Is Ceteareth-10 Phosphate natural?

Mostly not. Cetearyl alcohol and phosphate are natural-origin; the larger 10-mole ethoxylate chain is petrochemical, lowering the fraction versus the 5-mole version.

How we scored it

Cetearyl alcohol ~256 (natural) + 10 EO 441 (petrochemical) + phosphate ~80 (mineral, natural); natural 336/total 777=0.43.
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 phosphorylating cetearyl alcohol reacted with about 10 moles of petrochemical ethylene oxide. The phosphate group is mineral-derived.

In plain English

A cleansing ingredient similar to Ceteareth-5 Phosphate but with a longer petroleum-derived chain. It helps products foam and rinse away.

CosIng definition: C16-18 alcohols, ethoxylated, phosphates (10 mol EO average molar ratio)
