Is Polyglyceryl-3 Diisostearate natural?

Yes. Glycerol is natural and isostearic acid is a branched fatty acid made by isomerising natural oleic acid; catalysts leave no mass.

How we scored it

Triglycerol (glycerol ×3, condensation) + 2 isostearic acid − 2 H2O; all fragments natural (oleochemical). 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

Glycerol (from fats/oils or fermentation) is self-condensed into triglycerol, then esterified with isostearic acid, a branched-chain fatty acid produced by clay-catalysed isomerisation of vegetable oleic acid. No petrochemical feedstock is used.

In plain English

An emulsifier that helps oil and water mix, used in creams and lotions. Made from glycerin (a sugar-derived alcohol) linked to isostearic acid, a branched fatty acid produced from vegetable oleic acid. Fully plant-derived.
