Mostly petroleum · ISO 16128

Is PEG-8 Laurate natural?

Mostly not. The lauric acid chain is coconut/palm-derived; the longer 8-unit ethylene-oxide chain is petrochemical and dominates the mass.

How we scored it

Lauroyl (natural, 183.3 Da) + octaethylene glycol chain (petrochemical, 369.4 Da). 183.3/552.7 = 0.33.
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

PEG-8 Laurate esterifies coconut/palm-derived lauric acid onto a longer, 8-unit petrochemical ethylene oxide chain. The larger glycol chain lowers the natural fraction compared with shorter PEG laurates.

In plain English

A surfactant and emulsifier used in cleansers. About a third of its weight comes from coconut/palm fatty acid; the rest is a longer petroleum-derived glycol chain.
