1. Skin Lightening: Kojic Acid Dipalmitate offers more efficacious skin lightening effects. Comparing with Kojic Acid, Kojic Dipalmitate markedly enhances the inhibitory effects on tyrosinase activity, which prohibits the formation of melanin. As a oilsoluble skin whitening agent, it is easier to be absorbed by skin.
2. Light and Heat Stability:Kojic Acid Dipalmitate is light and heat stable, But Kojic Acid tends to oxidize over time.
3. pH Stability: Kojic Acid Dipalmitate is stable within a wide pH range of 4-9, which provides flexibility to formulators.
4. Color Stability: Kojic Acid Dipalmitate does not turn brown or yellow over time,becuase Kojic Acid Dipalmitate is stable to pH, light, heat and oxidation, and does not complex with metal ions, which lead to color stability.
