Function:
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.With the most advanced technology, kojic dipalmitate synthesized by our company has the most shallow color and the minimum impurity.
