METHOD OF TEST FOR DETERMINATION OF CATIONIC ACTIVE MATTER IN DETERGENTS - BY DIRECT TWO PHASE TITRATION PROCEDURE
This Malaysian Standard describes two methods for the determination of cationic active matter in detergents using the direct two-phase titration procedure. It is applicable to the analysis of cationic active materials such as long-chain quaternary ammonium compounds. (benzyl-dimethyl-stearyl-ammonium chloride. benzyl-dimethyl-dodecyl-ammonium chloride etc.) salts of laurylamine, salts of imidazoline, etc.
Both methods are also applicable to solids or to aqueous solutions of the active material. The molar mass of thecattonic active matter must be known or previously determined if its content is expressed as a percentage by mass.
NOTE. Low molar mass sulphonates of toluene and syiene present as hydrotropes do not interfere when present in concentrations up to 1 5% (rn/rn) on active material. At higher levels, their influence shall be evaluated in each particular Case.
Non-ionic surface active agents. soap, urea and ethylenediaminetetra-acetic acid salts do not interfere.
