The evaluation of various acoustical and thermo dynamical parameters which provide an idea into the nature of molecular interactions in aqueous non-ionic surfactant solutions. The measurement of ultrasonic velocity in aqueous solutions an important tool for the calculation of various acoustical parameters. These parameters have been computed through velocity, density and viscosity measurements of non-ionic surfactants (Saponin, Glucopon and Sorbitan sesquioleate) in aqueous medium. This above work was done for different concentration ranges at three different temperatures 303, 313 and 323K using Ultrasonic interferometer. The Critical Micelle Concentration (CMC) was determined to be 1.0% of Water-Saponin, Water - Glucopon, 0.8% of Water - Sorbitan sesquioleate system. These samples were characterised by UV studies.
