How we scored it
Polyglyceryl-2 (glycerin oligomer, natural) esterified with isostearic acid (branched C18 oleochemical, natural); both blocks 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 polyglycerol, from condensed vegetable glycerin, with isostearic acid derived from vegetable oil fatty acids. No petrochemical route is commercially significant.
In plain English
An emulsifier made by combining glycerin, condensed into a small chain, with isostearic acid, a branched fatty acid typically from vegetable oil.
