Is Behenyl Isostearate natural?

Yes. Behenyl alcohol and isostearic acid are both oleochemical fatty fragments from vegetable oil; esterification adds no petrochemical mass.

How we scored it

Ester of behenyl alcohol (C22) + isostearic acid (C18 branched), both oleochemical → 2/2 natural, 1.0.
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

Esterification of behenyl alcohol with isostearic acid, both sourced from vegetable fatty acids. A petrochemical Ziegler/oxo behenyl alcohol route exists; check supplier.

In plain English

An emollient wax ester that softens and conditions skin. Made from a long-chain fatty alcohol and a branched fatty acid, both typically from vegetable oils.
