Standard Test Method for Separation of Active Ingredient from Surfactant and Syndet Compositions
 N D2358

Annotation

This test method covers the procedure for the separation and purification of active ingredient from surfactants and syndet compositions. The separated active ingredient may be used for qualitative examinations. This test method also permits the estimation of total active ingredient level present in the sample under test.

This test method yields the active ingredient together with other alcohol-soluble materials and therefore is useful only in estimating the actual active ingredient level. Correction for the amount of the most common contaminant, sodium chloride, is shown by a separate determination.

The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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. Material Safety Data Sheets are available for reagents and materials. Review them for hazards prior to usage.
