Description

  The present invention relates to a skin cleansing agent for wrinkle improvement, which is excellent in wrinkle improving effect, foam foaming power during use, foam creaminess, refreshing feeling after rinsing, and stability over time.

  Conventionally, higher fatty acid salts have been applied to various skin cleansing agents because of their excellent foaming ability and creaminess, and a refreshing feeling after rinsing. (For example, see Patent Documents 1 to 4.)

  In addition, skin cleansing agents containing various water-soluble polymers, nonionic surfactants, and oils have been developed in order to reduce the feeling of stickiness after washing and to give a moist feeling. (For example, see Patent Documents 5 to 7.)

  However, conventional skin cleansing agents did not provide a wrinkle-improving effect even though excellent foaming and moist feeling were obtained.

  In addition, cosmetics with enhanced moisturizing feeling and moisturizing power have been developed by blending an oil agent having a moisturizing power and water retention property into skin care cosmetics and makeup cosmetics. (For example, refer to 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 hydrating oils. , (Adipic acid, 2-ethylhexanoic acid, stearic acid) glyceryl oligoester, (12-hydroxystearic acid, stearic acid, rosin acid) dipentaerythritol ester, lanolin fatty acid cholesteryl, isostearic acid cholesteryl, 12-hydroxystearic acid Cholesteryl derivatives such as cholesteryl, ricesteryl ricinoleate, macadamia nut oil fatty acid cholesteryl, lanolin fatty acid phytosteryl, phytosteryl isostearate, phytosteryl 12-hydroxystearate, ricin Phytosterol derivatives such as phytosteryl oxalate, macadamia nut oil fatty acid phytosteryl, lanolin, adsorption purified lanolin, liquid lanolin, lanolin alcohol, hydrogenated lanolin alcohol, lanolin derivatives such as lanolin fatty acid, dipentaerythritol such as dipentaerythritol fatty acid ester Derivatives and the like are used.

  However, even if these moisturizing power and water-holding oil are blended in the skin cleanser, the moisturizing power and moisturizing feeling can be improved, but the wrinkle improving effect has not been obtained. Further, even though it can be added, many foams which are important as a function of the cleaning agent are inhibited.

Japanese Patent No. 4357431 Japanese Patent No. 4381270 Japanese Patent No. 3547923 JP 2002-154946 A Japanese Patent No. 4991177 JP 2001-213761 A Japanese Patent No. 2630529 JP 2007-161610 A JP 2004-269396 A JP 2003-226609 A JP 2003-286126 A JP 2004-143063 A
