Polyquaternium 2

Polyquaternium-2 (CAS 63451-27-4), also supplied under trade names such as Mirapol A-15 and PAQ 3, is a cationic quaternary ammonium polymer used across personal care and industrial formulations.

Its positive charge density drives substantivity to negatively charged surfaces, making it effective for conditioning, film formation, and surface modification. In hair care, it deposits on damaged or chemically treated hair.

This polymer improves combability, reduces static, and enhances wet and dry feel without weighing strands down. Skin care formulators incorporate it into lotions and cleansers where it improves skin feel and helps stabilize emulsions.

Through rheological contribution, it enhances the overall sensory profile of cosmetic products. In textile processing, it functions as a softening and antistatic agent applied during finishing stages to modify fabric hand.

It is also used to reduce fiber-to-fiber friction in industrial applications. Home care and industrial cleaning products use it to improve surface wetting and provide residual conditioning effects on treated substrates.

Polyquaternium-2 is typically supplied as an aqueous solution, with active content varying by grade and supplier. Both cosmetic-grade and technical-grade specifications are available to serve personal care and industrial markets.

Buyers should confirm active polymer concentration and viscosity specifications when evaluating lots for formulation compatibility. This ensures the material meets the necessary performance requirements for specific end-use applications.
