Surface active agents. Detergents. Determination of cationic-active matter content - High-molecular-mass cationic-active matter1 Scope This part of ISO 2871 specifies a method for the determination of high molecular mass cationic active materials such as a) quaternary ammonium compounds in which two of the alkyl groups each contain 10 or more carbon atoms, e. g. distearyl dimethyl ammonium chlorides, or b) salts of imidazoline or 3 methylimidazoline in which long chain acylaminoethyl and alkyl groups are substituted in the 1 and 2 positions, respectively. The method is
