Mostly natural · ISO 16128

Is Soyamine natural?

Mostly. Fatty chain from soybean oil fatty acids is natural; amine nitrogen from industrial ammonia is counted non-natural, as with other fatty amines.

INCI nameSoyamine
CAS61790-18-9
FunctionAntistatic · Emulsifying Surfactant
FeedstockMade by converting soybean oil fatty acids to…

How we scored it

No formula supplied; estimated ~C17H35N from typical soybean fatty-acid chain distribution: ~251 Da natural fatty fragment + ~16 Da NH2 (ammonia, non-natural) ~= 0.93.
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 converting soybean oil fatty acids to nitriles with ammonia, then hydrogenating to primary fatty amines. The chain is oleochemical; the amine nitrogen is synthetic-ammonia derived.

In plain English

A fatty amine made from soybean oil fatty acids combined with ammonia. Used in small amounts as an antistatic agent and emulsifier in cosmetic and hair-care formulas.
