How we scored it

Cyclosiloxane/dimethylsiloxane copolymer (silicone). This site's convention: all silicones = 0.0 regardless of Si-O mineral backbone.
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 by hydrosilylation copolymerisation of cyclosiloxanes and vinyl-terminated dimethylsiloxanes, all petrochemically-processed silicone intermediates. No natural-origin route is used.

In plain English

A film-forming silicone polymer used in haircare and makeup for a smooth, long-wearing finish. It is a fully synthetic silicone copolymer.

CosIng definition: Cyclosiloxanes, dimethyl, polymers with dimethyl, methyl hydrogen siloxanes and vinyl-group terminated dimethylsiloxanes
