How we scored it

Oleoyl C18H33O 265Da natural (fatty acid) + sarcosinate N(CH3)CH2COONa 110Da petrochemical (chloroacetic acid + methylamine route) → 265/375 = 0.71.
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 acylating sodium sarcosinate with oleic acid from vegetable or animal fat. Sarcosine itself is conventionally synthesized from chloroacetic acid and methylamine, both petrochemical, rather than by fermentation.

In plain English

A cleansing ingredient made by combining oleic acid (from vegetable or animal fats) with sarcosine, a lab-made amino-acid derivative. Used for its skin-conditioning effect in cleansing products.

CosIng definition: Sodium Oleoyl Sarcosinate is the sodium salt of oleoyl sarcosine that conforms to the formula
