Description

Didecyldimethylammonium Bromide is a high-purity quaternary ammonium compound (quat) widely recognized for its potent antimicrobial and surfactant properties. This compound is essential for formulators requiring a reliable and effective active ingredient for disinfectant and sanitizer applications. Key industries that depend on this material include industrial biocides, institutional cleaning, water treatment, and personal care, where its broad-spectrum efficacy and formulation stability are critical.

Application

• Broad-Spectrum Disinfectants & Sanitizers: A key active ingredient in formulations for hard surface disinfectants, hospital-grade cleaners, and food contact surface sanitizers.
• Algaecides & Biocides for Water Treatment: Used in cooling towers, swimming pools, and industrial water systems to control algae, bacteria, and slime formation.
• Industrial Process Preservation: Acts as a preservative and antimicrobial agent in metalworking fluids, pulp and paper processing, and oilfield operations.
• Textile & Leather Treatment: Imparts antimicrobial properties to fabrics, leather goods, and technical textiles for odor control and material preservation.
• Personal Care & Cosmetics: Employed as a preservative and conditioning agent in select rinse-off formulations, subject to regional regulatory compliance.
• Agricultural Adjuvants: Functions as a surfactant and dispersant in pesticide and herbicide formulations to enhance efficacy and coverage.

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); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality.
