How we scored it

Octyl-oxy C8H17O 129.2 Da (C8 fatty alcohol, coconut/palm kernel fraction, natural as for the site's C8-C22 fatty alcohols) + acetyl C2H3O 43.0 Da (petrochemical acetic acid); total C10H20O2 172.3 Da → 0.75.
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

Octanol from coconut or palm kernel oil esterified with acetic acid.

In plain English

A fruity-smelling ester made from a coconut-derived alcohol and acetic acid; about three quarters of it by weight comes from the natural alcohol.
