✦ Synopsis

Spinning drop tensiometry has been used in the past to determine low interfacial tension between aqueous surfactant solutions and organic phases that are lighter than water. In this work, we extend the use of the technique to measurement of low interfacial tension between aqueous surfactant solutions and organic phases that are denser than water by altering the wettability of the spinning glass tube. The interfacial tensions of water-SDS-PCE and water-SDS-TCE are determined using this new method. Copyright 1997 Academic Press. Copyright 1997Academic Press

Detergency of oily soil is a complex kinetic process that includes contributions from the wash system physical properties, time and temperature of wash, and the hydrodynamic forces exerted during the wash process.
