| CAS 108910-78-7 | English name L-Ascorbic acid phosphate magnesium salt |
| Molecular formula C6H8Mg3O14P2 | Exact mass 437.89400 |
| Molecular weight 438.98200 | PSA 299.34000 |
| Description: VC Magnesium phosphate (map) is a salt that remains neutral and stable at pH. The phosphate group is located at the second point of the ring. On the one hand, it can protect it from oxidation reactions, on the other hand, it can prevent its volatilization and oxidation. Therefore, their efficacy depends on whether they are converted to ascorbic acid. Under alkaline conditions, L-ascorbic acid has only a very low passive permeability, while map more easily penetrates into the dermis and converts to L-ascorbic acid, the difference in permeability may be due to the fact that L-ascorbic acid is hydrophilic, while map is lipophilic. In in vitro studies of human fibroblasts, map and L-ascorbate have the same ability to stimulate collagen synthesis. However, SAP requires at least 10 times the concentration to achieve the same effect. It is superior to vitamin C in comparison to the stability map, and transdermal absorption is far less than vitamin C. MAPo has been shown to be able to convert back to vitamin C, but there is no evidence that sodium ascorbate phosphate (SAP) can convert back to vitamin C. |
