How we scored it
Oleyl alcohol (268 Da, oleochemical) esterified with erucic acid (339 Da, rapeseed-derived) minus H2O = 589 Da, all natural building blocks. 589/589 = 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 oleyl alcohol (from oleic acid, typically vegetable oil derived) with erucic acid (from rapeseed or mustard seed oil). Petrochemical (oxo/Ziegler) oleyl alcohol exists as a minor supplier alternative.
In plain English
An emollient ester that softens and smooths skin, made by combining two plant-oil-derived fatty ingredients: oleyl alcohol and erucic acid, the latter typically from rapeseed oil.
