Description

Antiperspirant composition

The present invention relates to antiperspirant compositions.

Antiperspirant ingredients such as aluminum salts and bactericidal ingredients are used in roll-on type and lotion type antiperspirants that use water as a solvent. Furthermore, when adding an oil-based component for the purpose of giving a feeling etc., it is known that emulsifiers, such as nonionic surfactant, are used (for example, refer to patent documents 1).
However, after applying such an antiperspirant to the skin, the solvent water volatilizes to cause the aluminum salt to be whitened on the skin, achieving both the antiperspirant effect and the absence of white remnant on the skin. There was a problem that it was difficult to do.

Therefore, at present, there is a strong demand for the development of an antiperspirant composition capable of suppressing the white remnant of the skin while maintaining the antiperspirant effect.
