How we scored it

Hydroxy-terminated silicone polymer; this site's convention sets all silicones to 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

A high-molecular-weight silicone polymer made from silicon metal via the chlorosilane hydrolysis route. This site's convention scores all silicones 0.0 regardless of the mineral origin of silicon.

In plain English

A silicone polymer that adds shine and smoothness to hair and skin products. Manufactured industrially from silicon metal. Classed here as non-renewable by this site's convention, despite its mineral starting point.
