Is Polyglyceryl-3 Disiloxane Dimethicone natural?

No. Classed as a silicone, so it scores 0.0 whatever its side chains; the plant glycerin in the polyglyceryl-3 grafts is not credited, because only protein bound into a silicone counts.

How we scored it

Silicone (dimethicone backbone with polyglyceryl-3 grafts): silicones score 0.0 on this site whatever their side chains, so the glycerin-derived grafts are not credited; only protein bound into a silicone is (Polysilicone-14/-16). 0 / total = 0.00.
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

Dominant route is platinum-catalysed hydrosilylation of an allyl polyglyceryl ether (allyl alcohol plus glycerin or glycidol) onto a SiH-functional siloxane. Exact graft density is not published, so the natural share is an estimate.

In plain English

A silicone-based emulsifier and conditioning agent in which a short chain of three glycerin units is attached to a dimethicone backbone, helping oil and water phases mix and giving a smooth feel. The glycerin part is plant-derived; the silicone part is synthetic.

CosIng definition: Siloxane polymer of triglycerol
