Abstract

Antiperspirant products are described that include a dispensing package and an antiperspirant product contained within a chamber component of the dispensing package. The portion of the chamber component that comes into contact with the antiperspirant composition is made from a polymeric resin that is substantially devoid of phosphorus compounds.

First claim

What is claimed is:

1. An anhydrous antiperspirant product, comprising:
(a) a dispensing package comprising a chamber for holding an antiperspirant composition, the chamber being made from a polyolefin resin that includes an antioxidant that is devoid of phosphorus compounds; and
(b) an antiperspirant composition disposed within the chamber, the antiperspirant composition comprising:
i) a carrier material selected from the group consisting of a volatile silicone, a nonvolatile silicone fluid, and a non-volatile organic fluid;
ii) a particulate antiperspirant active that is an aluminum-zirconium salt and that has a metal to chloride ratio of less than or equal to 1.3; and wherein the finished product comprises the antiperspirant active in particulate form in which the antiperspirant active has a particle size of less than about 125 microns; and
iii) a fragrance material.

2. The antiperspirant product of claim 1 , wherein the polyolefin resin comprises polypropylene.

3. The antiperspirant product of claim 1 , wherein the phosphorus compounds include phosphite.

4. The antiperspirant product of claim 1 , wherein the carrier material includes a silicone.

5. The antiperspirant product of claim 1 , wherein the antiperspirant active has a metal to chloride ratio of between about 1.15 and 1.3.

6. An anhydrous antiperspirant product, comprising:
(a) a dispensing package comprising a chamber for holding an antiperspirant composition, the chamber being made from a polyolefin resin that is devoid of phosphorus compounds; and
(b) an antiperspirant composition disposed within the chamber, the antiperspirant composition comprising:
i) a carrier material selected from the group consisting of a volatile silicone, a nonvolatile silicone fluid, and a non-volatile organic fluid;
ii) a particulate antiperspirant active that is an aluminum-zirconium salt and that has a metal to chloride ratio of less than or equal to 1.3; and wherein the finished product comprises the antiperspirant active in particulate form in which the antiperspirant active has a particle size of less than about 125 microns; and
iii) a fragrance material.

7. The antiperspirant product of claim 6 , wherein the polyolefin resin comprises polypropylene.

8. The antiperspirant product of claim 6 , wherein the phosphorus compounds include phosphite.

9. The antiperspirant product of claim 6 , wherein the carrier material includes a silicone.

10. The antiperspirant product of claim 6 , wherein the antiperspirant active has a metal to chloride ratio of between about 1.15 and 1.3.
