How we scored it

Myristyl alcohol (C14, natural) alkoxy 213.4 Da; propionic acid (petrochemical oxo-process) acyl 57.1 Da; 213.4/270.5=0.79
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 esterifying myristyl alcohol (oleochemical) with propionic acid, mainly manufactured from petrochemical ethylene via the oxo-process. A minor fermentation route to food-grade propionic acid exists but is not typical for ester feedstock.

In plain English

An emollient ester that smooths skin, made from a coconut or palm-derived fatty alcohol combined with propionic acid, a small acid mostly produced from petrochemical feedstock.
