How we scored it
C6H8O6 isoascorbic acid produced by fermentation of glucose, analogous to the ascorbic acid Reichstein/fermentation route => 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
Erythorbic Acid is manufactured by microbial fermentation of glucose or sucrose, analogous to the industrial route used for ascorbic acid. There is no significant petrochemical alternative route.
In plain English
An antioxidant that protects formulas from degradation, closely related to Vitamin C. It's produced by fermenting plant sugars, similar to how ascorbic acid is made.
