ICUMSA Method GS2/4/8-54 (2017)


Determination of Non-Ionic Surfactants in White Sugar, Molasses and Dried Beet Pulp – Tentative



1 Scope

This method is applicable to measure trace levels of non-ionic surfactants as Bismuth Active Substances (BiAS) in reference to nonylphenol-ethoxylate with 10 ethylene oxide units (NP10).
The presence of anionic surfactants does not interfere with the determination, however, interference of cationic surfactants should be considered.
