Applications:It is applied in the field of cosmetics. In the human skin, tyrosine is synthesized by the complex oxidation polymerization of oxygen free radicals under the catalysis of tyrosinase, finally the melanin is synthesized. Kojic Acid can inhibit the synthesis of tyrosinase, so it can strongly inhibit the formation of skin melanin, it is safe non-toxic, will not produce leukoplakia, so Kojic has been added into the make-up water, mask, emulsion, skin cream, can effectively treat freckles, old age spots, pigmentation, acne other whitening cosmetics.20ug/ml.A variety of tyrosinase can be inhibited by the concentration of Kojic Acid 70 to 80% of the vitality is recommended in cosmetics, adding 0.2 to 1%.Kojic Acid is the raw material fproducing maltol ethyl maltol.In pharmaceutical,k\Kojic Acid has no mutagenic effect on eukaryotic cells, it can also eliminate the internal free radicals, enhance the power of the white cell, be beneficial to the health of the human body. Therefore, Kojic Acidhas already been used as the raw material of cephalosporins, the finished product is used to treat the diseases such as headache toothache, the analgesic anti-inflammatory effects are ten Divide the ideal.In agricultural field,it 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 vegetable, whether it is a low concentration as a foliar fertilizer a growth increasing agent froot application.Kojic Acid can also be used as iron analysis reagent, film speckle inhibitor, ect.
