How we scored it
Ester of triglycerol and isostearic acid (branched, from oleic acid dimerisation); both fragments natural. 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 isostearic acid derived from vegetable oleic acid. Both building blocks are natural and renewable.
In plain English
An emulsifier made by joining glycerin, three units, to isostearic acid, a branched fatty acid derived from vegetable oleic acid. Both building blocks are natural, renewable materials.
