Increased temperature can lead to autoxidation of Tween 20 in solution. Autoclaving is not recommended without testing for changes in properties. TWEEN 20 may not be stable to autoclaving, particularly with metal cations in buffer solutions. TWEEN 20 is heat sensitive; it will darken when exposed to elevated temperatures. Autoclaving is done at the customer's risk.
