Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning agent having an improved mild action on the skin, excellent foaming power, and a stable pearl luster. Material composition. [0002] Cleaning of the skin is one of the important factors to keep healthy and beautiful skin. Skin has a different skin quality depending on age, gender, constitution, and the like. Therefore, it is important to properly select a cleaning agent that matches the skin type and use it in an appropriate manner (Yuki Fujisawa, Kayoko Matsunaga: Fragrance Journal, 199)
6, 7, 9-16). [0003] Conventionally, as a surfactant for detergents,
Anionic surfactants such as alkyl sulfates, polyoxyethylene alkyl ether sulfates, and α-olefin sulfonates are widely used. However, these anionic surfactants have the drawback of inducing skin irritation to varying degrees. To remedy this drawback, mild bases for the skin include monoalkyl phosphates, acyl glutamates, acyl methyl taurates, cocoyl isethionates, N-lauroyl-β-alanine, alkyl saccharides (Toshiyuki Suzuki: Functional Cosmetics II, 99-111, 1996, CMC). Further, Japanese Patent No. 2571121 proposes a low-irritant detergent composition containing a sulfosuccinic acid-based surfactant. [0005] On the other hand, for the purpose of imparting a high-grade feeling by pearl luster and adjusting the consistency of the preparation, blending of natural fish phosphorus foil, blending of pearl pigments such as bismuth oxychloride, mica and titanium, etc. It has been known. However, these pearling agents have high raw material prices, poor light resistance,
It has various drawbacks, such as a problem with skin safety and settling during storage. Furthermore, ethylene glycol distearate is widely used as a pearl brightener, but has the disadvantage that it melts and dissolves at a temperature of about 40 to 50 ° C., does not exhibit the original pearl luster again, and significantly impairs the appearance. I have. [0006] The present inventors have sought to remedy such drawbacks of the conventional products by using specific ethylene glycol difatty acid esters, isethionate-type anionic surfactants, N-acylglutamate and N-acylaspartate. Was found to be a facial cleanser composition having a mild action on the skin, excellent foaming power, and good pearl luster. 6-157292).
