Abstract: The present invention aims to provide a production method of a composition containing (A) glycerol and (B) glycine, which includes using glycerol substantially free of dihydroxyacetone or having a dihydroxyacetone content of not more than 150 ppm. According to the present invention, a composition, particularly a cosmetic composition, having a moist feeling but free of stickiness and showing suppressed coloration can be provided.

Abstract: Provided is a cleansing composition of acyl amino acid, showing good foamability and good lather retention effect, which is rinsed off quickly and affords superior skin texture after drying. A cleansing composition containing the following components (A), (B) and (C), wherein a weight ratio of (A)/(B) is 0.2-5 and a weight ratio of ((A)+(B))/(C) is 2.5-10.0: (A) N-lauroylglycine or a salt thereof (B) N-myristoylglycine or a salt thereof (C) N-acyl acidic amino acid having an acyl group having 8-24 carbon atoms, or a salt thereof.

Abstract: The present invention provides a transparent solid detergent containing (A) N-acyl acidic amino acid salt, (B) acylglycine salt and (C) polyvalent alcohol, at a proportion of (A) 4.5-5000 parts by weight and (C) 2.5-2400 parts by weight, per 1 part by weight of (B), which suppresses coloration by heating during production, is superior in preservation stability at low temperature and high temperature, is low irritant, and shows good sense of use.

Abstract: Provided is a composition containing a sterol ester, which is an oil poorly soluble in water, and superior in transparency, stability, foaming property, rinsability, skin feel (during rinsing and/or after use), and emollience. A composition containing (A) a sterol ester, (B) one or more anionic surfactants selected from (B1) N-acylamino acid having a C8-22 acyl group or a salt thereof, (B2) polyoxyethylene alkyl ether sulfate or a salt thereof, (C) a betaine-type amphoteric surfactant, (D) glyceryl mono-C8-14 fatty acid ester, (E) C5-6 hydroxyalcohol, and (F) water, and having pH 4-8.
