Kojic Dipalmitate is an ester of Kojic Acid offering superior stability. Kojic Acid itself can be prone to instability with color-changes occurring over time, whereas Kojic Dipalmitate retains its stability for longer. It is used as a skin whitening ingredient and to reduce the appearance of age-spots.
Kojic Acid Dipalmitate (KAD) can tend to form a crystal precipitate in some cosmetic formulations. It is recommended to add Isopropyl Palmitate or Isopropyl Myristate to the oil phase containing KAD and heat to 80°C (167°F) and hold for 5 minutes until the KAD dissolves completely. Then add the oil phase to the aqueous phase and emulsify for about 10 minutes.
Typical usage rate: 1 – 4%
Appearance: White to almost white crystalline powder
Solubility: Insoluble in water, soluble in oil
