Surface active agents — Detergents — Determination of anionic-active matter by manual or mechanical direct two-Phase titration procedure
Title : BDS ISO 2271:2021
This International Standard specifies a manual or mechanical method for the determination of anionic-active matter present in detergents. The method is applicable to solids or to aqueous solutions of the active material. The relative molecular mass of the anionic active matter has to be known. The method is not applicable if cationic surface active agents are present.
