Polymethacrylamidopropyltrimethylammonium chloride

Polymethacrylamidopropyltrimethylammonium chloride (CAS 68039-13-4), also marketed as Polymethacrylamidopropyltrimonium chloride, is a cationic polyelectrolyte.

Where is Polymethacrylamidopropyltrimethylammonium chloride used?

• Hair and skin care: conditioning agent and film former
• Shampoos, conditioners and leave-on treatments: improves wet combability and reduces static
• Water treatment: coagulant and flocculant that destabilizes suspended particles and accelerates sedimentation
• Municipal and industrial effluent streams: clarifies water
• Textile dyeing and finishing: improves dye uptake on anionic fibers and enhances color fastness
• Paper manufacturing: retention aid and surface-charge modifier
• Its permanent positive charge density drives substantivity to negatively charged surfaces.

Good to know: Cosmetic grades meet purity requirements for leave-on and rinse-off personal care applications.

Commercial specifications

• Active polymer content typically 30% to 50% depending on grade and supplier specification
• Drums and intermediate bulk containers
