Description

The present invention relates to an oily composition containing an antiperspirant component such as potassium aluminum sulfate, and more particularly to an oily composition having excellent redispersibility of the antiperspirant component.

As an antiperspirant component that reduces the amount of perspiration, potassium aluminum sulfate (alum), dried potassium aluminum sulfate (alum alum), aluminum hydroxychloride, and the like are known. These antiperspirant components are used in antiperspirants such as sprays and lotion types because they reduce the amount of perspiration by obstructing or astringent the sweat glands.

In addition to the antiperspirant component, antiperspirant components such as antiperspirant components are also used to suppress the growth of microorganisms that oxidize and decompose secretions from sweat glands and generate odors. When combined with a specific inorganic antibacterial ingredient, discoloration occurs when it adheres to clothing. On the other hand, a technique for preventing discoloration by blending zinc oxide is disclosed (Patent Document 1).

However, although the use of zinc oxide does prevent discoloration when it adheres to clothes, alum and metal oxides aggregate over time, forming aggregates that are difficult to redisperse even when shaken. It became difficult to apply alum and metal oxides uniformly, and as a result, there was a problem that sufficient antiperspirant effect and sunscreen effect could not be obtained.
