How we scored it

Myristyl C14H29 (natural, oleochemical) + sulfate-Na (natural) = 1.0, no ethoxylation.
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 myristyl alcohol, typically from coconut or palm kernel oil, then neutralising with sodium hydroxide. No ethylene oxide is involved.

In plain English

The sodium salt of myristyl sulfate, made from coconut or palm-derived myristyl alcohol. Used as a cleansing, foaming ingredient in washes.
