How we scored it

Myristoyl C14H27O 211Da natural (fatty acid) + sarcosinate N(CH3)CH2COONa 110Da petrochemical (chloroacetic acid + methylamine route) → 211/321 = 0.66.
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 myristic acid (coconut/palm-derived). Sarcosine itself is conventionally synthesized from chloroacetic acid and methylamine, both petrochemical, rather than by fermentation.

In plain English

A mild cleansing surfactant made by combining myristic acid (a fatty acid from coconut or palm oil) with sarcosine, a lab-made amino-acid derivative. Used in foaming cleansers and shampoos.
