How we scored it

Cellulose backbone (natural) sulfated and neutralized with sodium; sulfate and Na are natural per counter-ion convention.
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 treating wood-pulp or cotton cellulose with a sulfating agent, then neutralizing with sodium hydroxide. The sulfating reagent itself leaves no petrochemical mass behind.

In plain English

A thickening and stabilizing ingredient made by attaching sulfate groups to cellulose (plant fiber) and neutralizing with sodium. Cellulose typically comes from wood pulp or cotton.

CosIng definition: Cellulose, hydrogen sulfate, sodium salt
