The auto-ignition temperature of
the test item (= substance EC 939-455-3 in aqueous commercial product)
was investigated in a GLP-compliant study performed in accordance with EU
Method A.15 (Auto-Ignition Temperature (Liquids and Gases)). The mean
auto-ignition temperature of the test item was 438 ± 4 °C.
The study was performed on a commercial product (aqueous solution) as thesubstance
EC 939-455-3 is manufactured and used in a liquid form.
The self-ignition temperature of the test
item was determined according to Method A.15 of Commission Regulation
(EC) N°440/2008 of 30 May 2008 and GLP. No deviation of the guidelines
was observed during the test. Before the experimentation, the
accuracy of the apparatus was assessed with a reference
item. Based on the result obtained with the reference item, the
apparatus was considered acceptable for use. The
test is repeated at different temperatures (from about 100 to about 600
°C) with suitable sampling
volumes(70 µL for this study)until
the minimum value of the ignition temperature is observed. The
mean self-ignition temperature of the test item was 438 ± 4 °C
The substance EC 939-457-4 is manufactured and used in a liquid form
(aqueous solutions). The security physico-chemical parameters were
therefore assessed from tests performed on aqueous solutions.
As the auto-ignition temperature of the substance EC 939-457-4 in
aqueous solution have not been determined experimentally, a read-across
approach was followed to fill in the endpoint. The auto-ignition
temperature of a structural analogue substance (= source substance EC
939-455-3) in aqueous solution was investigated in a GLP-compliant study
(Colombies, 2013) performed in accordance with EU Method A.15
(Auto-Ignition Temperature (Liquids and Gases)). The mean auto-ignition
temperature of the analogue substance was 438 ± 4 °C. By analogy, an
auto-ignition temperature of 438 ± 4 °C was reported for the target
numbered) acyl) derivs., hydroxides, inner salts (EC 939-457-4) in
aqueous solution, at a similar concentration range).
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.
temperature of the structural analogue substance (= source
substance EC 939-455-3) in aqueous solution was investigated
in a GLP-compliant study (Colombies, 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 in aqueous solution.
