Polysorbate 20 is used as emulsifying agent for the preparation of stable oil-inwater emulsions in pharmaceuticals, cosmetics, cleaning compounds. Polysorbate 20 has been used in preextraction of membranes to remove peripheral proteins (used at 2% for extraction of membrane-bound proteins). It has been used as a blocking agent for membrane based immunoassays at a typical concentration of 0.05%. It can be used for lysing mammalian cells at a concentration of 0.05 to 0.5%.


Soluble/miscible in water to give a clear yellow solution; miscible with alcohol, dioxane, and ethyl acetate; practically
