About

Polyquaternium Crosspolymer-2 is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Polyquaternium Crosspolymer-2 is a crosslinked polymer of PEG-4 methacrylate, dimethylacrylamide, and related monomers, quaternised with trimethylammonium groups. Its crosslinked structure means it is not absorbed through the skin, making it exceptionally mild. It is used as a hair and skin conditioning agent in leave-on and rinse-off formulations. No specific EU restrictions apply to this polymer class beyond general cosmetic safety requirements under Regulation 1223/2009.
