Polyquaternium 4

Polyquaternium-4 (CAS 92183-41-0) is a cationic cellulose-derived polymer used as a conditioning and film-forming agent.

Where is Polyquaternium 4 used?

• Hair care: improves wet combability and reduces static in shampoos and conditioners
• Leave-in treatments: enhances manageability
• Skin care: lightweight film former that improves texture without heavy or greasy residue
• Textile processing: surface modifier for softness and antistatic performance
• It also aids in dye retention on natural and synthetic fibers.
• Paper and nonwoven manufacturing: modifies surface charge and improves wet strength or bonding

Good to know: Quaternary ammonium groups along its backbone bind to negatively charged surfaces, giving deposition and retention on hair, skin and fibrous substrates. Buyers should confirm active content, viscosity specification and preservation system.
