Used primarily as a cationic surfactant in various industrial and personal care applications. It is effective in hair conditioners and fabric softeners due to its ability to reduce static and improve texture. In the pharmaceutical industry, it serves as an antimicrobial agent, helping to inhibit the growth of bacteria and fungi. Additionally, it is utilized in research as a stabilizing agent for proteins and nucleic acids, enhancing their solubility and stability in biochemical assays. Its surfactant properties also make it valuable in the formulation of cleaning products, where it aids in emulsifying oils and dirt for easier removal.
