Additional information

As result the water solubility was determined to be < 1 mg/L, so that the determination of the surface tension was not necessary according to the guideline OECD 115 (1995) and Council Regulation (EC) No. 440/2008, Method A.5.

Nevertheless the whole family of sulphosuccinates is evaluated and used expressly as a surfactant, therefore surface activity is expected also for the registered substance. The value of two tested similar substances are reported (Nichetti, 2012) and (Butfering, 2013) as 38.9 and 31.6. The substance is then considered a surface active substance.
