Kojic dipalmitate is a modified Kojic acid derivative, which not only overcomes the instability to light,heat and metal ions,but also maintains the inhibitory activity of tyrosinase and prevents the formation of melanin.
Kojic dipalmitate has stable chemical properties.As a fat-soluble skin whitening agent,kojic acid dipalmitate powder is more easily absorbed by the skin.
Skin care effect of Kojic Acid Dipalmitate:
1) Whitening: Kojic Acid Dipalmitate is more effectively inhibiting the activity of tyrosinase in the skin than curv acid, thereby inhibiting the formation of melanin, and has a good effect on whitening skin and sun protection.
2) Freckle: Kojic Acid Dipalmitate can improve skin pigmentation, and can fight against elderly spots, stretch marks, freckles and general pigmentation.
Kojic Acid Dipalmitate cosmetics reproduction guidelines:
Kojic Acid Dipalmitate is difficult to add to the formula, and it is easy to form crystal precipitation. In order to solve this problem, it is recommended to add palm acid glycopyrodidth or melmulate to the oily phase containing Kojic Acid Dipalmitate, heat the oil to 80℃, and heat for 5 minutes to Kojic Acid Dipalmitate to two seconds to make Kojic Acid Dipalmitate is completely dissolved, and then the oil phase is added to the water phase and emulsified for about 10 minutes. The pH value of the terminal products is around 5.0-8.0.
★What is the difference between Kojic Dipalmitate and Kojic Acid?
Kojic Acid is water-soluble but highly unstable — it easily oxidizes and turns brown in formulations. Kojic Dipalmitate is a lipophilic derivative (oil-soluble) that is much more stable against air, light, and heat. It provides a slower, more sustained tyrosinase inhibition, with less skin irritation. However, its whitening efficacy is slightly lower than pure kojic acid on a weight basis, but the stability advantage makes it preferred for most commercial serums and creams.
★Is Kojic Dipalmitate water-soluble or oil-soluble?
It is oil-soluble (lipid-soluble) with good fat solubility, suitable for addition in oil-phase or emulsified systems.
★What skincare products is Kojic Dipalmitate suitable for?
Whitening serum, spot-correcting cream, brightening lotion, anti-freckle mask, night cream, body whitening products, etc.
★What is the recommended usage rate in formulations?
The recommended addition concentration is 0.5%–3%, adjusted according to product positioning and efficacy requirements.
★What pH range is suitable for Kojic Acid Dipalmitate?
It is stable in pH 5.0–7.5 (weak acid to neutral), which is conducive to maintaining activity and efficacy.
★What ingredients can be compounded with Kojic Acid Dipalmitate?
It can be compounded with arbutin, vitamin C derivatives, niacinamide, tranexamic acid, retinol, hyaluronic acid to enhance whitening effect.
★Is Kojic Acid Dipalmitate more stable than kojic acid?
Yes. As a lipid-soluble derivative, Kojic Acid Dipalmitate has better stability, not easy to oxidize and discolor, more suitable for long-term storage and formula application.
★Is Kojic Dipalmitate approved for cosmetics in the EU, USA, and China?
EU: Kojic Dipalmitate is not specifically restricted. It is considered safe for cosmetic use (SCCS has no negative opinion). Common use concentration 0.5-3%.
USA: Allowed as an ingredient. No specific FDA prohibition.
China (NMPA): Listed in IECIC 2021 (INCI: Kojic Dipalmitate) with a maximum concentration of 3% for leave-on products. We provide full registration documents (COA, MSDS, TDS, PIF).
