How we scored it
Polyglycerin esterified with oleic acid; both natural building blocks -> 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 polymerising glycerin (from vegetable oil) and esterifying with oleic acid (vegetable oil-derived). No petrochemical fragment is introduced.
