D5070-90(2005) Standard Test Method for Synthetic Quaternary Ammonium Salts in Fabric Softeners by Potentiometric Titrations
Published By | Publication Date | Number of Pages |
ASTM | 2005 | 5 |
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:
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.
