Description

N,n-Diethylaminoethyl Methacrylate Q-Salt, Methosulfate is a specialized quaternary ammonium salt monomer, also known as a polymerizable cationic surfactant. This compound is valued for its ability to impart a permanent positive charge to polymer chains, enhancing adhesion, dye affinity, and antimicrobial properties in final materials. It is primarily sought by manufacturers in the water treatment, personal care, textile, and specialty coatings industries for developing advanced functional polymers.

Application

• Flocculants & Coagulants: A key monomer for synthesizing cationic polyacrylamides (CPAM) used in municipal and industrial wastewater treatment.
• Hair & Skin Care Products: Used in conditioning polymers for shampoos, conditioners, and creams to improve substantivity and feel.
• Textile Auxiliaries: Imparts cationic sites on fibers for enhanced dye uptake (especially for anionic dyes), color fastness, and antistatic properties.
• Paper Retention Aids: Improves retention of fillers and fines in papermaking processes, increasing yield and water clarity.
• Antimicrobial Coatings: Serves as a building block for polymers with inherent biocidal activity on surfaces.
• Oilfield Chemicals: Component in drilling mud additives and viscosity modifiers.
• Ion Exchange Resins: Used in the synthesis of specialty resins for water softening and purification.

Quality Control

Our N,n-Diethylaminoethyl Methacrylate Q-Salt, Methosulfate is produced under a stringent quality management system. Each batch is analyzed to ensure consistent purity, ionic content, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, moisture content, residual monomer, and identity confirmation is provided with every shipment. We support compliance with relevant global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
