Description

The present invention relates to a transparent liquid cleansing cosmetic.

Cleansing cosmetics can be roughly classified into oil-based cleansing cosmetics and water-based cleansing cosmetics. Since oily cleansing cosmetics contain a large amount of oily components, they are well compatible with make-up stains and exhibit excellent cleansing power. On the other hand, there are drawbacks such as reattachment of make-up stains that have once come to the surface on the skin, and a sticky feeling peculiar to oily ingredients remains on the skin after cleansing, resulting in a poor usability.

On the other hand, water-based cleansing cosmetics contain a small amount of oily components, so while they provide a refreshing feel, they have the drawback of poor compatibility with makeup stains and poor cleansing power. .

Therefore, in recent years, cleansing cosmetics that form a bicontinuous microemulsion structure in which an oil phase and a water phase form a continuous phase, which are said to have a high cleansing effect despite a low oily feel during use. A number of materials have been proposed (see, for example, Patent Documents 1 to 4).

However, cleansing cosmetics having a bicontinuous microemulsion structure are required to be further improved in feel during use. A cleansing cosmetic having a bicontinuous microemulsion structure containing an oily component gives a slightly oily feeling to the skin after use, and it is difficult to obtain a refreshing feeling after use, and furthermore, the skin feels tight after use. occurs. In addition, there is a strong demand for a cleansing cosmetic that is excellent in low irritation, since there is a possibility that the skin may be irritated by oily components and surfactants.
