Is Stearamine natural?

Mostly. Fatty amine from stearic acid via the nitrile route; the amine nitrogen from ammonia is conventionally non-natural.

How we scored it

Octadecyl fragment C18H37 253.5 Da (stearic-acid derived, oleochemical, natural) + NH2 16.0 Da (ammonia). 253.5/269.52 = 0.94.
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 from stearic acid, typically from vegetable oil or tallow, converted to the nitrile and hydrogenated to the amine using ammonia and hydrogen. Ammonia is sourced from natural gas.

In plain English

An antistatic ingredient made from a fatty acid found in vegetable oils or animal fat, converted into a fatty amine using ammonia.
