Executive summary:

The relative density of Sodium di(1.3-dimethylbutyl) sulfosuccinate was determined by Frischmann (2012) in a Klimisch 1 non-GLP study according to EC A.3 and OECD 109 by using the pycnometer method. The test item has a relative density D420 of 1.159, which corresponds to 1.159 g/cm ³.

The results of this test are considered to be relevant and reliable for the assessment.
