Is Propyl Acetate natural?

No. Both n-propanol and the dominant commercial acetic-acid route are petrochemical; no natural fragment is present.

How we scored it

Propanol (petrochemical, propylene-derived) + acetic acid (dominant methanol-carbonylation route, petrochemical) -> 0/102.13 = 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

Propyl acetate is made by esterifying petrochemical propanol with acetic acid, which is dominantly produced by methanol carbonylation. A minor fermentation-derived acetic acid exists but is not the commercial norm.

In plain English

A synthetic solvent made from propanol and acetic acid, both mainly petrochemical-derived commercially. Used to dissolve ingredients and add a light fruity scent note in fragranced formulas.
