Is PEG-15 Hydrogenated Tallow Amine natural?

Mostly not. Ethoxylated fatty amine. The hydrogenated tallow alkyl chain is natural; the amine nitrogen from synthetic ammonia and the 15 ethylene-oxide units are petrochemical.

How we scored it

Hydrogenated tallow alkyl (stearyl proxy) chain C18H37 253.5 Da (natural); nitrogen 14.0 Da (synthetic ammonia) + 15×EO 660.8 Da + 2 terminal H (petrochemical); total 930.3 Da → 0.27. Same method as the PEG-n Cocamine and Stearamine entries.
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

Hydrogenated tallow fatty amine reacted with about 15 mol of ethylene oxide.

In plain English

A fatty amine from hardened animal tallow heavily reacted with ethylene oxide, used as a surfactant. Most of its final weight comes from petrochemical ethylene oxide rather than the tallow it started from.

CosIng definition: Amines, hydrogenated tallow alkyl, ethoxylated (15 mol EO average molar ratio)
