Application【应用】
非离子洗涤剂
Caution【警告】
TWEEN 20 may not be stable to autoclaving, particularly with metal cations in buffer solutions. Autoclaving is not recommended without testing for changes in properties. TWEEN 20 is heat sensitive and will darken when exposed to elevated temperatures. Polysorbates have been reported to be incompatible with alkalis, heavy metal salts, phenols, and tannic acid. They may also reduce the activity of many preservatives. Aqueous solutions of polysorbates undergo autoxidation during storage, with changes being catalyzed by light, increased temperature, and copper sulfate.
包装
100, 500 mL in poly bottle
Preparation Note【备注】
TWEEN 20 is miscible in water (100mg/mL), yielding a clear, yellow solution. It is also miscible with alcohol, dioxane, and ethyl acetate. TWEEN 20 is insoluble in liquid paraffin and fixed oils.
