Is Sodium Lauriminodipropionate natural?

Mostly. Coconut-derived lauryl amine is condensed with petrochemical acrylic acid to form the propionate arms, one of which is partly neutralised with sodium.

How we scored it

C12H25-N(CH2CH2COOH)(CH2CH2COONa) ~351 Da = lauryl+amine-N+Na natural 206 Da (oleochemical fatty amine) + acrylate-derived arms 145 Da (petrochemical); 206/351 = 0.59.
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 reacting coconut/palm-kernel-derived laurylamine with acrylic acid (petrochemical) via Michael addition, then partially neutralising with sodium. The fatty amine portion is oleochemical; the propionate arms are synthetic.

In plain English

A mild, foam-boosting surfactant used in cleansing and hair products. It is made by reacting coconut-derived lauryl amine with a synthetic building block, then partly neutralising with sodium.
