Is Sodium Lauroyl Sarcosinate natural?

Mostly. Lauric acid is coconut-derived; sarcosine is industrially made mainly from petrochemical chloroacetic acid and methylamine.

INCI nameSodium Lauroyl Sarcosinate
CAS137-16-6
FormulaC15H28NNaO3 · 293.38 Da
FunctionAntistatic · Cleansing
FeedstockAmide of coconut-derived lauric acid with sarcosine (N-methylglycine),…

How we scored it

Lauroyl C12H23O 183.3 Da (natural) + Na 23.0 Da (natural) = 206.3 Da vs sarcosinate C3H5NO2 87.1 Da (petrochemical, chloroacetate+methylamine route). 206.3/293.4=0.70.
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.

How it’s made

Schotten–Baumann acylation. Each curved arrow moves one electron pair, and the film ends on the score above.

Where it comes from

Amide of coconut-derived lauric acid with sarcosine (N-methylglycine), manufactured mainly from sodium chloroacetate and methylamine rather than isolated from natural protein. The sodium counter-ion is mineral-natural.

In plain English

A foaming cleanser made from coconut-derived lauric acid joined to sarcosine, an amino-acid-like compound usually made synthetically. Used in toothpastes and mild shampoos to boost foam.
