How we scored it

Cetyl alcohol C16H33O 241 Da (natural) + 2-ethylhexanoyl C8H15O 127 Da (petrochemical) = 369 Da; 241/369 = 0.65.
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 oleochemical cetyl (C16) alcohol, typically from coconut or palm oil, with petrochemical 2-ethylhexanoic acid. The fatty alcohol carries most of the molecule's mass.

In plain English

A lightweight, non-greasy emollient ester that gives a silky feel to lotions and sunscreens. Made by combining a coconut or palm-derived fatty alcohol with a petroleum-derived branched acid.
