Kojic acid Chemical Properties,Uses,Production

Chemical Properties

tan powder

Uses

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.

Definition

ChEBI: 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.

General Description

Kojic acid, a tyrosinase inhibitor, is produced by several fungi species, including Aspergillus oryzae. It exhibits skin-lightening property, due to its ability to chelate the copper-containing enzyme tyrosinase in the formation of melanin. Kojic acid is also commonly used as a whitening agent in regular cosmetics, bleaching cosmetics, etc. It is found to be a therapeutic agent and helps in preventing pigmentation.

Purification Methods

Crystallise the acid from MeOH (charcoal) by adding Et2O. It sublimes at 150-200o/0.1torr. [Beilstein 18 II 57, 18 III/IV 1145, 18/2 V 516.]
