EC number: 939-457-4
CAS number: 1469983-50-3
Results Assay No. 1
Test item sample weight (ME) 20.0055 g
Reference volume (VA) 79.330 cm3
Temperature during the assay 20.0 °C
Remark: The runs No. 1 and 4 were not taken into account, they were not
complying the quality criteria.
Reuslts Assay No. 2
Test item sample weight (ME) 20.7138 g
Temperature during the assay 20 °C
Remark: The runs No. 2, 3, 5, 6 and 7 were not taken into account, they
were not complying the quality criteria.
The relative density of the test
item (= substance EC 939-455-3) was investigated in a GLP-compliant
study performed in accordance with OECD Guideline 109 (Density of
Liquids and Solids) and EU Method A.3 (Relative Density). The mean
relative density of the test item using the gas comparison method was
1.220 ± 0.003.
As the relative density of the substance EC 939-457-4 has not been
determined experimentally, a read-across approach was followed to fill
in the endpoint. The relative density of a structural analogue substance
(= source substance EC 939-455-3) was investigated in a GLP-compliant
study (Ricau, 2013) performed in accordance with OECD
Guideline 109 (Density of Liquids and Solids) and EU Method A.3
(Relative Density). The mean relative density of the analogue
substance was 1.220 ± 0.003.
By analogy, a mean relative density of 1.220
± 0.003 was reported for the target substance
N-(C12-18(even numbered) acyl) derivs., hydroxides, inner salts (EC
The alkyl C-chain distribution of the source substance EC 939-455-3
significantly overlaps with the one of the target substance EC
939-457-7, the C12-alkyl derivative being the major constituent in both
chemicals. The structural differences in side C-chains is not expected
to lead to significant differences on phys-chem properties.
The relative density of the
structural analogue substance (= source substance EC 939-455-3) was
investigated in a GLP-compliant study (Ricau, 2013) performed in
accordance with standard methods, without deviations. The study is
considered as reliable (Klimisch 1) and was selected as key study for
the endpoint of the target substance EC 939-457-4.
