Abstract

A solid stick antiperspirant composition is provided. The antiperspirant composition includes aluminum zirconium tetrachlorohydrex glycine having a concentration from about 10% to about 35% by weight of the composition, an anhydrous liquid carrier, one or more structurants having a concentration from about 15% to about 25% by weight of the composition, wherein the one or more structurants comprises one or more waxes and a non-ionic exthoxylated linear alcohol having a carbon chain length from about 20 to about 40. The solid stick antiperspirant composition is a single phase.

First claim

What is claimed is:

1. A solid stick antiperspirant composition, comprising:
an antiperspirant active selected from the group consisting of aluminum zirconium tetrachlorohydrex and aluminum zirconium trichlorohydrex, wherein the antiperspirant active has a concentration from 10% to about 35% by weight of the composition;
one or more anhydrous liquid carriers;
one or more structurants having a concentration from about 15% to about 25% by weight of the composition, wherein the one or more structurants comprises from about 10% to about 20%, by weight of the composition, of stearyl alcohol;
a non-ionic ethoxylated linear alcohol having a carbon chain length from about 20 to about 40; and
wherein the solid stick antiperspirant composition is a single phase.

2. The antiperspirant solid stick composition of claim 1 , wherein the antiperspirant composition has a Red Dot Color Value of 0.4 or less at 2, 3, 4, 5, 10 and 15 minutes and a Red Dot Color Value greater than 1 at 30 seconds and a Red Dot Color Value of 1.25 or more at 24 hours.

3. The antiperspirant solid stick composition of claim 2 , wherein the antiperspirant composition has a 24 hour diameter between about 2 and about 3.5 cm.

4. The antiperspirant solid stick composition of claim 1 , wherein the non-ionic ethoxylated linear alcohol has an HLB value between about 6 and about 12.

5. The antiperspirant solid stick composition of claim 1 , wherein the antiperspirant solid stick composition is anhydrous and has a hardness equal to or greater than 600 gram force.

6. The antiperspirant solid stick composition of claim 1 , wherein the non-ionic ethoxylated linear alcohol has a concentration from about 1% to about 4% by weight of the antiperspirant composition.

7. The antiperspirant solid stick composition of claim 1 , wherein at least one of the one or more structurants is selected from the group consisting of alcohol, hydrogenated castor wax, ozokerite, behenyl alcohol, polyethylene, polymethylene, and a triglyceride.

8. The antiperspirant solid stick composition of claim 1 , wherein the one or more anhydrous liquid carriers comprises a non-volatile silicone fluid.

9. The antiperspirant solid stick composition of claim 1 , wherein the antiperspirant active is aluminum tetrachlorohydrex glycine.

10. An antiperspirant product, comprising a canister and the solid stick antiperspirant composition according to claim 1 disposed within the canister.

11. An antiperspirant solid stick composition, comprising:
an antiperspirant active comprising a zirconium containing salt and having a concentration from about 10% to about 35% by weight of the composition;
one or more anhydrous liquid carriers;
one or more structurants having a concentration from about 15% to about 25% by weight of the composition, wherein the one or more structurants comprises from about 10% to about 20%, by weight of the composition, of stearyl alcohol;
a non-ionic ethoxylated linear alcohol; and
wherein the antiperspirant composition has a Red Dot Color Value of 0.5 or less at 2, 3, 4, 5, 10 and 15 minutes and a Red Dot Color Value greater than 1 at 30 seconds and a Red Dot Color Value of 1.25 or more at 24 hours.

12. The solid stick antiperspirant composition of claim 11 , wherein the non-ionic ethoxylated linear alcohol has an HLB value between about 6 and about 12.

13. The solid stick antiperspirant composition of claim 11 , wherein the non-ionic ethoxylated linear alcohol has a carbon chain length from about 20 to about 40.

14. The solid stick antiperspirant composition of claim 11 , wherein the antiperspirant active further comprises glycine.

15. The solid stick antiperspirant composition of claim 11 , wherein the antiperspirant active is aluminum zirconium trichlorohydrex or aluminum zirconium tetrachlorohydrex.

16. The solid stick antiperspirant composition of claim 11 , wherein at least one of the one more structurants is selected from the group consisting of hydrogenated castor wax, ozokerite, behenyl alcohol, polyethylene, polymethylene, and a triglyceride.

17. The solid stick antiperspirant composition of claim 11 , wherein the non-ionic ethoxylated linear alcohol has a concentration from about 1% to about 4% by weight of the antiperspirant composition.

18. A solid stick antiperspirant composition, comprising:
an antiperspirant active comprising a zirconium containing salt and having a concentration from about 10% to about 35% by weight of the composition;
one or more anhydrous liquid carriers;
one or more structurants having a concentration from about 15% to about 25% by weight of the composition, wherein the one or more structurants comprises from about 10% to about 20%, by weight of the composition, of stearyl alcohol;
a non-ionic ethoxylated linear alcohol having a carbon chain length from about 20 to about 40 and an HLB value between about 6 and about 12; and
wherein the solid stick antiperspirant composition is a single phase.

19. The antiperspirant solid stick composition of claim 18 , wherein the antiperspirant is aluminum zirconium tetrachlorohydrex or aluminum zirconium trichlorohydrex.

20. The antiperspirant solid stick composition of claim 18 , wherein the antiperspirant composition has a Red Dot Color Value of 0.4 or less at 2, 3, 4, 5, 10 and 15 minutes and a Red Dot Color Value greater than 1 at 30 seconds and a Red Dot Color Value of 1.25 or more at 24 hours.
