Is PEG-20 Sorbitan Cocoate natural?

Mostly not. Sorbitan is sugar-derived and the coconut fatty acid ester is oleochemical; the 20 mol ethylene oxide chain is petrochemical.

How we scored it

Sorbitan 164 Da + lauric acid 200 Da - H2O 18 = 346 Da (natural) + 20 EO x44=881 (petro); 346/1227=0.28
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

Sorbitan comes from dehydrated sorbitol esterified with coconut fatty acids, then ethoxylated with 20 mol petrochemical ethylene oxide. Structurally equivalent to Polysorbate 20.

In plain English

A cleansing and emulsifying ingredient made from a sugar derivative esterified with coconut fatty acids, then combined with ethylene oxide, a petroleum-based building block.

CosIng definition: 1,4-Anhydro-D-glucitol, monoester with coconut fatty acids, poly(oxy-1,2-ethanediyl) derivatives (20 mol EO average molar ratio)
