How we scored it

Polyglycerol-5 (glycerin, ether-linked, condensation water lost) esterified with lauric acid C12 (coconut-derived). No petrochemical fragment. 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

Vegetable glycerin is etherified into polyglycerol-5, then esterified with lauric acid from coconut or palm kernel oil. Standard oleochemical route; no petrochemical alternative.

In plain English

A plant-derived emulsifier made from glycerin and coconut-type lauric acid, which helps blend oil and water in a formula.
