How we scored it

Linoleic acid C18H32O2 (vegetable oil, natural) + ethanol C2H6O (fermentation, natural), esterified, -H2O = C20H36O2; both natural. 1.0.
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 linoleic acid (from sunflower, safflower or similar seed oil) with ethanol. Fermentation ethanol is assumed as the default source, consistent with this site's method excluding ethanol from its synthetic-alcohol list.

In plain English
