Product Description

Dimethyl diethyl ammonium chloride (DMDAC) is a quaternary ammonium salt that is commonly used as a cationic surfactant and a disinfectant in various industrial applications. It is a water-soluble white crystalline solid that has a strong positive charge, making it useful for various applications.

As a cationic surfactant, DMDAC is used in the production of detergents, fabric softeners, and other cleaning products. It can help to improve the cleaning efficiency of these products by reducing the surface tension of water and enhancing the wetting and spreading properties of the solution. DMDAC can also help to reduce static electricity, making it useful in the production of antistatic agents.

DMDAC is also used as a disinfectant and biocide in various industrial applications, such as water treatment, oil and gas production, and pulp and paper manufacturing. It is effective against a wide range of microorganisms, including bacteria, viruses, and fungi, and can help to prevent the growth of biofilms in industrial systems.

While DMDAC is generally considered to be safe and effective, it is important to handle it with care, as it can be irritating to the skin and eyes. Proper safety precautions, such as wearing gloves and goggles, should be taken when handling this compound. In addition, DMDAC should be stored in a cool, dry place away from direct sunlight and incompatible materials.
