How we scored it
Polyglycerol (10 mol glycerin, natural) diesterified with stearic acid (natural fatty acid); built only from natural blocks → 1275.7/1275.7 = 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 glycerin) with stearic acid from vegetable oils like palm or soy. No petrochemical route is used commercially.
In plain English
An emulsifier used to blend oil and water phases in creams. Made from polyglycerol (glycerin-based) esterified with stearic acid, a fatty acid typically from vegetable oils.
