Product Description

Product Description of Kojic Acid#501-30-4

Kojic acid (CAS 501-30-4) is a tyrosinase inhibitor produced by Aspergillus oryzae and other fungi. It works by chelating copper in tyrosinase, inhibiting melanin production and offering skin whitening effects. It is widely used in cosmetics and whitening creams for skin brightening and improving pigmentation problems.

Product Application of Kojic Acid#501-30-4

Kojic acid (CAS#501-30-4) acts as a skin whitener with antioxidant effects. It serves as a tyrosinase inhibitor and works milder than licorice extract. Blended with allantoin and other ingredients in sunscreen, it helps reduce UV-caused erythema and accelerates skin wound recovery. It may occasionally lead to skin sensitivity and irritation.
