How we scored it

Methylsilicone polymer, poly[oxy(methylsilylene)]; this site's convention scores all silicones 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

Manufactured synthetically from silicon metal via chlorosilane chemistry and polymerised. No natural-origin route is used commercially.

In plain English

A silicone used to condition skin and reduce static in hair care products. It's made through industrial silicon chemistry rather than from plant or animal sources.
