CAS112-11-8
FormulaC21H40O2 · 324.5 Da
FunctionBinding · Emollient
FeedstockOleic acid is split from vegetable oils. Isopropanol…

How we scored it

Oleoyl C18H33O 265.5Da (natural) + isopropoxy C3H7O 59.1Da (petrochemical) = 324.5 → 265.5/324.5=0.82
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

Oleic acid is split from vegetable oils. Isopropanol is produced petrochemically from propylene by direct or indirect hydration.

In plain English

A lightweight emollient ester used in lotions, made from oleic acid, a vegetable-oil fatty acid, and isopropanol, a synthetic alcohol derived from petroleum.
