Description

The present invention relates to a liquid cosmetic composition and a sheet-like cosmetic.

Due to the intense heat of recent years, there is a demand for sheet-shaped cosmetics for antiperspirant that have a high refreshing sensation. However, there is a problem that silica, which is a tactile-imparting agent, aggregates in a sheet-like cosmetic containing 0.5% by mass or more of a menthol-based refreshing agent.

Conventionally, a sheet that suppresses the aggregation of silica by impregnating a hydrophilic inorganic powder such as silica and a menthol-based refreshing agent of 0.5% by mass or more with a specific polyoxyethylene alkyl ether as a surfactant. Menthol has been proposed (see Patent Document 1). However, in the sheet-shaped cosmetics of this proposal, there is a problem that the use of polyoxyethylene alkyl ether causes the impregnating liquid to feel sticky when it dries, and the feeling of use immediately after use is deteriorated.

Therefore, it is possible to suppress the aggregation of silica, it is not irritating to the skin, it is excellent in refreshing feeling, smooth feeling of the skin after use, non-stickiness of the skin after use, and no dryness of the skin after use, and it is in the form of a sheet.
