Didecyl Dimethyl Ammonium Chloride (DDAC) is a chemical compound that has carved out a significant niche across various industries due to its potent antimicrobial and surfactant properties. As a leading DDAC manufacturer and supplier based in China, we understand the importance of providing clear, accurate information about our products. This article aims to demystify DDAC by exploring its key chemical properties and detailing its diverse application landscape.

At its core, DDAC is a quaternary ammonium compound (QAC) and a cationic surfactant. Its chemical formula is C22H48N·Cl, with CAS Number 7173-51-5. The 'didecyl' designation refers to the presence of two ten-carbon alkyl chains attached to the nitrogen atom, which contribute significantly to its hydrophobic properties and its ability to disrupt microbial cell membranes. The positive charge on the nitrogen atom, characteristic of QACs, allows it to interact strongly with negatively charged surfaces, including those of bacteria and viruses, leading to cell lysis and death. This unique structure underpins its broad-spectrum biocidal activity.

Chemically, DDAC is typically observed as a light yellow transparent liquid or paste at room temperature. It exhibits excellent solubility in water and various organic solvents like ethanol, making it amenable to a wide range of formulation types. Its chemical properties also include stability under normal storage conditions and low irritation potential, which are critical factors for its use in both industrial and consumer product applications. The ability to buy DDAC with consistent quality is paramount for formulators.

The versatility of DDAC is evident in its widespread applications. In industrial settings, it serves as an effective biocide in water treatment systems, controlling algae and bacteria in cooling towers and preventing biofouling. Its efficacy in oilfield operations as an injection water biocide is also noteworthy. Furthermore, DDAC is a recognized wood preservative, offering protection against fungal decay and insect infestation.

In the consumer product sector, DDAC is a key ingredient in disinfectants and sanitizers, widely used in healthcare facilities, food processing plants, and households. Its antimicrobial action makes it ideal for surface cleaning. Moreover, its conditioning properties find application in cosmetic and personal care products, such as hair conditioners and hand sanitizers, where it imparts a smooth feel and preserves product integrity. For businesses looking to purchase DDAC, understanding these applications can guide their procurement decisions.
