Is PEG-10 Dimethicone Crosspolymer natural?

No. Silicone is zero by convention and the PEG crosslink units are petrochemical ethylene oxide.

INCI namePEG-10 Dimethicone Crosspolymer
FunctionLight Stabilizer · Viscosity Controlling
FeedstockThis crosslinked silicone elastomer is built from dimethyl…

How we scored it

Silicone crosspolymer (0, convention) with 10 mol ethylene oxide crosslinks (0, petrochemical) and an unspecified petrochemical crosslinker; total 0.0.
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

This crosslinked silicone elastomer is built from dimethyl siloxane and ethylene-oxide-derived PEG segments, both petrochemical. No natural-origin pathway is used.

In plain English

A silicone gel-forming ingredient used to control texture and stabilise sunscreens against light. It is entirely synthetic, made from silicone and petroleum-derived chemicals.

CosIng definition: Silicones and siloxanes, dimethyl, hydropoly(oxy-1,2-ethanediyl methyl, trimethylsilyl terminated, reaction products with unspecified cross-linking agent (10 mol EO average molar ratio)
