Kojic acid dipalmitate is a modified kojic acid derivative, which overcomes the instability of kojic acid to light, heat and metal ions, and maintains the effect of inhibiting tyrosinase activity and blocking skin melanin formation, and this inhibition is stronger than kojic acid, making it a new generation of efficient whitening active agent.

Product performance: for the lipid solubility of kojic acid derivatives, it not only overcome the instability of kojic acid light, heat, and meet the disadvantage of metal ions, color, and because there is no hydroxyl groups in its molecular structure, not with preservatives in cosmetics system, sunscreen, or other active ingredients to form hydrogen bonds and influence the effect of these additives, the compound with an outstanding performance. As a fat-soluble additive in cosmetics, in addition to easier formulation, it can also be more effectively absorbed by the skin, bringing good moisturizing effect to the skin.
Usage: mainly used as cosmetic whitening additive. When used, add oil phase to use, the amount of 1~3% of the total.
Packing and storage: 1kg, aluminum foil bag, lined with plastic bag. Keep in a closed and cool place.
