N,N-Dimethyldodecylamine N-oxide (DDAO) is widely used as a surfactant in various cleaning products, including detergents and shampoos, due to its ability to reduce surface tension and enhance the removal of dirt and oils. It is also employed in the formulation of personal care products, such as conditioners and body washes, where it acts as a foaming agent and stabilizer. In industrial applications, DDAO serves as a corrosion inhibitor and emulsifier, particularly in metalworking fluids and oil recovery processes. Additionally, it is utilized in biochemical research as a solubilizing agent for membrane proteins, aiding in their study and analysis. Its mild and non-irritating properties make it suitable for use in sensitive applications, including cosmetics and pharmaceuticals.
