How we scored it

Ester of phthalic acid (from benzene oxidation) and n-butanol (synthetic alcohol); both fragments petrochemical → 0/278 = 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

Produced industrially by esterifying phthalic anhydride (from benzene/o-xylene) with butanol, both petroleum refinery products. No natural route exists.

In plain English

A plasticiser and fragrance solvent made from petroleum-derived butanol and phthalic acid. It's a fully synthetic industrial chemical with no natural counterpart.
