Product Description

Physical science defines surface tension as shrinking and minimizing the surface area of a liquid. If the surface is enlarged by the formation of a liquid sheet, it means that the surface/interfacial tension is exerted by a measurable tensile force when the test body (such as a Wilhelmy plate or a Du Nouy ring) is in contact with the liquid. Inside the machine, this force is measured by a high-precision load cell system, so the surface/interfacial tension of the liquid can be calculated.
Surface-active compounds such as surfactants consist of a hydrophilic part and a hydrophobic part, so they preferably adsorb at the interface. They reduce the surface or interfacial tension, respectively, which is crucial for good washing performance or foam stability.There is a limit to the number of surfactant molecules that can be accommodated on a given surface area. The only possibility for "excess" surfactant molecules to protect their hydrophobic moieties from water is to form micelles. The specific surfactant concentration reached to initiate micelle formation is called the "critical micelle concentration" (CMC). This can be easily determined by varying the measurement of surfactant concentration: below the CMC, the surface tension decreases with increasing concentration as more and more surfactant molecules are adsorbed on the surface. Above the CMC basis, further added surfactants are only used to form micelles and the surface tension remains constant.
