How we scored it

Glucosamine (179 Da, fermentation/chitin-derived, natural) + acetyl cap from acetic anhydride (+42 Da, petrochemical) = 221 Da. 179/221 = 0.81.
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

Produced by acetylating glucosamine (from fungal fermentation or crustacean-shell chitin hydrolysis) with acetic anhydride. The acetyl cap is the only petrochemical contribution.

In plain English

A skin-conditioning amino sugar related to glucosamine, naturally found in skin. Made by adding an acetyl group, from a lab-made reagent, onto glucosamine derived from fermentation or shellfish shells.
