Description

Tetradecyldimethylbenzylammonium Chloride is a high-purity quaternary ammonium compound (QAC) widely recognized for its potent antimicrobial and surfactant properties. This versatile chemical is essential for formulators requiring reliable biocidal activity and cationic surface modification. Key industries that depend on this compound include disinfectant manufacturing, water treatment, personal care products, and textile processing.

Application

• Disinfectant & Sanitizer Formulations: A key active ingredient in hospital-grade disinfectants, surface cleaners, and food-contact sanitizers due to its broad-spectrum efficacy against bacteria, fungi, and viruses.
• Water Treatment: Used as an algicide and biocide in industrial cooling towers, swimming pools, and process water systems to control microbial growth and biofouling.
• Personal Care & Cosmetics: Functions as a preservative and conditioning agent in products like shampoos, creams, and lotions to extend shelf-life and improve texture.
• Textile & Leather Processing: Serves as a softener, antistatic agent, and dye-fixing auxiliary, enhancing fabric handle and color fastness.
• Oilfield & Industrial Biocides: Applied in drilling muds, fracturing fluids, and metalworking fluids to prevent microbial-induced corrosion and spoilage.
• Agricultural Adjuvants: Used as a surfactant and emulsifier in pesticide and herbicide formulations to improve spray coverage and adhesion on plant surfaces.

Quality Control

Our Tetradecyldimethylbenzylammonium 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, moisture content, and microbiological efficacy are available upon request to support your quality assurance and regulatory compliance needs.

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 product is hygroscopic (moisture-sensitive); ensure containers are kept sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
