How we scored it
Ascorbic acid from glucose fermentation (natural) + sodium (mineral counter-ion, natural). Both fragments natural.
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
Sodium Ascorbate is the sodium salt of ascorbic acid, or vitamin C, which is industrially produced from glucose via fermentation. The sodium comes from a mineral salt source.
In plain English
The sodium salt form of vitamin C, used as an antioxidant in skincare. It's made from glucose through a fermentation process and combined with a mineral sodium salt.
Structure
