How we scored it
Synthetic fluorinated industrial gas (1,1-difluoroethane); wholly 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
Produced industrially by hydrofluorination of petrochemical chlorinated-ethylene feedstocks. Used purely as an aerosol propellant.
In plain English
A propellant gas used in aerosol sprays. It's a synthetic fluorinated chemical manufactured from petrochemical feedstocks, with no natural origin.
