How we scored it
Polyglycerol (glycerin homopolymer, natural) diesterified with oleic acid (natural fatty acid); built only from natural blocks → 769.1/769.1 = 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 (condensed from vegetable-oil-derived glycerin) with oleic acid from vegetable oils such as sunflower or olive. No petrochemical route is commercially used.
In plain English
An emollient and emulsifier that helps oils and water mix in creams and lotions. It's made from polyglycerol (built from glycerin) esterified with oleic acid, a fatty acid commonly from vegetable oils.
