Description

2,5-Ionene CAS NO 51325-19-0 is a synthetic cationic polymer belonging to the ionene class, characterized by its quaternary ammonium groups integrated directly into the polymer backbone. This unique structure provides strong, permanent positive charges, making it an exceptionally effective flocculant, retention aid, and antimicrobial agent. It is a critical material for industries requiring advanced water treatment solutions, paper manufacturing, and the development of biocidal formulations.

Application

• Water and Wastewater Treatment: As a highly effective cationic flocculant for the removal of suspended solids, organic matter, and clarification of process water.
• Paper and Pulp Industry: Used as a retention and drainage aid to improve fiber and filler retention on the paper machine wire, enhancing production efficiency and paper quality.
• Biocidal and Antimicrobial Formulations: Incorporated into disinfectants, sanitizers, and preservative systems due to its membrane-disrupting activity against a broad spectrum of microorganisms.
• Textile Processing: Acts as a dye-fixing agent and softener, improving color fastness and fabric hand feel.
• Oilfield Chemicals: Utilized as a clay stabilizer and shale inhibitor in drilling fluids to prevent formation damage.
• Personal Care Products: Functions as a conditioning agent and preservative booster in hair care and skincare formulations.
• Research and Development: Serves as a model cationic polyelectrolyte for studying polymer-surfactant interactions, gene delivery vectors, and antimicrobial surfaces.

Quality Control

Our 2,5-Ionene is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure consistent performance and meets the specifications agreed upon with our customers. A Certificate of Analysis (COA) detailing key parameters such as assay, viscosity, and ionic content is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture, which may affect product performance.
