Surface Tension in Water. Surfactant Structure

The surface tensions of Zonyl fluorinated surfactants [48] are shown in Table 4.4. 

When selecting a surfactant to lower the surface tension of an aqueous solution it is useful to know the following  

The concentration needed to lower surface tension to a given value 

The maximum surface tension lowering, or the minimum surface tension achievable at any surfactant concentration 

Note All surfactant concentrations are given in percent solids. Zonyl UR was neutralized with sodium hydroxide to pH 7-8.
