Description

Quaternary Ammonium Compounds, Benzyl-C16-18-Alkyldimethyl, Chlorides are a versatile class of cationic surfactants widely used for their potent antimicrobial and surface-modifying properties. This compound is valued for its excellent biocidal efficacy against a broad spectrum of bacteria, fungi, and viruses, making it a cornerstone in formulation chemistry. It is essential for manufacturers in the disinfectant, personal care, textile, and water treatment industries seeking reliable and effective active ingredients.

Application

• Disinfectant & Sanitizer Formulations: A key active ingredient in hospital-grade disinfectants, surface cleaners, and hand sanitizers for its broad-spectrum antimicrobial action.
• Personal Care & Cosmetics: Used as a preservative and conditioning agent in products like shampoos, creams, and lotions.
• Textile & Fabric Softeners: Imparts antistatic and softening properties to fabrics and is used in commercial and household fabric softeners.
• Industrial Biocides & Algaecides: Employed in cooling water systems, pulp and paper processing, and oilfield applications to control microbial growth.
• Water Treatment: Acts as a flocculant and biocide in municipal and industrial water purification processes.
• Agriculture: Used as a disinfectant for agricultural equipment and in certain pesticide formulations.

Quality Control

Our Quaternary Ammonium Compounds are manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for active matter content, impurity profiles, and performance characteristics. Certificates of Analysis (COA) documenting purity, assay, and other critical parameters are available for every shipment to ensure full traceability and compliance with your formulation 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). Keep away from strong oxidizing agents. This material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent absorption of atmospheric moisture.
