Mostly natural · ISO 16128

Is Oleoyl Sarcosine natural?

Mostly. Oleic acid fragment is oleochemical and natural; sarcosine is industrially made from petrochemical chloroacetate, so counts as non-natural.

INCI nameOleoyl Sarcosine
CAS110-25-8
FormulaC21H39NO3 · 353.5 Da
FunctionAntistatic · Cleansing
FeedstockMade by reacting oleic acid from vegetable oil…

How we scored it

Formula checks exactly: oleic amide (265 Da, natural) + sarcosine (88 Da, industrially made from petrochemical chloroacetate) = 353.5 Da; 265/353.5=0.75.
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 oleic acid from vegetable oil with sarcosine, an amino-acid derivative manufactured industrially from chloroacetic acid and methylamine. The fatty acid supplies most of the mass.

In plain English

A mild cleansing ingredient combining a vegetable-oil fatty acid with a lab-made amino-acid derivative. Used in shampoos and cleansers for gentle foaming.
