Is Laureth-3 Phosphate natural?

Mostly. Lauryl alcohol is oleochemical and the phosphate group is mineral-derived; only the three ethylene-oxide units are petrochemical.

INCI nameLaureth-3 Phosphate

How we scored it

Dodecanol (natural, oleochemical) 186 Da + 3x44 Da EO (petrochemical) 132 Da + phosphate (mineral, natural) 80 Da = 398 Da; 266/398=0.67.
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 coconut/palm-kernel-derived lauryl alcohol, ethoxylated with petrochemical ethylene oxide, then phosphated. No alternative route.

In plain English

A gentle cleansing surfactant made from coconut-derived lauryl alcohol, ethoxylated and finished with a phosphate group. Used in facial cleansers for mild oil removal.

CosIng definition: Poly(oxy-1,2-ethanediyl), .alpha.-dodecyl-.omega.-hydroxy-, phosphate
