How we scored it

Isobutanol (petrochemical synthetic alcohol per this site's convention) esterified with petrochemical acetic acid. 0/total = 0.0.
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

Isobutyl acetate is made by esterifying petrochemical isobutanol with acetic acid, itself mainly produced from petrochemical methanol. No natural-feedstock route is significant for this commodity solvent.

In plain English

A fruity-scented solvent used to dissolve other ingredients and as a minor fragrance component. Both the alcohol and acid used to make it are manufactured from petrochemical feedstocks.
