How we scored it

Lauroyl (natural, oleochemical) C12H23O 183.3 Da; propylene glycol fragment (petrochemical) C3H7O2 75.1 Da → 183.3/258.4 = 0.71.
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 lauric acid, a fatty acid from coconut or palm kernel oil, with propylene glycol derived from petrochemical propylene oxide. No significant bio-based propylene glycol route is used commercially.

In plain English

An ester made from lauric acid, a fatty acid from coconut or palm kernel oil, combined with propylene glycol. Used as a mild cleansing and skin-conditioning ingredient in wash-off products.
