Uses:
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, toothpaste. 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%.
2) Medicine material:
Kojic acid and it's derivatives are used as an important material in antibiotic - cethamycin, anodyne, and antiphlogistic production.
3) 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 and ethyimaltol.
4) Preservative and color stablizer of cut-flower:
Kojic acid and it's derivatives are added to cub-flower to keep the flower colorful and fresh.
5) Film despeckling agent and iron analysis reagent.
6) Non-toxic to person and livestock, pollution-free pesticide in insecticide production.
The third monomer of acrylic fiber: acrylic fiber which adopts ITACONIC ACID as the third monomer is easy to dye.
