Origin
2-methylundecane is a branched chain of twelve carbons and twenty-six hydrocarbons.
2-methylundecane 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 2-methylundecane.

2-methylundecane is both a solvent and an emollient which, in short, means that it helps keep your skin hydrated and disperses other appearance-enhancing ingredients across the skin.

2-methylundecane is used as a solvent in the cosmetic industry since it carries silicones and pigments for makeup super well.
