1.1 This test method describes a potentiometric titration procedure for the determination of quaternary ammonium salts in fabric softeners. This test method is intended for the analysis of known quaternary ammonium salts such as the dialkyl dimethyl quaternary ammonium compound type and the diamidoamine based quaternary ammonium compound type. 1.2 The quaternary ammonium salts conform to the structures shown in Figs. 1 and 2. 1.3 The analytical procedure appears in the following order: Section Apparatus 5 Reagents 6 Preparation of standard reagents 7 Standardization of hyamine solution 8 Safety precautions 9 Procedure for determination of dialkyl dimethyl quaternaries 10 Procedure for determination of diamidoamine based quaternaries 111.4 This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
