Polysorbate 60, classified as a hydrophilic nonionic surfactant, serves as a versatile emulsifier, dispersing agent, and solubilizer. It is a niosome. It belongs to the fatty acid esters category of organic compounds. Notably, Polysorbate 60 is predominantly found in the membrane and cytoplasm within the cell. It is characterized by being practically insoluble in water and relatively neutral in its molecular properties.
