melting point ： 153-156^`C。

3)        Toxicity test data: LD502500----3500mg/kg。

4)        CAS NO.：501-30-4.

5)        H S code ：2932 9990.

二、Purpose

1)           Daily chemicals material：Because Kojic acid can inhibits caseinase synthesis, then inhibits skin melanin formation, kojic acid and it's derivatives are widely used in high-quality brightening cosmetic, bath cream midtoothpaste. The products containing kojic acid can treat freckle, acne, pigmentation and macula effectively without any toxic and bad results, At present, kojic acid's use level added in cosmetic amounts to 0.2-1.0 percent.   

2)            Food additive：Kojic acid and it's derivatives work as antiseptic, antioxidant, preservative and color stablizer in meat processing, also act as useful materials of food aromatizer - maltol .

3)            Medicine material：Kojic acid and it's derivatives are used as an important material in antibiotic - cethamycin, anodyne, and antiphlogistic production.

4)            Pesticide：Biologic fertilizer with 0.5—1.0% Kojic acid has a clearly effect on increase production both foodstuff and greenstuff.

5)            Others：Kojic acid can be film despecking agent and iron ananysis reagent.
