How we scored it

Cyclic siloxane homopolymer grafted with allyl glyceryl ether side chains; this site's convention rates all silicones 0.0 regardless of organic grafts.
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

Produced from cyclic methyl siloxanes (ultimately from mineral silicon) reacted with an allyl glyceryl ether via hydrosilylation. Treated as entirely non-natural under the site's blanket silicone convention.

In plain English

A silicone-based conditioning polymer used in haircare to add shine and smoothness. Despite containing a glycerin-like fragment, it is classified as entirely non-natural under this site's silicone policy.
