Is Hexyl Isostearate natural?

Mostly. Isostearic acid is a natural branched fatty acid from oleic acid isomerisation; hexanol at C6 falls outside the C8+ oleochemical default.

How we scored it

Isostearoyl C18H35O 267.5Da (natural, branched oleochemical) + hexoxy C6H13O 101.2Da (petrochemical, below C8 default) = 368.6 → 267.5/368.6=0.73
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

Isostearic acid is made by clay-catalysed isomerisation of natural oleic/tall-oil fatty acids. Hexanol is usually a petrochemical alcohol rather than a coconut-oil fraction.

In plain English

A silky emollient ester for skin and hair products. Combines isostearic acid, a branched fatty acid made from natural vegetable oils, with hexanol, a short-chain alcohol usually from petroleum.
