Description

Didodecyldimethylammonium Bromide is a high-purity quaternary ammonium salt (quat) widely recognized for its potent cationic surfactant properties. This compound is essential for formulations requiring strong antimicrobial efficacy and surface modification. It is a critical raw material for manufacturers in the pharmaceutical, personal care, and industrial biocides sectors, where reliable performance and consistent quality are paramount.

Application

• As a powerful antimicrobial agent in disinfectant and sanitizer formulations for industrial and institutional use.
• As a cationic surfactant and emulsifier in the production of hair conditioners, fabric softeners, and other personal care products.
• As a phase transfer catalyst in organic synthesis, facilitating reactions between reagents in immiscible phases.
• As a biocide and preservative in coatings, paints, and polymer emulsions to prevent microbial degradation.
• In the formulation of algicides and sanitizers for water treatment applications in cooling towers and swimming pools.
• As a surface modifier and antistatic agent in various industrial processes and material science applications.

Quality Control

Our Didodecyldimethylammonium Bromide is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards and consistent performance specifications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request for full traceability and quality assurance.

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 to prevent absorption of atmospheric moisture, which can affect product quality.
