How we scored it
Diglycerol (glycerin-derived, natural) esterified with 2x isostearic acid (oleochemical C18 branched fatty acid, natural); ester built only from natural blocks → 699.1/699.1 = 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 esterifying diglycerol (from vegetable-oil-derived glycerin) with isostearic acid, a branched fatty acid produced by dimerization/isomerization of oleochemical fatty acids. No significant petrochemical route is used commercially.
In plain English
An emulsifier that helps blend oil and water in creams and lotions. It's made by combining glycerin with isostearic acid, a branched fatty acid typically derived from vegetable oils.
CosIng definition: Diester of diglycerol and isostearic acid
