(1) In cosmetics: Tyrosine undergoes complex oxidation and polymerization with oxygen free radicals under the catalytic action of tyrosinase, and finally synthesizes melanin. Kojic acid can inhibit the synthesis of tyrosinase, which is safe and non-toxic. Therefore, kojic acid has been mixed into lotion, facial mask, lotion and skin cream. A concentration of 20ug/ml of Kojic acid can inhibit 70-80% of the activity of various tyrosinases (or polyphenol oxidase PPO), and it is recommended to add 0.2-1.0% in cosmetics.
(2) Kojic acid is a raw material for the production of maltol and ethyl maltol.
(3) In Pharmacy, due to its non mutagenic effect on eukaryotic cells and ability to eliminate free radicals in the human body, Kojic acid has been used as a raw material for cephalosporin antibiotics.
(4) In agriculture, Kojic acid can be used to produce biopesticides. Biological micro fertilizer (dark red liquid) made by adding 0.5-1.0% kojic acid, whether sprayed as foliar fertilizer at low concentrations or used as a growth and yield increasing agent for root application, is widely used as a crop production promoter.
