Didecyl Dimethyl Ammonium Chloride (DDAC), identified by its CAS number 7173-51-5, is a prominent quaternary ammonium compound (QAC) that offers a unique combination of properties making it highly valuable across various industrial sectors. As a chemical compound used extensively as a biocide, disinfectant, and surfactant, understanding its core characteristics is vital for formulators and procurement specialists alike. If you are looking to buy chemical intermediates, DDAC is a compound worth serious consideration.

Chemically, DDAC is characterized by its twin-chain structure, featuring two decyl chains attached to a dimethyl ammonium cation, balanced by a chloride anion. This structure imparts amphiphilic properties, meaning it has both hydrophilic (water-loving) and hydrophobic (water-repelling) parts. This allows DDAC to act as a surfactant, reducing surface tension and enabling it to emulsify oils and interact with cell membranes.

Its most celebrated attribute is its broad-spectrum antimicrobial efficacy. DDAC effectively disrupts the lipid bilayers of microbial cell membranes, leading to leakage of cellular contents and inactivation or death of the organism. This mechanism makes it potent against bacteria (both Gram-positive and Gram-negative), fungi, enveloped viruses, and algae. Its stability in solution across a pH range of 2 to 10 further enhances its versatility, allowing its use in a wide array of formulations.

The industrial applications of DDAC are extensive and varied. It serves as a key active ingredient in disinfectants and sanitizers used in hospitals, food processing plants, and household cleaning products. In the realm of water treatment, it is critical for controlling microbial growth and preventing fouling in cooling towers, industrial water systems, and swimming pools. DDAC also finds use as a preservative in various formulations, extending the shelf life of products by preventing microbial spoilage.

Furthermore, its applications extend to the textile and paper industries, where it can impart antimicrobial properties and act as an antistatic agent. In agriculture, it can be used for disinfecting equipment and animal housing. For procurement managers seeking reliable chemical suppliers, partnering with a manufacturer that provides high-purity DDAC, often at an 80% concentration, is crucial. Competitive pricing and consistent quality are hallmarks of a good supplier.
