How we scored it

Mixture of cyclic dimethyl siloxanes (D4-D6); 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 from silica-derived silicone monomers polymerised and distilled into cyclic D4-D6 siloxane rings. This site's convention treats all silicones as 0.0 regardless of the mineral origin of the Si-O backbone.

In plain English

A lightweight, fast-evaporating silicone fluid that gives a silky after-feel and helps other ingredients spread. Manufactured from silicone polymers derived from silica sand, not from plants.

CosIng definition: Cyclomethicone is a generic name for a mixture of cyclic dimethyl polysiloxane compounds that conform to the formula, where n has a value between 4 and 6.
