How we scored it
C3H6O3 made by fermenting glycerin (natural) with Gluconobacter bacteria; a fermentation product, no petrochemical atoms added → 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
Produced by fermenting glycerin with Gluconobacter oxydans bacteria. No significant petrochemical synthetic route is used commercially today.
