Description

Didecyl Dimethyl Ammonium Chloride is a quaternary ammonium compound (quat) widely recognized for its potent antimicrobial and surfactant properties. This versatile chemical is a critical component in formulating effective disinfectants, sanitizers, and industrial biocides. It is essential for manufacturers in the hygiene, water treatment, agricultural, and industrial cleaning sectors seeking reliable, broad-spectrum antimicrobial activity.

Application

• Disinfectant & Sanitizer Formulations: A key active ingredient in hospital-grade disinfectants, surface sanitizers, and food-contact sanitizers for its efficacy against bacteria, viruses, and fungi.
• Industrial & Institutional Cleaners: Used in cleaners for floors, walls, and equipment in manufacturing plants, schools, and commercial facilities.
• Water Treatment: Acts as a biocide in cooling towers, pulp and paper mills, and oilfield water systems to control algae, slime, and microbial growth.
• Agricultural Applications: Employed as a disinfectant in animal husbandry for barns, equipment, and foot baths to prevent disease spread.
• Algaecide & Fungicide: Effective in controlling algae in swimming pools, ponds, and on building surfaces, and as a wood preservative fungicide.
• Textile & Leather Processing: Serves as a softener, antistatic agent, and biostatic finish for fabrics and leather goods.
• Personal Care Products: Used in low concentrations as a preservative in certain cosmetics and toiletry formulations.
• Oilfield & Fuel Additives: Functions as a biocide in fuel tanks and drilling fluids to prevent microbial contamination and degradation.

Quality Control

Our Didecyl Dimethyl Ammonium Chloride is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, composition, and performance. A Certificate of Analysis (COA) documenting key parameters such as assay, water content, and impurity profile 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, well-ventilated area away from incompatible materials such as strong alkalis and strong oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent moisture absorption.
