Mostly petroleum · ISO 16128

Is DEA-Oleth-10 Phosphate natural?

Mostly not. Oleyl alcohol and phosphate are natural; the ten ethylene-oxide units and diethanolamine counter-ion are petrochemical, per this site's TEA/DEA convention.

How we scored it

Using CosIng-confirmed 10 EO (given formula represents a simplified 1-EO structure): oleyl 268.5 + phosphate-O 80.0 (natural) = 348.5; 10 EO 440.5 + DEA 105.1 (both petrochemical) = 545.6; 348.5/894.1 = 0.39
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 from vegetable-derived oleyl alcohol, heavily ethoxylated with petrochemical ethylene oxide, phosphorylated, then neutralised with petrochemical diethanolamine.

In plain English

An emulsifying and cleansing ingredient made from a plant-derived fatty alcohol combined with several synthetic processing steps. Used in cleansers and emulsions to help oil and water mix.

CosIng definition: (Z)-9-Octadecanol, ethoxylated, phosphates, bis(2-hydroxyethyl)ammonium salts (10 mol EO average molar ratio)
