Kojic Acid Dipalmitate CAS 79725-98-7

As a fat-soluble whitening agent, kojic acid dipalmitate is easier to formulate and can be more effectively absorbed by skin, while bringing good moisturizing effect to our skin.



Kojic acid dipalmitate is an improved derivative of kojic acid, which overcomes the instability of kojic acid to light, heat and metal ions, and maintains the effect of inhibiting tyrosinase activity and blocking melanin formation of the skin.

1. Skin whitening;
2. Helps absorption of cosmetics to the skin;
3. Has antibacterial, antifungal, and antioxidant attributes.
