How we scored it
Polyglycerol-6 (glycerin-derived, natural) esterified with isostearic acid (branched C18, natural oleochemical feedstock). 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
Polyglycerol-6 is made by etherifying vegetable glycerin; isostearic acid by isomerizing/dimerizing natural oleic acid. Standard oleochemical route.
In plain English
A plant-derived emulsifier made from glycerin and a branched natural fatty acid, used to blend oil and water.
CosIng definition: 1,2,3-Propanetriol, homopolymer, isooctadecanoates (1:1) (6 mol glycerol average molar ratio)
