Is Sodium Decyl Sulfate natural?

Yes. Decyl alcohol is treated as an oleochemical C10 fatty alcohol, and sulfate plus sodium are mineral, both natural, with no ethylene-oxide content.

How we scored it

Decyl 157.28 (natural C10 oleochemical alcohol) + sulfate/sodium 103.05 (mineral, natural), no ether groups; 260.33/260.33 = 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 decyl alcohol from coconut or palm-kernel oil and neutralising with sodium hydroxide. A petrochemical Ziegler/oxo route to the C10 alcohol is a less common alternative worth a supplier check.

In plain English

A cleansing and foam-boosting surfactant made from a coconut or palm-derived fatty alcohol combined with sulfate and sodium. It helps products lather and remove oil and dirt.

CosIng definition: Sulfuric acid, monodecyl ester, sodium salt
