Acrylamide-acrylamidopropyltrimethylammonium chloride copolymer

Acrylamide-acrylamidopropyltrimethylammonium chloride copolymer (CAS 75150-29-7), also marketed as Praestol 611, is a cationic polyacrylamide used across water treatment and industrial processing. It functions as a flocculant and rheology modifier, enabling efficient separation of suspended solids.

This chemical enables superior viscosity control in aqueous systems. In municipal and industrial water treatment, it destabilizes negatively charged colloidal particles, accelerating sedimentation and improving clarification in effluent and sludge dewatering operations.

Paper manufacturers apply it as a retention and drainage aid, helping fine particles and fillers bind to fiber during sheet formation. This process is essential for maintaining high production speeds and ensuring consistent paper quality across various grades.

In textile and leather processing, it supports wastewater remediation by aggregating dye particles and suspended matter before discharge. This helps facilities meet environmental regulations and reduces the overall chemical load in industrial waste streams.

Personal care formulators incorporate it under the INCI designation Acrylamidopropyltrimonium Chloride/Acrylamide to build viscosity. It is used to improve conditioning performance in both rinse-off and leave-on products for hair and skin care.

This copolymer is supplied as a dry powder or as an aqueous emulsion, with dry forms typically preferred for large-scale water treatment dosing. Molecular weight and charge density vary across grades to match specific application requirements.

Buyers should specify these parameters to ensure optimal performance in their systems. Technical and industrial grades are standard; personal care grades are available with documentation supporting cosmetic compliance for global markets.
