lotion contains an extract of lightyellow
sophora root, amur corktree
bark and selinum japenious seed,
chlorhexidine acetate, a surfactant,
ethanol and water, wherein the surfactant is selected from lauryl
dimethylamine oxide,
Alcohol Ethoxylate (AEO-9),
Lauric Acid Ethoxylate (LAE-9) and
nonylphenol polyoxyethylene ether (NPE-10); the extract is prepared by performing
reflux extraction on 10-25 percent of lightyellow
sophora root, 35-45 percent of amur corktree

ethanol aqueous solution as an extraction
solvent for 1-3 times, every time for 1-1.5 hours, combining extracting solutions, filtering, recovering a filtrate under reduced pressure in vacuum, and concentrating with
ethanol till the
relative density is 1.08-1.12; and the using amount of the ethanol
aqueous solution is 6-8 times of the total
