Description

Benzyldimethylnonylammonium Chloride is a quaternary ammonium compound (QAC) widely used as a cationic surfactant and biocide. This versatile chemical is valued for its potent antimicrobial and surface-active properties, making it a critical component in formulations requiring disinfection and material conditioning. It serves key roles in the industrial, institutional, and personal care sectors, where reliable performance and chemical stability are paramount.

Application

• Industrial Biocide & Disinfectant: A key active ingredient in formulations for hard surface disinfectants, algaecides, and sanitizers for industrial water systems and cooling towers.
• Fabric Softener & Textile Auxiliary: Functions as a cationic softener and antistatic agent in laundry rinse cycles and textile manufacturing processes.
• Personal Care & Cosmetics: Used as a preservative and conditioning agent in hair care products (e.g., conditioners) and certain skincare formulations.
• Oilfield & Mining Chemicals: Employed as a corrosion inhibitor, clay stabilizer, and biocide in drilling muds and production fluids.
• Agricultural Adjuvant: Acts as a surfactant and emulsifier in pesticide and herbicide formulations to enhance spreading and adherence.
• Paper & Pulp Industry: Serves as a debonding agent, retention aid, and biocide in paper manufacturing processes.

Quality Control

Our Benzyldimethylnonylammonium Chloride is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, water content, and residue on ignition are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality.
