Description

Octadecy Trimethyl Ammonium Bromide is a high-purity quaternary ammonium salt widely recognized for its cationic surfactant properties. This compound is essential for its potent antimicrobial and antistatic effects, as well as its ability to modify surface properties in various formulations. It serves as a critical raw material for manufacturers in the personal care, textile, water treatment, and pharmaceutical industries.

Application

• Fabric Softeners & Conditioners: A key cationic agent providing excellent softening, antistatic, and fragrance-retention properties to textiles.
• Hair Conditioners & Cream Rinses: Used to impart manageability, softness, and shine by neutralizing anionic charges on hair fibers.
• Biocides & Disinfectants: Acts as an effective active ingredient in formulations targeting bacteria, algae, and fungi for industrial and institutional cleaning.
• Phase Transfer Catalyst: Facilitates reactions between reactants in immiscible phases in organic synthesis, particularly in pharmaceutical manufacturing.
• Emulsifier & Stabilizer: Aids in the formation and stabilization of oil-in-water emulsions in cosmetic and agrochemical products.
• Antistatic Agent: Applied in plastics and synthetic fibers to reduce static electricity buildup.
• Water Treatment: Used as a flocculant and sludge dewatering aid in certain wastewater treatment processes.
• Analytical Chemistry: Serves as an ion-pairing reagent in chromatographic techniques like HPLC.

Quality Control

Our Octadecy Trimethyl Ammonium Bromide is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and performance. A Certificate of Analysis (COA) documenting results for assay, moisture, residue, and other critical parameters is provided with every shipment to guarantee consistency and traceability.

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.
