Conclusions:
Interpretation of results (migrated information): very soluble (> 10000 mg/L)
The flask method was chosen for the determination of the water solubility of Sodium toluenesulphonate. The water solubility of the test substance at 20 °C was 818 g/L. The pH of the aqueous samples was 9.2.
Executive summary:

The water solubility of Sodium toluenesulphonate was determined according to OECD Guideline for the Testing of Chemicals No. 105: "Water Solubility", July 27, 1995 and European Community, EC No. 440/2008, Part A: Methods for the Determination of Physico-chemical Properties, Guideline A.6: "Water Solubility", Official Journal of the European Union No. L142, May 31, 2008.

The flask method was chosen for the determination of the water solubility of Sodium toluenesulphonate. The water solubility of the test substance at 20 °C was 818 g/L. The pH of the aqueous samples was 9.2.
