Általános leírás
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.
Alkalmazás
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).
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Tyrosinase inhibitors have become increasingly critical agents in cosmetic, agricultural, and medicinal products. Although a large number of tyrosinase inhibitors have been reported, almost all the inhibitors were unfortunately evaluated by using commercial available mushroom tyrosinase. Here, we examined the
