Is Disodium Lauriminodipropionate natural?

Mostly. Coconut-derived lauryl amine is condensed with two petrochemical acrylic-acid units to build the amphoteric propionate arms, then neutralised with sodium.

How we scored it

C12H25-N(CH2CH2COONa)2 ~373 Da = lauryl+amine-N natural 229 Da (oleochemical fatty amine) + 2x acrylate-derived propionate 144 Da (petrochemical); 229/373 = 0.61.
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 neutralising with sodium hydroxide. The fatty amine portion is oleochemical; the propionate arms are synthetic.

In plain English

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