95, and a viscosity from 1,000 centipoise to about 50,000 centipoise.

2. The aerosol antiperspirant composition of claim 1 , wherein the antiperspirant composition is in the form of a dispersion.

3. An aerosol antiperspirant composition according to claim 1 , wherein the one or more liquid materials of the antiperspirant composition consist essentially of non-volatile polydimethyl siloxane fluid, a liquid fragrance material and silicone gum.

4. An aerosol antiperspirant composition according to claim 1 , further comprising a particulate fragrance material having a concentration from about 0.25% to about 5% by weight of the antiperspirant composition.

5. An 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. An aerosol antiperspirant composition according to claim 1 , wherein the non-volatile silicone fluids have a concentration from about 40% to 55% by weight of the antiperspirant composition.

7. An aerosol antiperspirant composition according to claim 1 , wherein the antiperspirant composition has a total particulate concentration from 30% to 60% by weight of the antiperspirant composition.

8. An aerosol antiperspirant composition according to claim 1 , wherein the antiperspirant composition is substantially or completely free of a silicone gum.

9. An aerosol antiperspirant composition according to claim 1 , wherein the L/P ratio is from about 0.6 to about 1.4.

10. An aerosol antiperspirant composition according to claim 1 , wherein the non-volatile polydimethyl siloxane fluid consists essentially of a polydimethyl siloxane fluid having a viscosity of 5 centistokes to 350 centistokes.

11. An aerosol antiperspirant composition according to claim 1 , wherein the one or more liquid materials comprise less than 10% by weight of volatile silicone fluids.

12. An aerosol antiperspirant composition according to claim 1 , wherein the antiperspirant composition is substantially or completely free of volatile silicone fluids.

13. An aerosol antiperspirant composition according to claim 1 , wherein the particulates of the antiperspirant active have a concentration less than 34% by weight of the antiperspirant composition.

14. An aerosol antiperspirant composition according to claim 1 , further comprising one or more bulking or suspending materials selected from the group consisting of a silica material, a clay material and combinations thereof.

15. An aerosol antiperspirant composition according to claim 1 , further comprising one or more non-antiperspirant active particulates selected from the group consisting of particulate fragrance materials, native starches and combinations thereof.

16. An aerosol antiperspirant composition according to claim 1 , wherein the antiperspirant composition has a viscosity from 3,000 centipoises to 40,000 centipoises.

17. An aerosol antiperspirant composition according to claim 1 , wherein the liquid propellant has a concentration from about 50% to 65% by weight of the aerosol antiperspirant composition.

18. An aerosol antiperspirant composition according to claim 1 , wherein the A/P ratio is from 0.3 to 0.75.

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

20. A method of using the product of claim 19 , wherein the antiperspirant composition is sprayed onto an axillia surface.
