Dodecyltrimethylammonium chloride (DTAC) is widely used as a cationic surfactant in various industrial and research applications. It is commonly employed in the formulation of cleaning products, such as disinfectants and sanitizers, due to its ability to disrupt microbial cell membranes, making it effective against bacteria and fungi. In the textile industry, DTAC is utilized as a softener and antistatic agent, improving the handling and quality of fabrics. It also finds application in the petroleum industry as a corrosion inhibitor and in enhanced oil recovery processes, where it helps reduce surface tension and improve oil displacement. Additionally, DTAC is used in biochemistry and molecular biology as a detergent for solubilizing membrane proteins and in nucleic acid extraction procedures. Its role in nanotechnology includes stabilizing nanoparticles and aiding in the synthesis of nanostructured materials.
