How we scored it
Ascorbic acid (glucose fermentation, natural) phosphorylated (phosphate = natural mineral fragment) and formed into the magnesium salt (natural mineral ion) = 1.0
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Made by phosphorylating fermentation-derived ascorbic acid (Vitamin C) and forming the magnesium salt. Both the phosphate group and magnesium counter-ion are mineral, natural-origin fragments.
In plain English
A stable, gentle form of Vitamin C used for its antioxidant, brightening properties. It is made from fermented-sugar-derived vitamin C combined with mineral phosphate and magnesium.
CosIng definition: Ascorbyl monophosphate magnesium salt
