Is PEG-150/Decyl Alcohol/SMDI Copolymer natural?

Mostly not. PEG chain and the diisocyanate (SMDI) linker are petrochemical; only the decyl alcohol end-caps are oleochemical.

How we scored it

Assumed repeat unit: PEG-150 (150x44=6608Da) + 2 SMDI linkers (2x262=524Da) petrochemical; 2 decyl alcohol caps (2x158=317Da) natural -> 317/7449 = 0.04
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

A urethane-linked thickener made by joining PEG-150 (petrochemical ethylene oxide) to decyl alcohol (coconut/palm-derived) end-caps using SMDI, a petrochemical diisocyanate. The PEG and isocyanate dominate the mass.

In plain English

A synthetic thickener used in gels and lotions, built mainly from petroleum-derived ethylene oxide and a synthetic linker, with small coconut/palm-derived alcohol end groups.

CosIng definition: Poly(oxy-1,2-ethanediyl), .alpha.-hydro-.omega.-hydroxy-, polymer with 1,1'-methylenebis[4-isocyanatocyclohexane] and 1-decanol (150 mol EO avergae molar ratio)
