N-Lauryldiethanolamine is widely used in the formulation of personal care and cosmetic products due to its emulsifying and conditioning properties. It helps stabilize mixtures of oil and water, making it a key ingredient in creams, lotions, and hair care products. Additionally, it acts as a surfactant, enhancing the cleansing and foaming abilities of shampoos and body washes. In industrial applications, it serves as a corrosion inhibitor and is utilized in the production of lubricants and metalworking fluids. Its ability to act as a dispersing agent also makes it valuable in the manufacturing of paints and coatings.
