However, when PEG is used, it is easy to flow down from the skin, and the application of a sense of urgency is insufficient. When a high-grade alcohol is used, the agent is thickened with time and the storage stability of the preparation is good I knew it was not.

An object of the present invention is to provide a cosmetic for emulsification which is excellent in storage stability while imparting a sense of firmness and richness.

That is,

According to the present invention, it is possible to provide an emulsified cosmetic composition having excellent storage stability while imparting a sense of firmness and richness. The " elasticity feeling " refers to a feeling that the skin becomes taut. The above-mentioned " rich sense " refers to a feeling that the agent having a high concentration is applied at the time of application.

The emulsifying cosmetic composition of the present invention is a cosmetic emulsifying composition containing the components A to E.

The inventors of the present invention have found that a cosmetic composition for imparting elasticity can be produced by using the octenyl succinate-treated starch aluminum as component A in a hydrated state. However, it has been found that when the emulsified cosmetic composition containing the component A is stored at a low temperature (5 DEG C or less), the elasticity of the emulsified cosmetic composition becomes high and becomes jelly and the stability is lowered. This phenomenon is presumed to be caused by aging of starch. Therefore, the inventors of the present invention have found that by applying glyceryl monobenzoate of component B, xanthan gum of component C and carboxyvinyl polymer (or alkyl-modified carboxyvinyl polymer) of component D among the various various components that can be used in cosmetics field, , It has been found that the low-temperature stability of the cosmetic composition can be improved and a rich feeling can be imparted to the skin.

In the case where the amount of the component A did not reach the specified range and the C / A value exceeded the prescribed range (Comparative Example 4), the feeling of elasticity was inferior. In Comparative Example 5 in which the amount of the component A exceeded the specified range and the C / A value did not reach the specified range, the low-temperature stability was inferior, and coating residue occurred at the time of application to the skin. (Comparative Example 6) in which the amount of the component B did not reach the specified range, the high temperature stability and rich feeling were inferior, and the product was separated into two layers. In the case where the amount of the component B exceeded the specified range (Comparative Example 7), the high temperature stability was inferior, and the product was reduced in viscosity. In the case where the C / A value did not reach the specified range (Comparative Example 8), the low-temperature stability was inferior. In the case where the C / A value exceeded the prescribed range (Comparative Example 9), the rich feeling was inferior, and slipperiness was felt upon application to the skin.

On the other hand, the emulsifying cosmetic compositions of the present invention containing the components A to E and containing the components A, B, and D in the specified ranges and having both the C / A value and the D / 14) exhibited excellent storage stability at a low temperature and a high temperature, and were excellent in a sense of firmness and richness.
