English description（英文原文，共 1131 字符）
Product Name:Kojic acid
English Name:Kojic acid
CAS No.:501-30-4
Aliases:Kojic acid, 5-Hydroxy-2-(hydroxymethyl)-4H-pyran-4-one
Molecular Formula:C6H6O4
Physical Properties:Off-white crystalline powder; soluble in water, ethanol and acetone, slightly soluble in ether; melting point 152-156°C; unstable to light, heat and metal ions; exhibits antioxidant activity and UV absorption capacity.
Uses:Kojic acid is used as a skin-lightening agent in cosmetics, inhibiting tyrosinase activity and reducing melanin formation for the formulation of anti-freckle and whitening products. In the food industry, it serves as a preservative, freshness-retaining agent and antioxidant, preventing enzymatic browning of fruits and vegetables, and also as a raw material for producing maltol and ethyl maltol. In the pharmaceutical field, it is used as an intermediate for cephalosporin antibiotics. In agriculture, it is applied in the production of biopesticides and plant growth promoters.
Technical Specifications:
Assay ≥ 99.0%
Melting point 152-156°C
Loss on drying ≤ 0.5%
Residue on ignition ≤ 0.1%
Heavy metals (as Pb) ≤ 3 ppm
