Description

Alkyltrimethylammoniumbromide CAS NO 68424-93-1 is a high-purity quaternary ammonium salt (quat) surfactant, widely recognized for its potent cationic properties and excellent surface activity. This compound is a critical raw material for formulators requiring reliable emulsification, antistatic, and antimicrobial performance. It is essential for manufacturers in the personal care, textile, and industrial biocides sectors seeking consistent quality and stable supply chains for their production processes.

Application

• Hair Conditioners & Fabric Softeners: Primary cationic surfactant providing excellent softening, antistatic, and conditioning effects.
• Industrial Biocides & Disinfectants: Active ingredient in formulations for sanitizers, algaecides, and fungicides due to its membrane-disrupting properties.
• Emulsion & Dispersion Stabilizer: Used in polymerization (e.g., styrene, acrylics) and agrochemical formulations to stabilize oil-in-water emulsions.
• Phase Transfer Catalyst: Facilitates reactions between reagents in immiscible solvents in organic synthesis.
• Antistatic Agent: Applied in plastics, textiles, and electronics manufacturing to dissipate static charge.
• Oilfield Chemicals: Component in drilling muds and completion fluids for clay stabilization and corrosion inhibition.

Quality Control

Our Alkyltrimethylammoniumbromide is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, alkyl chain distribution, moisture content, and residue parameters is provided with every 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 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.
