Product Name: Kojic acid dipalmitate Synonym: Kojic dipalmitate, KAD INCI NAME: KOJIC DIPALMITATE Molecular Formula: C38H66O6 Molecular Weight: 618.93 Appearance: White sheet crystals powder Purity: 99% CAS Number: 79725-98-7 EINECS number: 207-922-4 Supplier: ZHENYIBIO Kojic acid 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. In the cosmetics,Kojic dipalmitate for skin whitening and freckle removal.The recommended dosage of kojic dipalmitate powder in cosmetics is 1% to 5%;the amount of whitening products is 3-5%.

Trade name: ActiBiso-KA INCI name: Kojic Acid CAS: 501-30-4 Appearance: white powder Application: Kojic acid (ActiBiso-KA) is produced by the fermentation and purification of glucose or sucrose under the action of Kojic enzyme. Its whitening mechanism is to inhibit the activity of tyrosinase, at the same time inhibit the activity of n-hydroxyindoleate (dhica) oxidase and block the polymerization of dihydroxyindole (DHI). It is a rare single whitening agent that can simultaneously inhibit a variety of enzymes. Kojic acid is an excellent whitening and light spot ingredient. After decades of research and application, it is a classic ingredient that has been tested. As long as the dosage is within a certain range, there is no safety problem and no sensitization reaction will be caused. If the whitening effect brought by VC is expressed by transparency, the effect Kojic acid brings to you is the feeling of smooth milky white. The combination of the two is the best.
