How we scored it
C5H12 branched alkane; petroleum/natural-gas refining product, no oleochemical or mineral origin -> 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
Isopentane is obtained by fractional distillation of crude oil or natural gas liquids during petroleum refining. It is chemically identical regardless of end use, with no renewable feedstock route.
In plain English
A propellant and solvent used to help aerosol sprays and mousses dispense. It's a petroleum hydrocarbon, similar to the fuel components refined from crude oil and natural gas.
