Kojic acid dipalmitate is modified kojic acid derivative,which not only overcomes the instability to light, heat and metallic ion, but also keeps the inhibitory tyrosinase activity and prevents the forming of melanin. Kojic acid dipalmitate owns stable chemical property. It will not turn yellow for oxidation, metallic ion, illumination and heating. As fat soluble skin whitening agent,it is easier to be absorbed by skin.
The recommended amount of kojic acid dipalmitate in cosmetics is 1-5%; the amount of whitening products is 3-5%
Function of Kojic acid dipalmitate
1.Kojic Acid Dipalmitate powder offers more efficacious skin lightening effects. Compared with kojic acid, kojic acid dipalmitate markedly enhances the inhibitory effects on tyrosinase activity, which prohibits the formation of melanin.
2.Kojic Acid Dipalmitate powder is light and heat stable, while kojic acid tends to oxidize over time.
3.Kojic Acid Dipalmitate is stable within a wide pH range of 4-9, which procides flexibility to formulators.
4.Kojic Acid Dipalmitate powder does not turn brown or yellow over time for two reasons. First, Kojic Acid is not stable to light and heat, and tends to oxidize, which results in color change (often yellow or brown). Second, Kojic Acid tends to chelate with metal irons, which often results in color change. On the contrary, kojic acid dipalmitate is stable to pH, light, heat and oxidation, and does not complex with metal ions, which lead to color stability.
Application of Kojic acid dipalmitate
1. In care, sun care, skin whitening/lightening, treatment for pigmentary disorders such as age spots etc.
2. Kojic Acid Dipalmitate offers more efficacious skin lightening effects.Kojic Acid Dipalmitate markedly enhances the inhibiting effects on tyrosinase activity, which prohibits the formation of melanin.
3. Kojic acid Dipalmitate used for all kinds of cosmetic products, for example, face masks, cream,soaps, lotion and other cleansers, and are most commonly used on the face, hands, and our body.
