Kojic Dipalmitate




Skin lighteningKojic dipalmitate is more efficacious than kojic acid in inhibiting the activity of tyrosinase present in human skin so as to inhibit the melanin formation and produce excellent effects in whitening skin and in anti-suntan.
Solubility and
skin absorbance
Kojic acid dipalmitate is oil soluble and is more easily absorbed into skin when it is incorporated into a cream as compared with kojic acid

Formulation Suggestions
KAD is difficult to incorporate into the formulation, and it easily precipitates in the form of crystals. To solve this problem, it is suggested that isopropyl palmitate or isopropyl myristate be added to the oil phase, and heat the oil phase to 80℃ and keep at this temperature for about 5 minutes so that KAD completely dissolved, then add the oil phase to water phase for emulsification at the same temperature for 10 minutes or so. Generally, pH in final product is generally around 5.0—8.0.
Unlike Kojic Acid, which may not be compatible with some organic sunscreens and preservatives due to potential hydrogen bonding, Kojic Dipalmitate is compatible with virtually all ingredients and is especially advantageous for use in combination with sunscreens.
