Surface Tension is the special property associated with liquid phase of matter. Every liquid try to decrease the surface area to minimize the free surface energy. This leads to increase in stability of liquid drop. The liquid also acts as solvent for the solute. Moreover, some of the solutes are not completely soluble in a proposed solvent. The completely soluble solute in a given solvent is treated as soluble impurity and the incomplete solubility of solute in a solvent is treated as insoluble impurity. In the present work, the effect of soluble and insoluble impurity on the surface tension was studied at room temperature as well as at the washing temperature of solvent. The Jaegers method was utilized to observe the effect of impurities on the surface tension properties. Interestingly, among the different soluble and insoluble solutes (impurities) in water, the magnitude of surface tension of ubtan is observed to be least. This indicates that the spreading ability of ubtans is more and it can be utilized to make the number of applications like in body soap and liquids, for the cosmetic and washing purposes. The observed least value of surface tension to ubtan is may be due to its own ayurvedic composition of sandalwood and turmeric powder with gram flour in milk. The effect on the surface tension values of different solutes signifies their washing ability. The observed change in the values of surface tension may be due to the change in angle of contact due to the added impurities.
