Polyquaternium-47

Polyquaternium-47 (CAS 197969-51-0), commercially known as Merquat 2000, is a cationic terpolymer used across personal care and water treatment applications. It functions as a conditioning agent and rheology modifier.

This surface-active polymer deposits onto negatively charged substrates to improve feel, film formation, and process efficiency. In hair care formulations, it provides substantive conditioning and detangling by adsorbing onto the hair surface.

By reducing friction and improving combability, it is a staple in high-performance shampoos and conditioners. Skin care formulators incorporate it to enhance moisturizer spreadability and modify the sensory profile of lotions and gels.

In water treatment, its cationic charge density supports coagulation and flocculation of suspended solids. This aids clarification in industrial process water and various wastewater management systems.

It also functions as a wetting and surface modification agent in specialty coating and treatment formulations where controlled deposition is required. This versatility makes it essential for diverse industrial applications.

Polyquaternium-47 is typically supplied as an aqueous solution for ease of handling. It is available in technical and cosmetic grades, with active content and viscosity specifications varying by supplier.

These specifications are tailored to suit either personal care or industrial end-use requirements. The polymer remains stable across a wide pH range, ensuring performance in complex chemical formulations.
