Polyquaternium 55

Polyquaternium-55 (CAS 306769-73-3) is a cationic conditioning polymer for personal care and industrial textile applications.

Where is Polyquaternium 55 used?

• Hair care: detangling, frizz control and improved combability in rinse-off and leave-on products
• Skin care: smooth, non-tacky feel with humectant performance in lotions and serums
• Textile processing: softening and antistatic finish on fabric substrates
• Paper and leather treatment: modifies surface properties and substrate-coating interaction
• It deposits onto negatively charged surfaces for conditioning, film formation and moisture retention.

Good to know: Formulators select it for compatibility with anionic surfactant systems and surface-feel modification without buildup. Buyers should confirm active polymer concentration and counterion composition when evaluating supplier lots.
