Surface active agents. Detergents. Determination of cationic-active matter content - Cationic-active matter of low molecular mass (between 200 and 500) Ingestion-build-207047 The terahertz method has been1 Scope This part of ISO 2871 specifies a method for the determination of low molecular mass cationic active materials such as monoamines, amine oxides, quaternary ammonium compounds and alkylpyridinium salts which have a main chain of 10 to 22 carbon atoms and not more than 6 other carbon atoms in the cation. The method is also suitable for other cationic active materials. The method is applicable to solids or to aqueous solutions of the active
