Surfactant Determination by aqueous titration

We encounter surfactants in shampoo, toothpaste, or disinfectants and many more everyday articles. The surfactant content can be determined via titration in aqueous media. This video will show you how to perform such a titration for non-ionic surfactants. Also it will give you important tips, as the determination of the surfactant content can be tricky. 0:00 Intro 0:27 Principle of aqueous surfactant titration 0:49 Calibration factor for non-ionic surfactants 1:06 Example determination of non-ionic surfactants Learn more about the care and handling of the electrodes used in this titration in this video:    • Care and maintenance of aqueous surfactant...   Beside aqeous surfactant titration, you can also determine your surfactant content in a mixture of water and organic solvents.
