Acrylamide-acrylamidopropyltrimethylammonium chloride copolymer

Acrylamide-acrylamidopropyltrimethylammonium chloride copolymer (CAS 75150-29-7) is a cationic polyacrylamide. Also marketed as Praestol 611.

Where is Acrylamide-acrylamidopropyltrimethylammonium chloride copolymer used?

• Water treatment: flocculant and rheology modifier that separates suspended solids
• Municipal and industrial water treatment: destabilizes negatively charged colloidal particles, accelerating sedimentation and improving clarification in effluent and sludge dewatering
• Paper manufacturing: retention and drainage aid that binds fine particles and fillers to fiber during sheet formation
• Textile and leather processing: aggregates dye particles and suspended matter in wastewater before discharge
• Personal care: builds viscosity under the INCI designation Acrylamidopropyltrimonium Chloride/Acrylamide
• It improves conditioning performance in rinse-off and leave-on hair and skin care products.

Good to know: Molecular weight and charge density vary across grades; buyers should specify these parameters. Technical and industrial grades are standard, while personal care grades come with documentation supporting cosmetic compliance for global markets.
