2. Description of the Related Art In cosmetics obtained by using one or more of polyacrylic acid represented by carboxyvinyl polymer and derivatives thereof, an oil phase raw material is transparent or translucent without using a surfactant. In many cases, there are restrictions such as the fact that the addition amount must be extremely small.

Further, as a method of transparently blending an oil used in cosmetics into a preparation, there are a method of solubilizing with an surfactant and a liquid crystal structure composition comprising a hydrophilic nonionic surfactant. Of these, the method of solubilizing with a surfactant is used for cosmetics such as beauty liquids and lotions. On the other hand, a liquid crystal structure composition composed of a hydrophilic nonionic surfactant is used especially for cleansing-type cleansing cosmetics and massage cosmetics.

However, these transparent techniques are
There was a drawback in that it was sometimes restricted in the application field. For example, the method of solubilizing with a surfactant has the drawbacks that the amount of oil that can be clarified is small and that a large amount of surfactant is required. Further, there are restrictions on the type of oil that can be solubilized, and there is a drawback in that it is difficult to mix silicone, for example.

Further, the liquid crystal structure composition comprising a hydrophilic nonionic surfactant has a drawback in that a large amount of oil can be made transparent, but a large amount of the surfactant to be used is required. Furthermore, the oil film formed after application is easily washed off by water and is suitable for cleansing-type cleansing cosmetics and massage cosmetics, but for cosmetics such as hand creams and hair treatments that require durability. However, there are drawbacks such as being unsuitable and being restricted in application fields.
