Is PPG-3 Caprylyl Ether natural?

Mostly not. Natural C8 fatty alcohol is etherified with three petrochemical propylene-oxide units, which make up over half the mass.

How we scored it

Caprylyl (C8) alcohol, assumed oleochemical, minus H = 129.2 Da / total [130.2+3×58.08=304.5] Da = 0.42; 3 PO units petrochemical.
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

Caprylyl (octyl) alcohol, assumed oleochemical (coconut/palm-kernel) for cosmetic grade, is propoxylated with petrochemical propylene oxide. A petrochemical oxo-alcohol route for the caprylyl portion also exists; supplier verification recommended.

In plain English

A solvent and foam-boosting ingredient. A fatty alcohol, usually from coconut or palm oil, is combined with a short chain of petroleum-derived propylene oxide.

CosIng definition: PPG-3 Caprylyl Ether is the polypropylene glycol ether of caprylic alcohol; Poly(oxy-1-methyl-1,2-ethandiyl), alpha-octyl-omega-hydroxy- (3 mol PO average molar ratio)
