Abstract:
1. A method for producing a pearly luster composition comprising pearly luster particles (A) comprising a fatty acid glycol ester (a1) represented by the formula (I): wherein each of R and a fatty acid glycol ester (a2) represented by the formula (II): wherein each of R wherein said fatty acid glycol ester (a2) has a melting point higher than the melting point of the fatty acid glycol ester (a1), and a surfactant (B), wherein the method comprises 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, such that said mixing is before precipitation of crystals of said fatty acid glycol ester (a2); and (iii) cooling the emulsified mixture obtained in the step (ii), to precipitate the pearly luster particles (A).
