The selected marketed mouthwash formulations was carried out using Traube＊s stalagmometer technique by drop number method to determine their individual surface tension for further identification, structure elucidation and chemical constituents. The formulation I (Potassium nitrate %26 sodium fluoride), formulation II (Chlorhexidine gluconate), formulation III (Thymol, eucalyptol and menthol) were selected for the case study. These formulations were also evaluated to their same quantity mixture ratio with distilled water combination for estimation of different percent composition. The main aim and rationale of the study was to evaluate the surface tension of three selected formulations with distilled water. In individual surface tension study, it was noted that formulation II (48.29 dyne/cm) showed highest value and formulation III (40.81 dyne/cm) showed lowest value comparison between the three formulations under laboratory conditions. The 50% formulation mixture with distilled water showed minimum surface tension (49.20 dyne/cm) and 90% formulation mixture with distilled water showed maximum surface tension (54.30 dyne/cm) amongst other composition. In our present study, all the percent composition values were less than standard surface tension value. The 20% (50.31 dyne/cm), 70% (50.64 dyne/cm), 80% (50.26 dyne/cm) and 30% (49.30 dyne/cm), 50% (49.20 dyne/cm) and also 40% (51.73 dyne/cm), 60% (51.26 dyne/cm) formulation mixture with distilled water showed approximately same surface tension values.
