Description

Dodecyltrimethylammonium is a quaternary ammonium compound (QAC) valued for its potent cationic surfactant properties. This chemical is essential for its ability to modify surfaces, act as a phase-transfer catalyst, and provide antimicrobial activity. It serves as a critical raw material for manufacturers in the pharmaceutical, agrochemical, personal care, and textile industries, where reliable quality and consistent performance are paramount.

Application

• Phase-Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, crucial in organic synthesis for pharmaceuticals and specialty chemicals.
• Antimicrobial Agent: Used in the formulation of disinfectants, sanitizers, and preservatives for industrial and institutional cleaning products.
• Surfactant & Emulsifier: Acts as a cationic surfactant in hair conditioners, fabric softeners, and other personal care formulations.
• Textile Auxiliary: Employed as a softening agent, antistatic agent, and dyeing assistant in textile processing.
• Agrochemical Adjuvant: Enhances the efficacy of pesticides and herbicides by improving wetting, spreading, and adhesion on plant surfaces.
• Analytical Chemistry: Used in ion-pair chromatography and as a modifier in capillary electrophoresis.
• Oilfield Chemicals: Functions as a clay stabilizer and corrosion inhibitor in drilling and production fluids.
• Paper Manufacturing: Serves as a retention aid, drainage aid, and biocide in papermaking processes.

Quality Control

Our Dodecyltrimethylammonium products undergo rigorous quality testing to ensure compliance with industry standards. We provide comprehensive quality assurance, including batch-specific Certificates of Analysis (COA) that detail purity, identity, and impurity profiles. Our quality system is designed to meet the stringent requirements of GMP and ISO 9001 standards, ensuring traceability and consistency for critical applications.

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 bases and incompatible materials such as strong oxidizing agents. This material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent absorption of atmospheric moisture.
