【 Characteristics and Applications 】 It is a skin decolorizing component confirmed in the 1950s as originating from green plants and possessing significant inhibitory activity against tyrosinase. Arbutin has a high decolorization effect on freckles, butterfly spots (also known as melasma and pregnancy spots), as well as pigmentation and skin pigmentation, and is safe and reliable. It can be combined with fatty and lipophilic components derived from animal, plant, and mineral sources, chemically synthesized and artificially compounded, such as fatty acids, esters, also known as chemically synthesized oils, mono - or di steroidal fatty acids, esters, fatty acids, polyols, sterol polyols, alkane chemical structures, cyclic polydimethylsiloxane, and oil-based pigments. Vitamins, anti-corrosion components, anti auto oxidation components, etc., do not interfere with each other. Under acidic conditions, it is unstable and easily hydrolyzed, and the aqueous solution of arbutin or high-speed iron forms a water-soluble light black complex; Can undergo precipitation reaction with basic lead acetate. Adding an appropriate amount (1-3%) of vitamin E to the formula can enhance stability and should not be combined with guar gum. Adding an appropriate amount of sodium bisulfite can prevent the paste from changing color. Suitable for high-end cosmetics such as whitening, skincare, and spot removal.
