Experimental Determination of Foaming Characteristics of Aqueous Iso-Propanol Solution by Addition of Surfactants

Abstract

Foams are colloidal systems in which a gas phase is dispersed throughout a continuous liquid phase. The development and stability of aqueous foams have long been of great practical interest because of their widespread occurrence in everyday life. Which parameters influence and govern the aqueous foam development and lead to stable foam formation are critical for soap and detergent manufacturing industries. In the series of experiments conducted, aqueous isopropanol was used as the chief solution where the foaming would be observed. The detergents Surf Excel Blue and Tide were used as surfactants for the foam production. As a result of the tests performed, Foaminess or foam producing capability and foam persistence time were obtained. The results show a distinct correlation between foaming characteristics and concentrations of aqueous isopropanol and surfactants used.
