Description

Nonyltrimethylammonium Bromide is a quaternary ammonium salt (quat) surfactant with a long-chain alkyl group, widely recognized for its cationic properties and surface-active capabilities. This compound is valued for its effectiveness as a phase transfer catalyst, antimicrobial agent, and fabric softener component, offering reliable performance in demanding industrial formulations. It serves critical roles in the chemical synthesis, textile treatment, personal care, and water treatment industries, where its cationic nature and surfactant properties are essential.

Application

• Phase Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, particularly in organic synthesis and polymerization processes.
• Antimicrobial/Biocide Agent: Used in disinfectant formulations, algicides, and industrial preservatives due to its cationic surfactant properties.
• Textile Softener and Antistatic Agent: A key ingredient in fabric softeners and conditioners, providing a soft hand feel and reducing static cling.
• Emulsifier and Dispersant: Stabilizes emulsions and aids in the dispersion of pigments and other solids in various chemical systems.
• Surfactant for Personal Care: Employed in hair conditioners and skin care products for its conditioning and emulsifying effects.
• Clay Swelling Inhibitor: Used in drilling mud formulations for oil and gas exploration to control clay hydration.
• Analytical Chemistry Reagent: Serves as an ion-pairing agent in chromatography and other analytical techniques.

Quality Control

Our Nonyltrimethylammonium Bromide 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. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical characteristics is provided with every shipment to guarantee traceability and compliance with your requirements.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
