Description

Benzyldodecyldimethylammonium Chloride Dihydrate is a high-purity quaternary ammonium compound (QAC) valued for its potent antimicrobial and surfactant properties. This versatile chemical is essential for formulators requiring a reliable and effective cationic active ingredient. It serves critical functions across diverse industries, including pharmaceuticals, personal care, and industrial water treatment, where its stability and performance are paramount.

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.
• Pharmaceutical & Cosmetic Preservative: Used as a preservative agent in topical creams, ointments, and cosmetic products to prevent microbial spoilage and ensure product safety.
• Algaecide & Biocide for Water Treatment: Effective in controlling algae, slime, and bacterial growth in industrial cooling towers, swimming pools, and recreational water systems.
• Fabric Softener & Textile Auxiliary: Imparts antistatic and softening properties to textiles and is used as a conditioning agent in commercial and household fabric softeners.
• Phase Transfer Catalyst: Facilitates reactions between reactants in immiscible phases in organic synthesis, particularly in the manufacturing of specialty chemicals and pharmaceuticals.
• Oilfield Chemicals: Employed as a biocide and corrosion inhibitor in drilling fluids and production systems to protect infrastructure from microbial-induced corrosion.

Quality Control

Our Benzyldodecyldimethylammonium Chloride Dihydrate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing key parameters such as assay, water content, and residue levels. We support compliance with relevant global regulatory frameworks.

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 after opening to prevent absorption of atmospheric moisture, which can affect quality and handling properties.
