Abstract

A liquid cosmetics has a good sensation of use and stability even in the presence of a water soluble L-ascorbic acid derivative. The liquid cosmetics is characterized in comprising: (a) a sterol derivative having an average addition mole number of ethylene oxide of 2~30 moles; (b) a softener; (c) a water soluble L-ascorbic acid derivative, as necessary ingredients. Furthermore, the mass ratio of the component (a) to the component (b) is 20:1~1:20.

Description

technical field [0001] The present invention relates to a liquid cosmetic obtained by stably dispersing a lubricant in the presence of a water-soluble ascorbic acid derivative. More specifically, it relates to a liquid cosmetic which has an excellent moisturizing effect, does not feel sticky when used, has good usability, and maintains its appearance for a long time liquid cosmetics. Background technique [0002] In the past, water-soluble ascorbic acid derivatives were widely used to formulate cosmetics because of their good whitening effect. However, if these cosmetics contain a large amount of water-soluble vitamin C derivatives, they produce a unique sticky feeling and a feeling of forming a mucous membrane, so that the feeling after use is not good. In order to obtain a good use effect, the prior art adopts a method of mixing high molecular weight substances such as water-soluble polymer compounds or waxes and a method of mixing lubricants such as oil to suppress the s...
