Is PPG-10 Cetyl Ether natural?

Mostly not. Cetyl fatty alcohol is oleochemical; 10 moles of petrochemical propylene oxide make up most of the molecule's mass.

How we scored it

Name indicates 10 mol PO; given formula (MW 300.5) matches only a 1-PO adduct, identical to PPG-30 Cetyl Ether's data. Cetyl alcohol 242.4+10 POx58.1=580.8 → 823.2 total; 242.4/823.2 → 0.29
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

Oleochemical cetyl alcohol is propoxylated with about 10 moles of petrochemical propylene oxide. The supplied formula and CAS number are identical to PPG-30 Cetyl Ether and likely represent a generic single-PO structure.

In plain English

An emollient made from a plant-derived fatty alcohol reacted with about ten units of propylene oxide, a petroleum-based chemical. Gives a light, smooth feel in lotions.
