ず、皮膚の健康維持上望ましくなかつた。BACKGROUND ART Human skin is covered with an acid mantle, and in a healthy state, exhibits a weak acidity (pH 4.5 to 6.5). Therefore, it is desirable for maintaining the health of the skin that the cosmetic applied to the skin is also weakly acidic. So, conventionally,
Water-soluble as a gelling agent, in a gel cosmetic using a carboxyvinyl polymer, in order to neutralize the carboxyvinyl polymer and make the cosmetic a desired weak acidity,
In general, amines such as triethanolamine and diethanolamine are used. However, it has been reported that these amines exert undesired effects such as irritation on the skin. Therefore, attempts have been made to use basic amino acids, alkali metal hydroxides, etc. as neutralizing agents. However, when these neutralizing agents are used, the cosmetic does not gel sufficiently under weak acidity and is suitable. It must be used weakly basic to form gels of various viscosities, which is not desirable for maintaining skin health.
本発明者は、以上の問題点を克服すべく種々検討を重ね

完成するに至つた。The present inventor, while conducting various studies to overcome the above problems, surprisingly, weakly acidic by neutralizing the water-soluble carboxyvinyl polymer with arginine and sodium hydroxide or potassium hydroxide in combination. It was found that a gel-like cosmetic giving an appropriate viscosity can be obtained by the above, and the present invention has been completed.

のゲル状化粧料が得られる。DISCLOSURE OF THE INVENTION That is, the present invention provides a weakly acidic gel cosmetic containing a water-soluble carboxyvinyl polymer, arginine, and sodium hydroxide or potassium hydroxide. According to the present invention, a weak acidity (pH 4.0 to 6.8) that is desirable for maintaining health is maintained without damaging the acid film of the skin.
The gel-like cosmetic of is obtained.

To 5.0% by weight, preferably 0.1 to 2.0% by weight, and sodium or potassium hydroxide is 0.01 to 5.0% by weight, preferably 0.05 to 2.0% by weight relative to the total amount of the cosmetic.
It is compounded in the range of weight%. The amount of arginine and either sodium or potassium hydroxide is 0.01
If it is less than wt%, a good gel will not be formed in weak acidity, and if the total amount of both is more than 8.0 wt%, the cosmetic will become basic, resulting in the desired weakly acidic gel cosmetic. I can't get paid.
