Is Isostearyl Linoleate natural?

Yes. Isostearyl alcohol and linoleic acid are both oleochemical fatty fragments derived from natural oils; esterification adds no petrochemical mass.

How we scored it

Ester of isostearyl alcohol (oleochemical C18) + linoleic acid (vegetable-oil C18); both natural building blocks, ester = 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

Isostearyl alcohol, from dimerised/isomerised oleic acid, is esterified with linoleic acid from vegetable oils such as sunflower or safflower. Fully oleochemical feedstock.

In plain English

A lightweight, silky emollient made by combining two plant-oil-derived fatty ingredients, used in creams and lotions to soften skin without feeling greasy.
