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.
Application
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
Kojic acid may be used as an analytical reference standard for the determination of the analyte in skin whitening cosmetics and bleaching cosmetics using high performance liquid chromatography with UV detection (HPLC-UV).
Biochem/physiol Actions
Tyrosinase inhibitor.
