How we scored it
Cetyl/stearyl fatty alcohols (natural) + sulfate (natural mineral) + Na (natural) = 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 a blend of cetyl and stearyl alcohol, typically from coconut or palm oil, then neutralising with sodium. All building blocks are oleochemical or mineral.
In plain English
A cleansing and foaming ingredient made from coconut- or palm-derived fatty alcohols. It helps shampoos and cleansers lather and rinse away oil and dirt.
