How we scored it

Methanol (petrochemical) + 2× propylene oxide (PPG-2, petrochemical) — both fragments petrochemical → 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

PPG-2 Methyl Ether is made by propoxylating methanol with 2 moles of propylene oxide, both petrochemical feedstocks. No natural-origin route exists for this synthetic solvent.

In plain English

A synthetic solvent made from methanol and propylene oxide, both derived from petrochemicals.
