The present invention discloses one kind of nanometer baicalin emulsion cosmetics, which is prepared with surfactant, oil, baicalin, essence and distilled water, and through weighing surfactant with or without co-surfactant, calculating HLB value and selecting oil for reaching emulsifying HLB value near that of the surfactant phase, changing the ratio between the surfactant phase and the oil phase regularly to dissolve baicalin, adding distilled water slowly at 20-25 deg.c to form clear and flowing O/W type stable nanometer baicalin emulsion cosmetics. The nanometer baicalin emulsion cosmetics has excellent transdermal permeability, high solubility of baicalin, high effects of whitening, beautifying, eliminating acne and preventing against sun, and excellent extensibility on skin. |
