Description

Dialkyl(C12-C18) Methyl Benzyl Ammonium Chloride is a high-purity quaternary ammonium compound (quat) widely recognized for its potent antimicrobial and surfactant properties. This versatile chemical is essential for formulating effective disinfectants, sanitizers, and industrial biocides that require broad-spectrum efficacy and stability. It is a critical raw material for manufacturers in the hygiene, institutional cleaning, water treatment, and oilfield chemical sectors seeking reliable, high-performance active ingredients.

Application

• Disinfectant & Sanitizer Formulations: Primary active ingredient in hospital-grade disinfectants, surface cleaners, and food-contact sanitizers.
• Algaecides & Biocides: Used in industrial water treatment systems, cooling towers, and recreational water to control algae, bacteria, and slime.
• Oilfield Chemicals: Acts as a biocide and corrosion inhibitor in drilling fluids, fracturing fluids, and produced water treatment.
• Textile & Leather Processing: Serves as a softening agent, antistatic agent, and disinfectant in finishing baths.
• Agricultural Adjuvants: Used as a surfactant and emulsifier in pesticide and herbicide formulations to enhance efficacy.
• Personal Care Products: Found in conditioners and hair care products as an antistatic and conditioning agent (subject to concentration and regulatory approval).

Quality Control

Our Dialkyl(C12-C18) Methyl Benzyl Ammonium Chloride is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by titration and identification by FTIR, to ensure it meets precise specifications for active content, pH, and clarity. Certificates of Analysis (COA) documenting full compliance are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents. The product is hygroscopic (moisture-sensitive); ensure containers are properly sealed after use to prevent moisture absorption.
