Additional information

In the non-GLP Klimisch 1 key study from Frischmann (2012), the water solubility of the test item Butanedioic acid, sulfo-, 4-[2-[(2-hydroxyethyl)amino]ethyl] ester, N-C18-unsatd. acyl derivs., disodium salts was determined according to OECD 105 and EU method A.6. The test item solubility was determined for concentrations up to 213.1 g/L. Higher concentrations were also soluble but formed a gel. The highest water solubility was reported as > 370 g/L.


The results of this study are considered relevant and reliable for the risk assessment.
