Polyquaternium-47

Polyquaternium-47 (CAS 197969-51-0), commercially known as Merquat 2000, is a cationic terpolymer used in personal care and water treatment.

Where is Polyquaternium-47 used?

• Hair care: substantive conditioning and detangling by adsorbing onto the hair surface
• Skin care: enhances moisturizer spreadability and modifies the sensory profile of lotions and gels
• Water treatment: cationic charge density supports coagulation and flocculation of suspended solids
• Specialty coatings: wetting and surface modification agent where controlled deposition is required
• It functions as a conditioning agent and rheology modifier.

Good to know: This surface-active polymer deposits onto negatively charged substrates to improve feel, film formation, and process efficiency.
