Abstract:
1. A method of producing a liquid crystal emulsion composition having liquid crystal structure, comprising the steps of: (i) admixing 3 to 8 parts by weight of a hydrophilic surfactant A having an HLB of 10 to 20, which is a polyoxyethylene polyoxypropylene alkyl ether of general formula HO(C (ii) admixing 5 to 14 parts by weight of the resulting admixture obtained from step (i) with 5 to 30 parts by weight of an oil component C; (iii) admixing the resulting admixture obtained from step (ii) with a mixture obtained by mixing 40 to 80 parts by weight of water-soluble polyvalent alcohol D and 8 to 40 parts by weight of water E; and (iv) heating, homogeneously mixing, and then cooling the admixture obtained from step (iii).
