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.
Function
1) Kojic acid is a kind of specialized inhibitor for melanin. It can prevent the tyrosinase activity through synthesizing with copper ion in the cells after it enters skin cells. Kojic acid and its derivative has better inhibitory effect on tyrosinase than any other skin whitening agents. At present it is assigned into various kinds of cosmetics for curing freckles,spots on the skin of old man,pigmentation and acne.
2) Kojic acid also has antibacterial and antifungal properties.
3) Kojic acid can also eliminate free radical, strengthen cell activity of cell and keep the food fresh.
Application
1) As skin whitening antiaging and lightening agents.
2) As discoloration prevention agents of vegetables and foods.
3) As plant growth-regulating agents.
4) As intermediate in synthesis.
