Used as a key component in the formulation of industrial lubricants and metalworking fluids, providing excellent emulsifying and dispersing properties. Enhances performance in high-pressure applications by improving stability and reducing wear. Commonly found in rust and corrosion inhibitors due to its ability to form protective layers on metal surfaces. Also serves as a surfactant in specialty cleaning agents and in enhanced oil recovery processes, where it helps reduce interfacial tension between oil and water. Its strong acidic nature makes it effective in catalyst systems for chemical synthesis and refining operations.
