Abstract: A pearly luster composition containing a fatty acid glycol ester and water, and further containing any one selected from the group consisting of (1) a polyoxyalkylene nonionic surfactant and a fatty acid contained in an amount of from 0.3 to 3% by weight of the pearly luster composition, (2) a polyoxyalkylene nonionic surfactant and an aliphatic alcohol contained in an amount of from 0.3 to 3% by weight of the pearly luster composition, (3) a fatty acid monoglyceride contained in an amount of from 0.3 to 3% by weight of the pearly luster composition, and (4) an aliphatic ether contained in an amount of from 0.3 to 3% by weight of the pearly luster composition, as a crystallization additive. The pearly luster composition of the present invention is suitably used for shampoos, conditioners, body shampoos, liquid detergents, and the like.

Abstract: A method for producing a pearly luster composition containing pearly luster particles (A) containing a fatty acid glycol ester (a1) and a fatty acid glycol ester (a2) having a melting point higher than the melting point of the fatty acid glycol ester (a1), and a surfactant (B), wherein the method includes the steps of (i) solubilizing the fatty acid glycol ester (a2) in the presence of the surfactant (B); (ii) mixing the solubilized solution obtained in the step (i) with a molten fatty acid glycol ester (a1), to emulsify the mixture; and (iii) cooling the emulsified mixture obtained in the step (ii), to precipitate the pearly luster particles (A); a pearly luster composition obtained by the method; and a shampoo containing the pearly luster composition. The pearly luster composition obtained by the present invention is suitably used for shampoos, conditioners, body shampoos, liquid detergents, and the like.

Abstract: A method for producing a pearly luster composition containing a fatty acid glycol ester, a surfactant, and water, and further containing as a crystallization additive any one selected from the group consisting of (1) a fatty acid, (2) an aliphatic alcohol, (3) a fatty acid monoglyceride, and (4) an aliphatic ether, the method including the step of cooling a molten mixture solution containing the fatty acid glycol ester, the surfactant, water, and the crystallization additive, wherein a representative heat-removal rate per unit mass during crystallization in the cooling step is from 9 to 36 [W/kg]. The pearly luster composition obtained by the method of the present invention can be suitably used for shampoos, conditioners, body shampoos, liquid detergents, and the like.
