Kojic acid CAS# 501-30-4
Kojic acid (CAS# 501-30-4) is a natural compound produced by microbial fermentation and is commonly found in the metabolites of Aspergillus and penicillium fungi. The chemical name was 5-hydroxy-2-hydroxymethyl-4h-pyrano-4-one. The molecular form was ₆. H₆O₄, and the molecular weight was 142.11. Kojic acid has a certain acidity and is relatively stable in acidic and neutral environments. It can chelate with metal ions and affect the activity of some enzymes, especially related to tyrosinase, which can reduce the production of melanin by inhibiting the activity of the enzyme, and is often used in the field of whitening skin care. In the food industry, due to its antioxidant properties, it can prevent food Browning and extend the shelf life.

Product Usage
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.
