Product Detail

Kojic acid

Kojic acid is a melanin-specific inhibitor that binds to copper ions in cells after entering the skin cells, alters the steric structure of tyrosinase, and prevents the activation of tyrosinase, thereby inhibiting the formation of melanin. Kojic acid active agents have better tyrosinase inhibition than other active agents. It has been formulated into various cosmetics and is a widely used cosmetic active agent. Kojic acid has an antioxidant effect in foods, which inhibits the conversion of sodium nitrite into nitrosamines in foods without affecting the taste, aroma and texture of the food. As a production promoter, it has obvious effects on grain and vegetables.

ECHEMI Editorial Reference

Kojic acid is a natural substance produced by Aspergillus oryzae, also used as an anti-oxidant and radio-protective agent[1].
Solid
Kojic acid is a pyranone that is 4H-pyran substituted by a hydroxy group at position 5, a hydroxymethyl group at position 2 and an oxo group at position 4. It has been isolated from the fungus Aspergillus oryzae. It has a role as a NF-kappaB inhibitor, an Aspergillus metabolite, a skin lightening agent, an EC 1.10.3.1 (catechol oxidase) inhibitor, an EC 1.10.3.2 (laccase) inhibitor, an EC 1.13.11.24 (quercetin 2,3-dioxygenase) inhibitor, an EC 1.14.18.1 (tyrosinase) inhibitor and an EC 1.4.3.3 (D-amino-acid oxidase) inhibitor. It is an enol, a primary alcohol and a member of 4-pyranones. It derives from a hydride of a 4H-pyran.
