How we scored it
Stearyl alcohol (natural C18 fatty alcohol) esterified with stearic acid (natural C18 fatty acid); 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 esterifying stearyl alcohol and stearic acid, both typically derived from vegetable oils or animal tallow. No petrochemical route is standard for either fragment.
In plain English
An emollient, wax-like ester made from two natural fatty compounds, stearyl alcohol and stearic acid, used to thicken and soften creams.
Structure
octadecyl octadecanoate
