How we scored it
Polyglycerin (glycerin oligomer) esterified with stearic acid; both natural building blocks, condensation water not counted -> 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 splitting) and esterifying with stearic acid (vegetable or tallow-derived). No petrochemical fragment is introduced.
In plain English
A plant-based emulsifier made from glycerin and stearic acid (a vegetable fatty acid), used to blend oil and water in creams.
CosIng definition: 1,2,3-Propanetriol, homopolymer, monooctadecanoate
