How we scored it

Ester of prenol (terpene alcohol) and acetic acid; both fragments commercially petrochemical-sourced for this aroma chemical (prenol from isoprene/isobutylene, acetyl from acetic anhydride), no significant natural-isolation route → 0/128 = 0.00.
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 prenol (3-methyl-2-buten-1-ol, typically from petrochemical isoprene or isobutylene) with acetic anhydride (an petrochemical acetyl cap). No commercially significant natural-isolation route exists for this fragrance ester.

In plain English

A fragrance ingredient with a fruity, green scent, produced synthetically by combining a terpene alcohol with acetic anhydride. Used to perfume cosmetics and personal care products.
