Diallyldimethylammonium chloride-hydroxyethyl cellulose copolymer (Polyquaternium-4) is a cationic conditioning polymer that combines the film-forming properties of hydroxyethyl cellulose with the substantivity of quaternary ammonium groups. It is primarily used in hair care formulations to improve combability, reduce static, and deliver conditioning benefits. SUNCHEM supports international buyers with this conditioning copolymer sourcing from qualified Chinese producers, with quality documentation, export coordination, and logistics support.
