How we scored it
Ester of triglycerol (glycerin x3) and two stearic acid units; both fragments natural, condensation water not petroleum mass. 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 etherifying glycerin into a three-unit chain, then esterifying with two molecules of stearic acid. Both starting materials are oleochemical, vegetable or animal fat derived, and renewable.
In plain English
An emulsifier made by joining glycerin, three units, to two stearic acid molecules, a common vegetable or animal fatty acid. Both building blocks are natural, renewable materials.
