Widely used as a non-ionic surfactant, it is commonly employed in biological research and industrial applications. In immunoassays such as ELISA, it helps reduce background noise by minimizing non-specific binding on microplate surfaces. It is also added to buffer solutions to enhance the solubility of proteins and stabilize membranes in cell lysis and washing steps. Due to its mild detergent properties, it is suitable for disrupting cells without denaturing proteins. Commonly found in diagnostic kits, it improves assay reproducibility and signal clarity. Additionally, it serves as an emulsifier in pharmaceuticals, cosmetics, and food products, helping to blend water and oil-based ingredients effectively. Its low toxicity and high biocompatibility make it ideal for use in medical and personal care formulations.
