How we scored it

Natural plant polysaccharide (mannose/glucose polymer) per this site's convention: 100/100=1.00.
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

Glucomannan is extracted from the tubers of the konjac plant (Amorphophallus konjac), primarily grown in Asia. No synthetic manufacturing route is used commercially for this gum.

In plain English

A plant-based gum from konjac root that helps thicken products and condition skin. It is a natural carbohydrate polymer with no synthetic modification.

CosIng definition: Glucomannan is the polymer of Mannose containing side chains of glucose
