Description

  The present invention relates to fluid-based sweat deodorant compositions.

  Conventionally, many deodorant compositions have been developed in order to suppress the generation of body odor such as odor and foot odor. The deodorant composition contains an antiperspirant component, a deodorant component, a bactericidal component and the like in order to suppress the generation of body odor. As the antiperspirant component, for example, chlorhydroxyaluminum which is an aluminum compound is widely used (see, for example, Patent Documents 1 and 2). However, although the deodorant composition containing chlorhydroxyaluminum is excellent in antiperspirant effect, it has problems such as white residue on the skin immediately after application and stickiness of the skin.

  In order to solve these problems, for example, an antiperspirant deodorant spray in which silicone oil is blended and the skin is not sticky and has no white residue on the skin has been proposed (for example, see Patent Document 3). However, this proposal, while maintaining the antiperspirant effect, has no residual whiteness on the skin immediately after application, no stickiness of the skin, and insufficient durability of the deodorizing effect, and further improvement and development is desirable. It is rare.

  Therefore, it is desired to provide a liquid system sweat deodorant composition that is excellent in antiperspirant effect and has no white residue on the skin immediately after application, non-stickiness of the skin, and durability of deodorizing effect.

Ethanol mass% = volume% × 0.79422 (specific gravity of 100% by volume at 15 ° C.) / D (specific gravity at 15 ° C.) Formula 1
= (95 x 0.79422) /0.81639
= 92.42
