Kojic acid Dipalmitate

Kojic acid Dipalmitate is a modified Kojic acid derivative that overcomes Kojic acid's instability to light, heat and metal ions while maintaining Kojic acid's inhibitory tyrosinase activity and blocking skin melanin formation. And this inhibition is stronger than Kojic acid.

Kojic acid Dipalmitate is chemically stable and does not yellow due to oxidation, metal ions, light and heat. Due to the absence of hydroxyl groups in its molecular structure, it does not form hydrogen bonds with preservatives, sunscreens or other active ingredients added to the cosmetic system to affect the efficacy of these additives, and has good compounding properties. Kojic acid Dipalmitate is a fat-soluble active agent that, in addition to being easier to formulate, also provides good moisturization to the skin.
