Kojic acid is known as 5- hydroxyl -2-hydroxymethyl -1 and 4- piranone. It is a weak acidic organic compound made by fermentation of microorganisms. Fine Kojic acid is a white or yellowish needle like crystal; easily soluble in water, alcohol and aceton,slightly soluble in ether, ethyl acetat, chlorofor and pyridin, insoluble in benzene,Melting point is 153~156ºC.
Application:

(1) it is applied in the field of cosmetics. In the human skin, tyrosine is synthesized by the complex oxidation and polymerization of oxygen free radicals under the catalysis of tyrosinase, and finally the melanin is synthesized. Kojic acid can inhibit the synthesis of tyrosinase, so it can strongly inhibit the formation of skin melanin, and it is safe and non-toxic, and will not produce leukoplakia, so kojic has been added into the make-up water, mask, emulsion, skin cream, and can effectively treat freckles, old age spots, pigmentation, acne and other whitening cosmetics.20ug/mlA variety of tyrosinase can be inhibited by the concentration of kojic acid(Or polyphenol oxidasePPO)70 to 80% of the vitality is recommended in cosmetics, adding 0.2 to 1%. (2)Kojic acid is the raw material for producing maltol and ethyl maltol. (3)In the field of medicine, as kojic acid has no mutagenic effect on eukaryotic cells, it can also eliminate the internal free radicals, enhance the power of the white cell, and be beneficial to the health of the human body. Therefore, koji has already been used as the raw material of cephalosporins, and the finished product is used to treat the diseases such as headache and toothache, and the analgesic and anti-inflammatory effects are ten Divide the ideal. (4)In agricultural field, kojic acid can be used to produce biological pesticides. The bio micro fertilizer (deep red liquid), made of 0.5 to 1% kojic acids, is applied to the grain and vegetable, whether it is a low concentration as a foliar fertilizer or a growth increasing agent for root application. (5)In other fields, kojic acid can also be used as iron analysis reagent, film speckle inhibitor, etc.
