Description

Liquid sweating composition

The present application claims priority from Japanese Patent Application No. 2012-210843, filed on Sep. 25, 2012.

The present invention relates to a composition for liquid sweating, and more particularly to a composition for liquid sweating which is excellent in cooling feeling and stability.

In the season when the temperature is high, the composition for sweating has many opportunities. Therefore, it is required to have a composition for sweating which not only has a sweating effect but also gives a refreshing feeling such as a cold feeling.

In the case of such a composition for sweating, Patent Document 1 discloses a cold feeling deodorant cosmetic formulated with a cold feeling substance such as menthol or a sweating agent such as zinc phenolsulfonate.

Further, Patent Document 2 discloses that a cold-sensitive substance such as L-menthol and a cationic surfactant such as a two-chain type cationic surfactant are blended to improve the cold feeling effect.

On the other hand, when a two-chain type cationic surfactant and a pair of p-phenol sulfonate are used in combination, even if the amount of these is small, the composition will produce white precipitates and have a problem of stability.

Before explaining the embodiment, the evaluation method of the stability used in the present invention will be described.

‧ Stability assessment method

The stability of the sample after storage at -5 ° C or 0 ° C or 5 ° C or 10 ° C or 25 ° C for 1 week was evaluated.

◎: No white precipitates were produced, and the whole was transparent.

○: Almost no white precipitate was produced.

△: A white precipitate was slightly generated.

×: White precipitates were produced as a whole.

By combining menthol or a derivative thereof with a di-long-chain cationic surfactant, a composition excellent in cooling feeling can be obtained. Here, the composition for sweating in combination with the compound and the zinc phenolsulfonate having a sweating effect is examined. discuss.
