Sodium naphthenate is widely used as a corrosion inhibitor in the oil and gas industry, particularly in pipelines and storage tanks, where it helps prevent rust and degradation of metal surfaces. It is also employed as an emulsifier in the production of lubricants and greases, enhancing their stability and performance. In the field of agriculture, it serves as a component in pesticide formulations, improving the adherence and effectiveness of the active ingredients. Additionally, sodium naphthenate is utilized in the manufacturing of synthetic detergents and soaps, where it acts as a surfactant to reduce surface tension and improve cleaning efficiency. Its ability to form stable emulsions makes it valuable in the paint and coating industry, aiding in the dispersion of pigments and additives.
