How we scored it

Myristyl-O fragment (natural, oleochemical) 213.4 Da + PPG-3 chain (petrochemical propylene oxide) 175.2 Da = 388.6 Da; 213.4/388.6 = 0.55.
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 reacting myristyl alcohol, typically from coconut or palm kernel oil, with petrochemical propylene oxide. Assumes oleochemical-grade myristyl alcohol; petrochemical Ziegler/oxo-alcohol supply also exists.

In plain English

A skin-conditioning emollient made from a coconut- or palm-derived fatty alcohol combined with a petrochemical propylene oxide chain.
