Arbutin, is a monoglucose of hydroquinone found in the leaves of Rosaceae and in the leaves of azaleas. The natural extraction method has a low extraction yield due to the low content of arbutin in the plant material, and the preparation method is complicated. Therefore, Natural Field uses fermentation to synthesize Alpha-arbutin and uses organic synthesis to synthesize Beta-arbutin. Alpha arbutin powder can inhibit the activity of tyrosinase and is an effective component of biological activity in plants. Therefore, it has become one of the main raw materials in major cosmetics at home and abroad. The preparation method of α-arbutin is obtained by sugar conversion by microbial enzyme, and its stability, effectiveness and safety are better than β-arbutin, and the skin care effect is ten times that of β-arbutin. It has been widely used by many cosmetics brands in the world. The main Function is whitening, anti-inflammatory and anti-irritant. Glutathione (GSH) is an antioxidant in plants, animals, fungi, and some bacteria and archaea. Glutathione is capable of preventing damage to important cellular components caused by reactive oxygen species such as free radicals, peroxides, lipid peroxides, and heavy metals. Glutathione reduced powder is soluble in water, dilute alcohols, liquid ammonia, and dimethylformamide, but not ethanol, ether, and acetone. The solid state of glutathione is relatively stable, and its aqueous solution is easily oxidized to oxidized glutathione (GSSH) in the air. https://www.nfnutra.com/cosmetic-raw-material/
