HYDROGENATED DICYCLOPENTADIENES/METHYL STYRENES/INDENE COPOLYMER

78

Safety score · 0–100

Fine

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

A fully hydrogenated hydrocarbon polymer used to thicken creams and lotions and add some structural feel. Hydrogenation removes reactive double bonds, leaving an inert polymer — main caveat is monomer-residue purity for the styrene/indene starting materials.
