Ascorbyl Tetraisopalmitate structure
Benefits
· | Stabilized oil-soluble vitamin C derivative. |
· | Excellent percutaneous absorption and effectively converts into free vitamin C in the skin to perform various physiological functions; Polyolprepolymer-2 (PP-2) can further enhance VC-IP to penetrate into skin. |
· | Skin Lightening: inhibits activity of intracellular tyrosinase and melanogenesis The results are dose-dependent. |
· | UV protection / anti-stress: reduces UV-induced cell / DNA damage |
· | Anti-Aging: significantly promotes collagen synthesis, inhibits the activity of collagen degrading enzyme; Revitalize cell activity and proliferate human fibroblasts. The results are dose-dependent. |
· | Antioxidant:prevents lipid peroxidation and skin aging; SOD-like activity |
Formulation Guides
· | Use processing not exceeding pH 6 |
· | Add VC-IP into formulation right before the adjustment. |
· | The use of chelating agents and anti-oxidants (tocopherol) in the formulation is recommended. |
· | Surfactants with long chain polyoxyethylenes can stabilize the system, strengthening the interfacial membrane. |
· | Avoid heating for long periods of time. |
