Surfactant Determination by two-phase titration

We encounter surfactants in shampoo, toothpaste, or disinfectants and many more everyday articles. The surfactant content can be determined via titration in a mixture of water and organic solvents. Traditionally, chlorinated solvents are used as organic solvents. Modern two-phase titration of surfactants uses non-chlorinated solvents. This video will show you how to perform a two-phase surfactant titration and give important tips, as the determination of the surfactant content can be tricky. 0:00 Intro 0:23 Principle of two-phase surfactant titration 0:51 Anionic surfactant titration for a shampoo 1:19 pH adjustment of the sample 2:00 Tips for the titration Learn more about the care and handling of the electrodes used in this titration in this video:    • Care and maintenance of two-phase surfacta...   Beside two-phase surfactant titration, you can also determine your surfactant content in aqueous media without organic solvents.
