Kojic acid Uses

1.  A naturally occurring chelation agent.
2.  hydroxystearate nonionic solubilizer

3.  Converted to maltol and ethyl maltol, flavor-enhancing additives. Food additive to inhibit tyrosinase.

4.   kojic acid is a skin-lightening agent that acts through anti-oxidant activity. Kojic acid is a tyrosinase inhibitor, although it is not as effective as licorice extract. When combined with allantoin and other proper ingredients in sunscreen preparations, the mixture can inhibit uV-caused erythema and accelerate wound healing. It is also found to be skin sensitizing and can be irritating.
