Kojic Acid & Kojic Acid dipalmitate

1. Kojic Acid

Chemical name:5-hydroxyl-2-hydroxymethyl-1, 4-pyrone.

It is a white needle-like crystals. It easily dissolves in water, alcohol & aceton, and slightly dissolves in ethyl acetate, chloroform, etherand pyridine. Kojic acid does not dissolve in benzene.

Molecular weight: 142.1

Cas no: 501-30-4

Melting point: 153-156C

Molecular formula: C6H6O4

Toxicity test data: LD502500-350Omg/kg.


(1) Daily chemicals material:

Because Kojic acid can inhibits caseinase activity, then inhibits skin melanin formation, kojic acid and it's derivatives widely used in high-quality skin lightening cosmetics, bath preparation and mouth or teeth care products. Cosmetics 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 cosmetics is to 0.2-1.0 percent.

(2) Medicine material:

(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 ethylmaltol.

(4) Preservative and color stablizer of cut-flower:

Kojic acid and it's derivatives are added to cut-flower to keep flower colorful and fresh.

(5) Film despecking agent and iron ananysis reagent.

(6) Non-toxic to person and livestock, pollution-free pesticide ininsecticide production
