Is Polyglyceryl-10 Decastearate natural?

Yes. Both glycerin and stearic acid are oleochemical feedstocks; ester/ether condensation sheds only water, which carries no petroleum mass.

How we scored it

Decaglycerol (from oleochemical glycerin, polymerised) fully esterified with stearic acid (oleochemical); only condensation water is lost, no petrochemical mass added.
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 polymerising vegetable-oil-derived glycerin into decaglycerol, then fully esterifying it with stearic acid from vegetable oil or tallow. No petrochemical reagent is incorporated.

In plain English

A skin-conditioning emulsifier made from glycerin (from vegetable oil) linked into a chain and fully combined with stearic acid, also from vegetable fat. Built entirely from plant-oil-derived materials.

CosIng definition: Decaester of decaglycerol and stearic acid
