How we scored it
Salt of two all-natural components: chitosan (crustacean-derived) and ascorbic acid (glucose fermentation). No petrochemical fragment present. 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
Chitosan from crustacean shells is combined as a salt with ascorbic acid made from fermented glucose. Both starting materials are natural-origin by convention.
In plain English
A skin-conditioning, antioxidant, film-forming ingredient made by combining chitosan, from crustacean shells, with vitamin C. Both starting materials come from natural or fermentation sources.
