How we scored it
Triglycerol (condensed glycerin) esterified with oleic acid; both natural building blocks, condensation water leaves no petrochemical residue, giving 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
Polyglyceryl-3 Oleate is made by esterifying triglycerol (polymerised glycerin) with oleic acid from vegetable oil. Both feedstocks are natural-origin.
In plain English
An emulsifier made from plant glycerin linked together and combined with oleic acid, a fatty acid from vegetable oil. It helps blend oil and water in formulas.
CosIng definition: ester of triglycerol and oleic acid
Structure
[3-[3-(2,3-dihydroxypropoxy)-2-hydroxypropoxy]-2-hydroxypropyl] (Z)-octadec-9-enoate
