How we scored it

Stearyl-O C18H37O 269.5 natural; propyl linker plus dimethylamino C5H12N 86.2 petrochemical (acrylonitrile, amines); 269.5 / 355.6 = 0.76.
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

Oleochemical stearyl alcohol is cyanoethylated with acrylonitrile, hydrogenated to the primary amine and methylated to the tertiary amine. Ziegler (petrochemical) stearyl alcohol exists, so the oleochemical chain is a supplier note.

In plain English

A fatty amine used in hair conditioners; after neutralising with an acid it coats hair and reduces static. The stearyl chain comes from palm or coconut oil, while the amine part is made from petrochemicals.
