Mostly petroleum · ISO 16128

Is PEG-4 Laurate natural?

Mostly not. The fatty lauric acid chain is coconut/palm-derived; the 4-unit ethylene-oxide glycol chain is petrochemical.

How we scored it

Lauroyl (natural, C12H23O = 183.3 Da) + tetraethylene glycol chain (petrochemical EO, 193.2 Da). 183.3/376.5 = 0.49.
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-4 Laurate is made by reacting lauric acid, typically from coconut or palm kernel oil, with tetraethylene glycol derived from petrochemical ethylene oxide. Roughly half the molecule's mass comes from each source.

In plain English

A mild surfactant that helps cleanse and emulsify in shampoos and washes. About half of it comes from coconut/palm fatty acid, and half from a petroleum-derived glycol chain.
