What Is Kojic Dipalmitate (KAD) Powder?
Kojic Dipalmitate (KAD) is obtained by double esterification of kojic acid and palmitic acid. The palmitic acid molecular chain protects the active hydroxyl groups of kojic acid, greatly improving stability against light, heat and metal ions, avoiding formulation yellowing and discoloration problems common to raw kojic acid.
After penetrating skin, KAD is hydrolyzed by skin esterase and releases active kojic acid, inhibiting tyrosinase activity to block melanin biosynthesis. It delivers sustained brightening and pigment-fading effects. Our cosmetic-grade KAD powder maintains stable batch-to-batch consistency. Each batch can provide full technical documents for cosmetic registration and formula R&D.
Core Advantages Of Our Kojic Dipalmitate (KAD) Powder
Greatly Improved Stability
Esterification modification solves kojic acid’s pain points: sensitive to light, heat and metal ions, easy to oxidize and turn yellow. KAD keeps stable in wide pH range, reduces finished-product color-change risk for commercial mass production.
Powerful Brightening & Depigmenting Capacity
Effectively inhibits tyrosinase activity, blocks melanin generation, fades dark spots, sun spots, melasma and post-inflammatory hyperpigmentation, evens dull and uneven skin tone.
Oil-Soluble With Superior Skin Penetration
Lipophilic molecular structure is compatible with cream, lotion, anhydrous balm and oil-based serum systems. Better skin barrier penetration than water-soluble kojic acid for long-acting brightening effect.
Antioxidant Protection
Neutralizes skin free radicals, reduces oxidative stress damage, brings auxiliary anti-aging benefits for brightening skincare formulas.
Broad Formulation Compatibility
Stable within pH 4.0-9.0, can be compounded with niacinamide, alpha arbutin, vitamin C derivatives and tranexamic acid derivatives for multi-path brightening synergy.
Reliable Quality & Full Technical Support
High purity ≥98%, strict batch inspection, support third-party independent lab testing. Provide COA, MSDS, TDS and practical formulation suggestions for your R&D team.
How Kojic Dipalmitate (KAD) Works In Cosmetic Formulations
KAD penetrates stratum corneum via lipophilic property. Inside skin tissue, skin esterase will hydrolyze KAD and release active kojic acid. It chelates copper ions of tyrosinase, suppresses tyrosinase catalytic activity, restrains melanocyte activation and melanin synthesis, so as to achieve brightening and pigment-reducing effect.
Note: KAD needs high-temperature dissolving in oil phase. Formulators need to control heating temperature, carry out compatibility test and finished-product safety & stability assessment to avoid crystal precipitation. Final effect depends on formula system, dosage and matched auxiliary ingredients.

Formulation Guide: Dosage, Dissolving & Critical Notes
Recommended addition range: 0.5%-2.0%. Adjust dosage according to product positioning and safety verification.
Dissolving method: KAD is oil-soluble, insoluble in water. Heat oil phase up to 95-100℃, add KAD powder under continuous stirring until fully dissolved, then proceed emulsification process; slow cooling is required to prevent crystal precipitation.
Suggested synergistic ingredients: Combine with niacinamide, alpha arbutin, TXC, vitamin C derivatives for multi-path brightening; add chelating agent EDTA-2Na to further improve system stability.
