100% natural origin · ISO 16128

Is Glucuronic Acid natural?

Yes. Derived directly from natural glucose by oxidation; the oxidising agent used contributes no mass to the final molecule.

How we scored it

Glucose (C6H12O6) oxidised at C6 to the carboxylic acid; oxidant/reagent atoms leave no mass, glucose carbon skeleton fully retained → 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

Commercially produced by oxidation of starch-derived glucose via chemical or enzymatic routes. Also occurs naturally as a metabolite; no petrochemical route is used.

In plain English

A humectant and chelating ingredient made by oxidising plant-derived sugar. It helps bind moisture and stabilise formulas, and traces entirely back to natural sugar feedstock.
