How we scored it
Oxidation product of maltose (starch-derived sugar) via fermentation/enzymatic route; all-carbohydrate structure, fully natural-origin. 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
Made by oxidizing maltose, a disaccharide derived from starch hydrolysis, using enzymatic or fermentation processes. No petrochemical building blocks are involved.
In plain English
A sugar acid made by fermenting or enzymatically oxidizing maltose, a sugar derived from starch. Used in small amounts as a pH-buffering ingredient in skincare formulas.
