How we scored it
Lauryl C12H25 (natural, oleochemical) + sulfate SO4 (natural) + K+ (natural mineral) = 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 lauryl alcohol, typically from coconut or palm kernel oil, then neutralising with potassium hydroxide. No ethylene oxide is involved.
In plain English
The potassium salt of lauryl sulfate, made from coconut or palm-derived lauryl alcohol. Used as a foaming, cleansing ingredient in washes and shampoos.
Structure
potassium dodecyl sulfate
