Sodium Ascorbate is a chemical compound, a salt derived from ascorbic acid (Vitamin C).

What it is used for and where

Food

It is an antioxidant used mostly in the food sector where it is labeled with the number E301 in food additives.

Medical

In dentistry it is used in teeth whitening (1) and as a binder against micro-infiltration (2).

Cosmetics

Antioxidant agent. Ingredient that counteracts oxidative stress and prevents cell damage. Free radicals, pathological inflammatory processes, reactive nitrogen species and reactive oxygen species are responsible for the ageing process and many diseases caused by oxidation.
