Abstract:
1. A method of producing a liquid crystal emulsion composition, comprising the steps of: (i) admixing 3 to 6 parts by weight of a hydrophilic surfactant A having an HLB of 10 to 20 which is selected from polyoxyethylene polyoxypropylene alkyl ethers of general formula HO(C (ii) admixing the resulting admixture obtained in step (i) with 2 to 5 parts by weight of a lipophilic surfactant C; (iii) admixing 8 to 17 parts by weight of the resulting mixture obtained from step (ii) with 5 to 26 parts of an oil component D; (iv) admixing the resulting admixture obtained from step (iii) with a mixture obtained by mixing 40 to 80 parts by weight of a water-soluble polyvalent alcohol E and 8 to 40 parts by weight of water F; (v) heating and homogeneously mixing the resulting admixture obtained from step (iv); and (vi) cooling the resulting product obtained in step (v).
