How we scored it
C5H12 straight-chain 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
Pentane is obtained by fractional distillation of crude oil or natural gas liquids during petroleum refining. It has no renewable feedstock route in commercial production.
In plain English
A propellant and solvent used in aerosol products to help them spray. It's a petroleum hydrocarbon refined from crude oil and natural gas, the same family as camping-stove fuel.
