Abstract
Stable, two phase antiperspirant stick compositions having (1) a substantially anhydrous antiperspirant phase comprising a water-insoluble, high melting point wax, a liquid emollient, and high levels of a particulate, antiperspirant active material and (2) a gel phase comprising a polyhydric alcohol gelled with either a fatty acid soap or a fatty acid amide. Such antiperspirant sticks provide effective antiperspirancy performance as well as desirable application characteristics.
Claims10
An antiperspirant composition in the form of a two-phase stick, said composition comprising:
- (A) from about 40 to 60% by weight of the composition of a solid, substantially anhydrous antiperspirant phase comprising
- I. from about 8 to about 15% by weight of the antiperspirant phase of a water-insoluble high melting wax which has a melting point of from about 150.degree. F. to about 215.degree. F.
- Ii. from about 20 to about 50% by weight of the antiperspirant phase of a water-insoluble liquid, organic, non-hydrocarbon emollient;
- and
- Iii. from about 30 to about 60% by weight of the antiperspirant phase of a solid particulate astringent antiperspirant material;
- and,
- (B) from about 40 to 60% by weight of the composition of a gel phase contiguous to said solid antiperspirant phase, said gel phase comprising
- I. from about 10 to 92% by weight of the gel phase of a polyhydric aliphatic alcohol containing from 2 to 4 carbon atoms and from 2 to 3 hydroxy groups;
- and
- Ii. from about 5 to 15% by weight of the gel phase of a gel forming agent selected from the group consisting of sodium salt of a fatty acid containing from 14 to about 22 carbon atoms and potassium salt of a fatty acid containing from about 14 to about 22 carbon atoms.
