How we scored it

C16H32 224.4 from isobutene oligomerisation; all carbon petrochemical; 0/224.4 = 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

Dominant route oligomerises refinery or cracker isobutene to a C16 olefin. Bio-isobutene exists only at pilot scale.

In plain English

A light, fast-spreading hydrocarbon solvent and emollient that leaves a dry, non-oily feel. It is made from petroleum-derived isobutene.

CosIng definition: Isohexadecene is a branched chain aliphatic hydrocarbon containing 16 carbons.
