Arbutin soluble in water, methanol, ethanol and propylene glycol, glycerol aqueous solution, insoluble in ether, chloroform, petroleum ether. Arbutin with minerals from the plants and animals, by chemical synthesis and artificial composite of fatty, lipid of components, such as: fat, ester oil, also known as chemical synthetic oil, fat, rich fat, ester wax, fatty acid, lipid Alcohols, sterols, polyhydric alcohol fatty acid single or double lipid, sterol ester resin, paraffin wax, chemical structure of the oil, polydimethylsiloxane chain ring, and the oil of the pigment. Vitamins, anti-corrosion components, auto-oxidation resistant components, etc., irrelevant interference.Arbutin in acidic conditions, unstable and susceptible to hydrolysis. Arbutin aqueous solution with low iron or high iron generated shallow black water-soluble complex; can and alkaline lead acetate precipitation reaction. Therefore, the required formula in the conductivity of the water added should be less than 10, the formula has not added arbutin guar gum, or affect its stability
