Is Sodium Lauroyl Glycinate natural?

It depends. The coconut fatty chain and sodium are natural origin; the glycine may be fermented or synthetic.

Why the score varies

This ingredient is made commercially by more than one route, and ISO 16128 scores the feedstock actually used. Without a supplier certificate of origin the value cannot be claimed.

Ask your supplier. A batch-specific certificate of origin or bio-based carbon test (ASTM D6866) settles which route applies.

How we scored it

Glycine is route-dependent on this site (see Glycine). Sodium lauroyl glycinate 279.4 Da = lauroyl 183.3 Da (coconut, natural) + glycinate C2H3NO2 73.1 Da (route-dependent) + Na 23.0 Da (mineral). Natural glycine: 1.0; synthetic glycine: 0.74.
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

Lauric acid from coconut oil, glycine (natural or synthetic) and sodium hydroxide.

In plain English

A mild cleansing surfactant made by combining coconut-derived lauric acid with the amino acid glycine, used in cleansers and shampoos.

CosIng definition: Sodium Lauroyl Glycinate is the organic compound.
