Adsorption and Aggregation Properties of Some Polysorbates at Different Temperatures
{{output}}
Measurements of the surface tension of aqueous solutions of polysorbates (Tween 20, Tween 60 and Tween 80) at 293, 303 and 313 K were made. On the basis of the obtained results the Gibbs surface excess concentration of the Tweens at the water-air interface and... ...
