Description

Polyethylenimine Branched Permethylated Permethobromide is a quaternary ammonium derivative of branched polyethylenimine, valued for its strong cationic charge density and permanent positive charge. This compound is a critical functional polymer in applications requiring robust binding, flocculation, or antimicrobial activity. It is primarily utilized by industries focused on water treatment, biotechnology, and advanced material synthesis.

Application

• Water Treatment: Acts as a highly effective flocculant and coagulant aid for the removal of suspended solids and organic matter in industrial wastewater.
• Biotechnology & Diagnostics: Used as a nucleic acid binding agent and transfection reagent in molecular biology for DNA/RNA purification and delivery.
• Paper Manufacturing: Serves as a retention aid and drainage promoter in papermaking processes to improve efficiency and product quality.
• Textile Industry: Functions as a dye-fixing agent and antistatic coating to enhance color fastness and fabric performance.
• Antimicrobial Formulations: Incorporated into coatings and disinfectants for its biocidal properties against a broad spectrum of microorganisms.
• Personal Care: Used in hair care and skincare products as a conditioning and film-forming agent.
