- Scope
- This standard specifies the two-phase titration method for the determination of anionic surfactants and anionic active substances in detergents. This standard is applicable to the analysis of alkylbenzene sulfonate, alkyl sulfonate, alkyl sulfate, alkyl hydroxy sulfate, alkylphenol sulfate, fatty alcohol methoxy and ethoxy sulfate and dialkyl Solid or liquid products of succinate sulfonates and other anionic actives containing one hydrophilic group per molecule. This standard does not apply to products containing cationic surfactants. If the analysis result is expressed in mass percent, the relative molecular weight of the anionic active substance must be known or determined in advance. Note: ① When the content of low relative molecular weight sulfonate (toluene and xylene sulfonate) as water co-solvent in the detergent is less than 15% of the anionic active substance, it will not interfere with the analysis results, but when it is higher than 15% , and its impact should be estimated. ② Soap, urea, edetate and sodium carboxymethylcellulose do not interfere. ③When there are non-ionic surfactants, the impact should be estimated according to each special situation. ④ Typical inorganic components in detergent formulations, such as sodium chloride, sodium sulfate, sodium borate, tripolyphosphate, sodium perborate, sodium silicate, etc. do not interfere, but bleaching agents other than sodium perborate should be to be destroyed, and the sample should be completely soluble in water.
