EC number: 944-989-5
CAS number: 2156592-46-8
The source substance Tri (hexyl, octyl, decyl) is not toxic in the range of water solubility. Based on Read-across (please see Analogue Approach) it is expected that the same is valid for 1,2,3-Propanetricarboxylic acid, 2-hydroxy-, tris(C12-13-branched-alkyl) ester, target substance 1.
Due to low water solubility limit of the
test substance a filtrate of a supersaturated stock suspension of
nominal 100 mg/L was tested. Thus no concentrations above the solubility
limit of the test substance in the used test water were tested. Due to
the low water solubility limit no analytical dose verification could be
done in the present test. Therefore, the biological results could not be
related to a specific concentration but to the solubility limit of Tri
(hexyl, octyl, decyl) citrate in the test medium.
In the control and in the undiluted filtrate
of the supersaturated stock suspension all fishes survived until the end
of the test and no signs of intoxication were observed. Therefore, the
96-hour NOEC and the 96-hour LC0 of Tri (hexyl, octyl, decyl) citrate to
Zebra fish were determined to be at least up to the solubility limit.
The NOEC and the LC0 might even be higher, but concentrations in excess
of the solubility limit had not been tested. The 96-hour LOEC, the
96-hour LC50 and the 96-hour LC100 were clearly higher than the
solubility limit of the test substance in the used test water.
