How we scored it

Isostearyl alcohol (branched C18, oleochemical) esterified with palmitic acid (C16, oleochemical); both natural, no petrochemical fragment.
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

Made by esterifying isostearyl alcohol, from isomerised oleic acid, with palmitic acid, both from vegetable oils. No petrochemical route is typical.

In plain English

A light, silky oil that softens skin and improves spreadability in creams and lotions. Made from fatty acids and alcohols derived from vegetable oils.
