Additional information

Study performed in experimental laboratory (Franke, 2008, RCC) dedicated to estimate water solubility of the test material 3-Mercaptopropionic Acid has been chosen as a key study. Water solubility has been determined to be more than 603.7 g/L by using the simplified flask method. The study followed the procedures indicated by OECD Guideline No. 105 "Water solubility" and EEC Directive 92/69 (Method A.6 "Water solubility"). Based on the high solubility found in the preliminary test a main test as described in the guideline was not performed.

Another study (Rampy, 1973, Dow) qualitatively supports the result obtained in the key study and reports complete solubility of test substance in water.
