Polyquaternium 2

Polyquaternium-2 (CAS 63451-27-4) is a cationic quaternary ammonium polymer used in personal care and industrial formulations. Also marketed as Mirapol A-15 and PAQ 3.

Where is Polyquaternium 2 used?

• Hair care: deposits on damaged or chemically treated hair, improving combability, reducing static and enhancing wet and dry feel
• Skin care: improves skin feel and helps stabilize emulsions in lotions and cleansers
• Cosmetics: rheological contribution enhances the sensory profile
• Textile processing: softening and antistatic agent applied during finishing stages to modify fabric hand
• Industrial: reduces fiber-to-fiber friction
• Home care and industrial cleaning products improve surface wetting and provide residual conditioning on treated substrates.

Good to know: Its positive charge density drives substantivity to negatively charged surfaces, making it effective for conditioning, film formation and surface modification. Buyers should confirm active polymer concentration and viscosity specifications when evaluating lots for formulation compatibility.
