| Description: | kojic acid CAS No.501-30-4 Skin Care whitening agent Chemical name: kojic acid Alisa: kojic;2-HYDROXYMETHYL-5-HYDROXY-1,4-PYRONE ;5-hydroxy-2-hydroxymethyl-1,4-pyrone CAS NO. : 501-30-4 EINECS NO.: 207-922-4 Molecular Formula: C6H6O4 Molecular Weight: 142.11 Test Standard： Appearance:White or off-white crystal Purity:≥ 99.0% Melting Point: 152-156℃ Loss on drying:≤ 0.5% Residue on ignition:≤ 0.1% Heavy Metal:≤ 3ppm Iron:≤ 10ppm Arsenic:≤ 1ppm Chloride:≤ 100ppm 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) . | |
