Sodium Ascorbyl Phosphate is the stabilized (phosphorylated) sodium salt of L-ascorbic acid that does not degrade in formulas containing water. Esterification of ascorbic acid protect vitamin C from destruction by oxidation. Light-stable and oxygen-stable. Vitamin C is a well-known skin-whitening agent and to correct hyperpigmentation and age spots. Can improve appearance of aged and fragile skin. However, the use of other forms of Vitamin C (like Ascorbic acid, Sodium Ascorbate and L’ Ascorbic) is limited due to quike oxidation where the colour is changed and it’s potency lost. This is where SAP (Sodium Ascorbyl Phosphate) can overcome this shortcoming. With SAP, the stability of vitamin C product is highly improved. Once SAP is absorbed by skin, it quickly decomposes into Vitamin C, and exerts the physiological action of Vitamin C. It’s nontoxic, non-irritant, safe and reliable.
The photosensitivity and heat sensitivity of this product are much lower than Vitamin C. SAP can keep its color in a long time. And its stability in water is much more higher than Vitamin C. The product is stable when pH is more than 6.5 and it will be the stablest when the pH is equal to 6.5.
