Polyquaternium-47

Polyquaternium-47 (CAS 197969-51-0) is a terpolymer-based quaternary ammonium compound derived from acrylamidopropyltrimethyl ammonium chloride, acrylic acid, and methacrylamide. Commercially available under trade names including Merquat 2000, Merquat 2001, and Merquat 2001N, it carries a net cationic charge that governs its functional behaviour across multiple formulation types.

In personal care formulations, Polyquaternium-47 deposits onto negatively charged hair and skin surfaces, improving wet combing and conditioning response without heavy buildup. In water treatment, its cationic charge neutralises suspended particulates, promoting flocculation and aiding downstream clarification. It also functions as a rheology modifier in aqueous systems, adjusting viscosity profiles in rinse-off and leave-on products.

Polyquaternium-47 is subject to REACH registration requirements for supply within the European Economic Area. It is available in liquid solution grades suited to direct incorporation into aqueous formulations. Procurement teams should confirm grade specification, active content, and packaging format directly with the supplier.
