Didecyldimethylammonium Chloride

Product Overview

Didecyldimethylammonium chloride, commonly referred to as DDAC, is a high-performance quaternary ammonium compound renowned for its exceptional biocidal and surfactant capabilities. As a cationic surfactant, this chemical exhibits potent antimicrobial activity against a wide range of microorganisms, including bacteria, fungi, and algae. Our premium grade material is manufactured under strict quality control standards to ensure consistent active content and reliability for demanding industrial processes.

Unlike traditional disinfectants, this compound offers enhanced stability and efficacy even in hard water conditions. It serves as a superior alternative to conventional benzalkonium chloride variants, providing longer-lasting protection and reduced resistance development in microbial populations. This makes it an indispensable component for formulators seeking robust preservation and sterilization solutions.

Key Specifications

Industrial Applications

The versatility of Didecyldimethylammonium chloride allows it to serve critical roles across multiple sectors. In industrial water treatment, it functions as an effective algicide and slimicide, preventing biofouling in cooling towers and circulating water systems. Its corrosion inhibition properties further protect infrastructure integrity.

• Oil Field Operations: Widely utilized for drilling fluids and secondary re-injection water sterilization to prevent reservoir souring.
• Hygiene and Sanitation: Employed in pharmaceutical facilities and public health sectors for surface disinfection and instrument sterilization.
• Textile and Processing: Acts as a softener, emulsifier, and antistatic agent during fabric production and chemical processing.
• Swimming Pools: Provides sustained algae control and water clarification without excessive foaming.

Storage and Handling

To maintain optimal quality, this product should be stored in a dry, ventilated warehouse away from direct sunlight and heat sources. Containers must remain sealed to prevent moisture absorption, as the material is hygroscopic. Safety protocols dictate keeping this chemical separate from anionic surfactants, dyes, or incompatible auxiliaries to avoid precipitation or loss of efficacy. Proper personal protective equipment is recommended during handling to ensure workplace safety.
