With experience in titration method development, Metrohm offers titrators and sensors well-suited for reliable surfactant content determination.
Surfactant determination is crucial for the quality control of everyday products such as shampoo, detergents, toothpaste, and disinfectants that contain surfactants which facilitate the mixing of generally immiscible substances such as oil and water. Surfactants decrease surface tension and allow the formation of a dispersion between different substances.
Titration of surfactants can be challenging as it involves the consideration of multiple factors. Potentiometric titration, in which, anionic surfactants are titrated with a cationic surfactant and vice versa, is often considered to be the best choice.
