Project Description

Chemical NameKojic acid
CAS No.501-30-4
Molecular Formula:C6H6O4
Molecular Weight:142.11
EINECS:207-922-4
Applications: 

Kojic acid has uses in areas such as cosmetics, food additives, pharmaceuticals etc. Because kojic acid and its derivatives can safely supress the growth of human skin melanin, it is used in skin whitening cosmetics, bath lotions, toothpaste etc. Kojic acid is also anibacterial and therefore prevents oxidation and preserves color, leading to its use in food preservatives, oil antioxidants, preventing fruit and vegetables from becoming stale, and preserving the color of meat and aquatic products. Kojic acid may also be used in chemical intermediate products, agriculural plant protection, chemical reagents and in antibiotics.
