[0081] The present invention also provides a preparation method of the whitening liquid crystal composition described in the above technical solution, comprising the following steps:
[0082] A. Dissolving liquid crystal emulsifier and non-water-soluble whitening active ingredient in liquid lipid to obtain oil phase;
[0083] B. Dissolving co-emulsifier and emulsification thickener in water to obtain water phase;
[0084] C. Dissolving the water-soluble whitening active ingredient in water to obtain an aqueous solution of the whitening active ingredient;
[0085] D. Mix and emulsify the oil phase obtained in step A with the water phase obtained in step B, and micronize it to obtain a micron-scale dispersion;
[0086] E. Mix and emulsify the aqueous solution of whitening active ingredients obtained in step C with the micron-sized dispersion obtained in step D, and perform nano-processing to obtain a whitening liquid crystal composition;
[0087] There is no sequence limitatio...
