How we scored it

Silanetriol-based homopolymer end-capped with bisdextran ether; silicone-family structure → 0.0 by this site's convention despite dextran linkage.
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 by polymerizing a thiol/sulfo-functional silane and end-capping with dextran ether. Silicone backbone drives classification; no natural-only route.

In plain English

A silicone-based polymer linked to a sugar molecule, used in hair and skin products to add conditioning and a smooth feel.
