Kojic Acid / Kojic Dipalmitate
Kojic acid is used for macula-removing and whitening.In the human skin, tyrosine is oxidized and polymerized with oxygen-derived free radicals under the catalytic action of tyrosinase and then synthesized to melanin. Kojic acid can inhibit tyrosinase synthesis, so it can largely inhibit the skin melanin formation; furthermore, kojic acid is safe and nontoxic and won’t cause white spot syndrome. Therefore, it has been widely added into the lotion, face mask, liquid cream and skin cream. Whitening cosmetics containing kojic acid are able to treat effectively the freckle, senile plaque, pigmentation and acne, etc. Kojic acid in concentration of 20ug/ml is able to inhibit 70~80%of the activity of many kinds of tyrosinases (or polyphenoloxidase PPO) .Kojic acid is widely used in high-quality skin lightening cosmetics, bath preparation and mouth or teeth care products. Cosmetics containing kojic acid can treat freckle,acne, pigmentation and macula effectively without any toxic and side effects;It is also used as an important material in antibiotic -cephamycin, anodyne, and antiphlogistic production; It is also used as antiseptic,antioxidant, preservative and color stablizer in meat processing, also act as useful materials of food aromatizer – maltol and ethylmaltol.
