- Executive summary:
The relative density of Sodium dicyclohexyl 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 1.269 which corresponds to 1.269 g/cm ³.
The results of this test are considered to be relevant and reliable for the assessment.

Additional information
The relative density of Sodium dicyclohexyl 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 1.269 which corresponds to 1.269 g/cm ³.
The results of this test are considered to be relevant and reliable for the assessment.
In the Cytec non-GLP Klimisch 2 study from Rivera (2011) the density of the test substance was measured according to OECD 109 using a pycnometer at room temperature. The study was considered to have a Klimisch 2 score since only limited experimental details were provided. A 10 mL sample cell was used and each test substance specimen was measured 5 times. No significant difference in testing duplicate specimens was detected. A sample weight loss of less than 0.1 wt.% was observed for both specimens. The mean density from both measurements resulted in a density of 1.349 g/cm³. The result is considered as supporting information since the report from Frischmann (2012) provides more study details.
A relative density of 1.269 will be used for the assessment.
