Kojic acid dipalmitate is modified kojic acid derivative,which not only overcomes the instability to light, heat and metallic ion, but also keeps the inhibitory tyrosinase activity and prevents the forming of melanin.
Kojic dipalmitate owns stable chemical property. It will not turn yellow for oxidation, metallic ion, illumination and heating. As fat soluble skin whitening agent,it is easier to be absorbed by skin.
The recommended amount of kojic acid dipalmitate in cosmetics is 1-5%; the amount of whitening products is 3-5%.
1) Whitening:
Kojic acid dipalmitate is more effective than kojic acid in inhibiting tyrosinase activity in the skin, thereby inhibiting the formation of melanin, and has a good effect on whitening skin and sun protection.
2) Freckle removal:
Kojic acid dipalmitate can improve skin pigmentation and can fight age spots, stretch marks, freckles and general pigmentation.
