Abstract
Solid stick antiperspirant compositions include an antiperspirant active, one or more waxes, and a plurality of liquids. The one or more waxes include a polar wax. The plurality of liquids include about 60% or greater, by weight of the plurality of liquids, of a non-volatile silicone. The solid stick antiperspirant composition is substantially or completely free of volatile silicones. Antiperspirant product containing solid stick antiperspirant compositions are also described herein.
Claims21
A solid stick antiperspirant composition comprising:
- a. an antiperspirant active;
- b. one or more waxes comprising a polar wax;
- and
- c. a plurality of liquids comprising a first emollient and a second emollient, wherein the first emollient comprises polydimethylsiloxane, the polydimethylsiloxane having a viscosity of about 2 to about 6 centistokes and being present at about 60% or greater, by weight, of the plurality of liquids and the second emollient is present at about 16% to about 40%, by weight, of the plurality of liquids, and wherein the plurality of liquids are a homogeneous mixture and have an aggregate polarity from about 0.9 MPa1/2 to about 3.4 MPa1/2;
- d. wherein the solid stick antiperspirant composition is free of volatile silicones;
- and wherein the second emollient is selected from the group consisting of C12-15 alkyl benzoate, isopropyl myristate, isopropyl palmitate, and octyldodecanol.
