Is Polyglyceryl-3 Dimethicone natural?

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

How we scored it

Silicone (dimethicone backbone with polyglyceryl-3 side groups): silicones score 0.0 on this site whatever their side chains, so the glycerin-derived side groups 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: hydrosilylation of a hydrogen-dimethylsiloxane copolymer with allyl polyglyceryl-3 ether, the polyglycerol coming from vegetable glycerin. Chain length and graft count are not supplied, so the value is a grade-based estimate.

In plain English

A silicone-based emulsifier and conditioner in which a silicone backbone carries glycerin-derived side chains. It helps water and oil mix and adds slip to hair and skin products. The silicone is synthetic; the polyglycerol part comes from vegetable glycerin.

CosIng definition: Polyglyceryl-3 Dimethicone is the siloxane polymer that conforms generally to the formula:
