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.
