Abstract

The present invention is directed to antiperspirant compositions which comprise from about 0.1% to about 99.9% by weight of solubilized or solid antiperspirant active and from about 0.1% to about 99.9% by weight of a carrier which comprises isopropyl glycerol ether, preferably in combination with a volatile silicone liquid carrier and dimethiconol as a coupling agent. The isopropyl glycerol ether carrier is a highly effective coupling agent and is milder to the skin when applied topically to the axilla or other areas of the skin as compared to many other polyol-containing carriers. Preferred are antiperspirant compositions containing solubilized antiperspirant active.

Claims

1. An antiperspirant composition comprising:

A) from about 0.1% to about 99.9% by weight of isopropyl glycerol ether; and

B) from about 0.1% to about 99.9% by weight of an antiperspirant active.

2. The antiperspirant composition of claim 1 wherein the composition comprises from about 0.1% to about 35% by weight of solubilized antiperspirant active.

3. The antiperspirant composition of claim 2 wherein the composition is visibly clear or translucent at 25°

C.

4. The antiperspirant composition of claim 1 wherein the composition comprises from about 0.1% to about 35% by weight of solid antiperspirant active.

5. The antiperspirant composition of claim 1 wherein the composition comprises from about 0.1% to about 70% by weight of isopropyl glycerol ether.

6. The antiperspirant composition of claim 5 wherein the composition comprises from about 1% to about 40% by weight of isopropyl glycerol ether.

7. The antiperspirant composition of claim 5 wherein the composition further comprises from about 1% to about 35% by weight of dimethiconol.

8. The antiperspirant composition of claim 7 wherein the dimethiconol is represented by the formula ##STR5## wherein n is a number having a value of from 0 to about 20.

9. The antiperspirant composition of claim 1 wherein the composition further comprises about 10% to about 90% by weight of a volatile silicone carrier liquid.

10. The antiperspirant composition of claim 9 wherein the composition further comprises a nonvolatile silicone.

11. The antiperspirant composition of claim 1 wherein the composition is anhydrous and contains less than 3% by weight of free or added water.

12. The antiperspirant composition of claim 1 wherein the antiperspirant active is selected from the group consisting of aluminum salts, zirconium salts, and combinations thereof.

13. An antiperspirant composition comprising:

A) from about 0.5% to about 50% by weight of an antiperspirant active;

B) from about 0.1% to about 35% by weight of a suspending or thickening agent; and

C) from about 10% to about 90% by weight of a liquid carrier containing isopropyl glycerol ether.

14. The antiperspirant composition of claim 13 wherein the composition comprises from about 0.5% to about 25% by weight of solubilized antiperspirant active.

15. The antiperspirant composition of claim 13 wherein the composition comprises from about 0.5% to about 35% by weight of solid antiperspirant active.
