Embodiment

[0071] Regarding the present invention, examples are given below to further describe in detail, but the present invention is not limited thereto. Unless otherwise specified, the compounding amount is expressed in mass % with respect to the system in which the component is compounded.

[0072] Before describing the examples, the stability evaluation method used in the present invention will be described.

[0073] ?Stability evaluation method

[0074] The stability of the samples stored at -5°C, 0°C, 5°C, 10°C, or 25°C for 1 week was evaluated.

[0075] ⊚: No white precipitates were generated, and the whole had a sense of transparency.

[0076] ◯: Almost no white precipitates were generated.

[0077] Δ: A small amount of white precipitate was generated.

[0078] ×: A white precipitate is generated as a whole.

[0079] Combining menthol or a derivative thereof with a di-long-chain type cationic surfactant can provide a composition excellent in refreshing feeling. Therefore,...

Abstract

The present invention provides a liquid antiperspirant composition having an excellent sensation of coolness and excellent stability. The liquid antiperspirant composition according to the present invention is characterized by comprising components (a) to (e) as mentioned below, wherein the amount of the component (d) added is less than 70 mass%: (a) menthol or a derivative thereof; (b) a di-long-chain-type cationic surfactant; (c) zinc paraphenolsulfonate; (d) ethanol; and (e) a clay mineral.

Description

[0001] related application [0002] This application claims the priority of Japanese Patent Application No. 2012-210843 for which it applied on September 25, 2012, and uses it here. technical field [0003] The present invention relates to a liquid antiperspirant composition, and particularly relates to a liquid antiperspirant composition excellent in cooling feeling and stability. Background technique [0004] Antiperspirant compositions are often used in seasons when the temperature is high. Therefore, there is a demand for an antiperspirant composition that imparts not only an antiperspirant effect but also a refreshing feeling such as a cooling sensation. [0005] As an example of such an antiperspirant composition, Patent Document 1 discloses a cool deodorant cosmetic containing a cooling substance such as menthol and an antiperspirant such as zinc p-phenolsulfonate. [0006] In addition, Patent Document 2 describes that the cooling effect is improved by blending a co...
