How we scored it
Decaglycerol C30H62O21 758.8 + 4 oleic acid 1129.9 - 4 water 72.1 = 1816.6 Da (C102H190O25); all natural, so 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
Dominant route polymerises glycerin to decaglycerol and esterifies it with four oleic acid units from vegetable oil. No petrochemical route is used commercially.
In plain English
An emulsifier and skin conditioner made by attaching four oleic acid chains to polyglycerin. Both parts come from vegetable oils, and it helps oils and water mix and softens skin.
CosIng definition: Tetraester of decaglycerol and oleic acid
