How we scored it

Sorbitan laurate core 346.5 Da (sorbitol+lauric acid, natural) + 44 EO x44=1936 Da petrochemical; 346.5/2282.5=0.15.
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 esterifying sorbitol with lauric acid from coconut oil to form sorbitan laurate, then reacting with petrochemical ethylene oxide. No alternative commercial route.

In plain English

A coconut-derived sorbitan ester reacted with ethylene oxide to make a mild cleansing surfactant used in washes and shampoos.

CosIng definition: Sorbitan, monododecanoate, poly(oxy-1,2-ethanediyl) derivs. (44 mol EO average molar ratio)
