Kojic acid is white or off-white needle-like crystals,
easily dissolved in water, alcohol and acetone; slightly
dissolved in ether, ethyl acetate, chloroform and
pyridine; and undissolved in benzene. The molecular
formula is C6H6O4; molecular weight is **2.1; melting
point is **3~**6℃. CAS: **1~*0~4. Usage: (1) Application in cosmetic field: It is used for macula-removing and whitening.In the human skin, tyrosine is oxidized and polymerized with oxygen-derived free radicals under the catalytic action of tyrosinase and then synthesized to melanin. Kojic acid can inhibit tyrosinase synthesis, so it can greatly inhibit the skin melanin formation; furthermore, kojic acid is safe and nontoxic and won’t cause white spot syndrome. Therefore, it has been widely added in the lotion, face mask, liquid cream and skin cream. Whitening cosmetics containing kojic acid are able to treat effectively the freckle, senile plaque, pigmentation and acne, etc. Kojic acid in concentration of *0ug/ml is able to inhibit *0~*0%of the activity of many kinds of tyrosinases (or polyphenoloxidase PPO) . 0.2~1.0% of kojic acid is recommended to be added in the cosmetics.

The finished products have ideal effect in easing pain, relieving inflammation and curing many diseases (like headache and toothache, etc.). (4) In agriculture field: Kojic acid is used in producing biological pesticides. 0.**1.0% of kojic acid can be added in microelement fertilizer (crimson liquid). This kind of crop production promoter has significant effect on increasing production of grains and vegetables, no matter it is used as low-concentration foliage fertilizer for spraying or yield-increasing agent for root applying.
