How we scored it
Triglycerol (3 glycerol units, condensation, natural) + myristic acid (C14 oleochemical fatty acid) = fully natural fragments -> 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
Manufactured by esterifying triglycerol (self-condensed glycerol) with myristic acid, typically from coconut or palm kernel oil. Commercial polyglycerol esters have a distribution around the stated average degree of polymerization but remain oleochemical.
In plain English
An emulsifier that helps oil and water mix together in creams. It's made from glycerin and a coconut- or palm-derived fatty acid, both natural fat-derived building blocks.
CosIng definition: 1,2,3-Propanetriol, homopolymer, tetradecanoates (1:1) (3 mol glycerol average molar ratio)
