Description and Application:

Kojic acid is a highly effective whitening agent that effectively inhibits the activity of tyrosinase and blocks or delays the formation of melanin. In the non-cellular assay in vitro, can effectively inhibit the activity of tyrosinase, non-competitive inhibition way. It binds to copper ions, causing copper ions to lose their activation of tyrosinase.

Kojic acid is found in people's production activities. It is well known that the skin of workers who make soy sauce, bean paste, and wine is always white. Inspired by this, people extracted this ingredient from filamentous fungi such as Penicillium and Aspergillus. Kojic acid is a safe substance.

Kojic acid is suitable for use in high-end cosmetics such as whitening skin care and freckle. It is widely used as a food antioxidant, antibacterial agent and anti-tarnishing agent. Adding kojic acid to foods can effectively prevent rancidity of oils and inhibit the conversion of sodium nitrite into carcinogenic nitrosamines. Kojic acid has a good food preservation and antiseptic effect.
