Description

Deodorant composition

The present invention relates to a deodorant composition.

In recent years, an increasing number of people feel anxious about their body odor, and antiperspirants are required to have a higher body odor suppression effect. In order to suppress body odor, it is very effective to suppress sweat, which is an odor-causing substance. Many of the antiperspirants currently on the market use the sweat gland occlusion action by chlorohydroxyaluminum as a technique for suppressing perspiration.
However, when the amount of sweating is large, the antiperspirant effect is not sufficient, and there are many complaints that the smell is worrisome.

In addition, the following are mentioned as prior art documents relevant to the present invention.
