How we scored it

Coconut fatty alcohol (natural, oleochemical) sulfated with mineral SO3 (natural); no ethoxylation present -> 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 sulfating coconut fatty alcohol directly with mineral sulfur trioxide, without any ethoxylation step. Both the fatty chain and sulfate group are natural-origin.

In plain English
