Polysorbate 20 is nonionic surfactants derived from sorbitan ester, it is soluble or dispersible in water but differ widely in organic and oil solubility.
Polysorbate 20 is typically used as an emulsifying agent for the preparation of stable oil-in-water emulsions, particularly in pharmaceutical applications. It is also used in pre-extraction of membranes to remove peripheral proteins & as a blocking agent on nitrocellulose at a typical concentration of 0.05%.
Series of nonionic surfactants derived from sorbitan esters. They are soluble or dispersible in water but differ widely in organic and oil solubilities. Used as oil-in-water emulsifiers in pharmaceuticals, cosmetics, cleaning compounds, etc.
