Is Glyceryl Isostearate natural?

Yes. Isostearic acid comes from isomerising natural oleic acid, and glycerin is a natural fat-processing byproduct; the ester keeps all atoms from both.

How we scored it

Isostearic acid (branched isomer of natural oleic acid, via clay-catalysed isomerisation) esterified with glycerin (natural); both fragments 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

Made by esterifying glycerin with isostearic acid, a branched fatty acid produced by clay-catalysed isomerisation of natural oleic acid from vegetable oils.

In plain English

An emollient ester made from plant-oil-derived fatty acid and glycerin. It softens skin and gives creams and lotions a light, non-greasy texture.

CosIng definition: Isooctadecanoic acid, monoester with glycerol
