What is ISODODECANE used for?

Isododecane is a branched chain of twelve carbons and twenty-six hydrocarbons. It has long been made via petroleum resources but with increasing awareness, the industry is rapidly moving towards making plant-based and natural isododecane. This is achieved by converting starch and sugar residues and forestry waste into isobutene. This isobutene is then converted into Isododecane.
