Description

The present invention relates to a wrinkle-improving skin cleanser having excellent wrinkle-improving effect, foam-foaming power during use, foam creaminess, refreshing feeling after rinsing, and aging stability.

Conventionally, higher fatty acid salts have been applied to various skin cleansers because of their excellent foaming power and creaminess, and the refreshing feeling after rinsing. (See, for example, Patent Documents 1 to 4.)

Further, skin cleansers containing various water-soluble polymers, nonionic surfactants, and oils have been developed in order to give a moist feeling with less tension after washing. (See, for example, Patent Documents 5 to 7.)

However, conventional skin cleansers have not been effective in improving wrinkles, even though they have excellent foaming and moisturizing sensations.

In addition, cosmetics with enhanced moisturizing sensation and moisturizing power have been developed by blending skin care cosmetics and make-up cosmetics with oils having moisturizing power and water-holding power. (See, for example, Patent Documents 8 to 12.)

Among these cosmetics, N-lauroyl-L-glutamate di (cholesteryl behenyl octyldodecyl) and N-lauroyl-L-glutamate di (phytosteryl behenyl octyldodecyl) are used as water-holding oils. , (Adipic acid, 2-ethylhexanoic acid, stearic acid) glyceryl oligoester, (12-hydroxystearic acid, stearic acid, logonic acid) dipentaerythritol ester, lanolin fatty acid cholesteryl, cholesteryl isostearate, 12-hydroxystearic acid Cholesteryl, cholesteryl lysinolate, cholesterol derivatives such as macademia nut oil fatty acid cholesteryl, phytosterol derivatives such as phytosteryl lanolin fatty acid, phytosteryl isostearate, phytosteryl 12-hydroxystearate, phytosteryl lysinolate, phytosteryl macadamia nut oil fatty acid, lanolin, liquid Lanolin derivatives such as lanolin, lanolin alcohol, hydrogenated lanolin alcohol, and lanolin fatty acids, and dipentaerytrit derivatives such as dipentaerytrit fatty acid esters are used.

However, although it is possible to improve the moisturizing power and the moisturizing feeling only by adding these moisturizing power and water-holding oil agents to the skin cleansing agent, the wrinkle improving effect has not been obtained. Although it was possible to further blend, in many cases, foaming, which is important as a function of the cleaning agent, was hindered.
