AB-275 Potentiometric two-phase titration of anionic surfactants in washing powders and liquid washing agents  
Potentiometric two-phase titration of anionic surfactants in washing powders and liquid washing agents

The two-phase titration with potentiometric indication is a universal method for the determination of ionic surfactants in washing agents. The obtained results are comparable to those of the classical two-phase titration according to Epton (mixed indicator system disulfine blue / dimidium bromide). In this Bulletin special attention is paid to various parameters that can affect the potentiometric surfactant titration. The information provided enables the user to precisely determine the content of anionic surfactants in almost any formulation.
