98% Kojic Acid Dipalmitate CAS 79725-98-7
What is Kojic Acid Dipalmitate?
Kojic Acid Dipalmitate (KAD): This is the best-known and most widely used kojic acid derivative. Two palmitic acid groups are attached to the kojic acid molecule. Its enhanced lipid solubility makes it far more stable to light, heat, and oxygen than pure kojic acid, and it resists discoloration. Its lipid solubility allows it to more easily penetrate the skin's lipid barrier and be absorbed. It is less irritating to the skin than pure kojic acid. Kojic acid dipalmitate is a highly effective whitening agent, improving the volatility of kojic acid and is now widely used. It effectively inhibits tyrosinase activity, blocking or delaying melanin formation.
Kojic acid dipalmitate boasts a high degree of stability not found in vitamin C, has no side effects, and possesses antioxidant properties. It quickly penetrates and is absorbed into the skin, softening the stratum corneum. It is often used in medical treatments to reduce facial blemishes, offering a whitening ingredient that combines effective, safe, and aesthetically pleasing skin.
Benefits of Kojic Acid Dipalmitate
-Kojic acid dipalmitate is a fat-soluble derivative of kojic acid that effectively inhibits tyrosinase activity, providing sun protection and brightening the skin, resulting in enhanced whitening effects. It also has excellent repairing properties for skin conditions such as melasma, age spots, and hyperpigmentation.
-Kojic acid dipalmitate not only overcomes kojic acid's instability to light and heat and discoloration when exposed to metal ions, but also does not affect the efficacy of additives in cosmetic systems, such as sunscreens, active ingredients, and preservatives, offering excellent compatibility.
-Kojic acid dipalmitate has a strong inhibitory effect on melanin production in human skin. It binds to copper ions, preventing the activation of tyrosinase by copper ions. It also inhibits the production of melanin, which can cause dark spots and freckles. It promotes skin metabolism and rapidly eliminates existing melanin, resulting in immediate whitening results.

Applications of Kojic Acid Dipalmitate
1. Whitening and Anti-Blemish Skincare Products
As a fat-soluble whitening agent, it effectively inhibits tyrosinase activity, blocking melanin production and improving chloasma, freckles, and hyperpigmentation. It is commonly used in whitening lotions, creams, serums, and masks, with a recommended addition level of 1%-5%.
2. Skin Repair and Conditioning
It promotes skin metabolism and accelerates melanin metabolism, helping to repair dullness and roughness caused by UV rays and inflammation, while enhancing skin radiance.
3. Sunscreen Auxiliary
It has a certain UV absorption capacity and can be used as a supplementary sunscreen ingredient to reduce UV damage to the skin and indirectly protect the skin from photoaging.
