Non-water-containing stick-type antiperspirant

Abstract

The object of the present invention is to provide a non-water-containing stick-type antiperspirant that contains calcined alum particles as an antiperspirant ingredient, provides a consistent feeling of use from the beginning to the end of use, and has excellent stability as an antiperspirant. [Solution] To solve the above problems, the present invention provides a non-aqueous stick-type antiperspirant containing calcined alum particles and a solidifying agent, wherein the solidifying agent consists of an oily component that is solid at room temperature and contains 50% by mass or more of hydrocarbon wax. According to the present invention, deformation and deterioration due to moisture absorption can be prevented, allowing non-water-containing stick-type antiperspirants to provide the same feeling of use from the beginning to the end of use, while also improving the stability of the antiperspirant.
