Property: Kojic dipalmitate is applied to cosmetics. It 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. As fat soluble skin whitening agent,it is easier to be absorbed by skin.


Features:
a. Skin Lightening. Compared with kojic acid, Kojic Dipalmitate markedly enhances the inhibitory effects on tyrosinase activity, which prohibits the formation of melanin.
b. Light and Heat Stability: Kojic Dipalmitate is light and heat stable, while kojic acid tends to oxidize over time.
c. pH Stability: Kojic Dipalmitate is stable within a wide pH range of 3-10, which provides flexibility to formulators.
d. Color Stability: Kojic Dipalmitate is stable to pH, light, heat and oxidation, and does not complex with metal ions, which leads to color stability.
