Patent ID: 7696254

Claim:
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 2 H 4 O) n —(C 3 H 6 O) m R, where n is an integer from 15 to 50, m is an integer from 4 to 16, and R is an alkyl group selected from those having 12 to 24 carbon atoms, with 2 to 6 parts by weight of a lipophilic surfactant B; (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).
