Product information
Kojic Dipalmitate Powder is a lipophilic derivative of kojic acid, designed to overcome the instability issues of kojic acid in cosmetic formulations. It is highly stable under light, heat, and metal ion exposure, making it an ideal whitening ingredient for long-term use. Kojic Dipalmitate effectively inhibits melanin formation, improves uneven skin tone, and provides antioxidant protection. Its mild nature makes it suitable for sensitive skin and long-term application in skincare and cosmetic products.
