Is PEG-10 Soyamine natural?

Mostly not. Ethoxylated fatty amine. The soybean alkyl chain is natural; the amine nitrogen from synthetic ammonia and the 10 ethylene-oxide units are petrochemical.

How we scored it

Soy alkyl (oleyl proxy) chain C18H35 251.5 Da (natural); nitrogen 14.0 Da (synthetic ammonia) + 10×EO 440.5 Da + 2 terminal H (petrochemical); total 708.0 Da → 0.36. Same method as PEG-5 Soyamine and PEG-15 Cocamine.
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

Soybean fatty amine reacted with about 10 mol of ethylene oxide.

In plain English

A cleansing and emulsifying ingredient made from soybean-oil-derived fatty amine reacted with ethylene oxide, used to blend oil and water in cleansers.

CosIng definition: Amines, soya alkyl, ethoxylated (10 mol EO average molar ratio)
