Nonionic detergent. Synonym: Polyethylene glycol sorbitan monolaurate, Polyoxyethylenesorbitan monolaurate
Specific density d20 4: 1.095
Saponification value (KOH mg/g): 40-55
Hydroxyl value (KOH mg/g): 90-110
Appearance: Light-yellow to brown-yellow viscous liquid
TWEEN 20 is a nonionic detergent widely used in biochemical applications.
(1) It is a frequently used member of the polysorbate family. These have been used as emulsifying agents for the preparation of stable oil-inwater emulsions.
(2) It has been used in preextraction of membranes to remove peripheral proteins (used at 2% for extraction of membrane-bound proteins).
(3) It has been used as a blocking agent for membrane based immunoassays at a typical concentration of 0.05%.
(4) It can be used for lysing mammalian cells at a concentration of 0.05 to 0.5%. TWEEN 20 is miscible in water (100 mg/ml), yielding a clear, yellow solution. It is also miscible with alcohol, dioxane, and ethyl acetate; and is practically insoluble in liquid paraffin and fixed oils.
