Patent ID: 8030266

Claim:
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): R 1 COO-(A 1 O) x —COR 2 (I) wherein each of R 1 and R 2 is independently an alkyl group having 13 to 21 carbon atoms, A 1 is a —C 2 H 4 — group or a —C 3 H 6 — group, and x is the number of from 1 to 10, and a fatty acid glycol ester (a2) represented by the formula (II): R 3 COO-(A 2 O) y —COR 4 (II) wherein each of R 3 and R 4 is independently an alkyl group having 15 to 21 carbon atoms, A 2 is a —C 2 H 4 — group or a —C 3 H 6 — group, and y is the number of from 1 to 10, 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).
