This test method is used to determine the quaternary ammonium salts commonly found in fabric softeners. Quaternary ammonium compounds being the active ingredients in fabric softeners requires... View More

scope:

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 Fig.1 and Fig. 2.

1.3 The analytical procedure appears in the following order:

Section
Apparatus5
Reagents6
Preparation of standard reagents7
Standardization of hyamine solution9
Safety precautions8
Procedure for determination of dialkyl dimethyl quaternaries10
Procedure for determination of diamidoamine based quaternaries11

1.4 This standard does not purport to address all of the safety concerns, if any, 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. See 6.4, 6.6, 6.7 and Section 8 for specific warning statements.
