Reason / purpose:
read-across source
Key result
Duration:
21 d
Dose descriptor:
NOEC
Effect conc.:
>= 4.5 mg/L
Nominal / measured:
meas. (geom. mean)
Conc. based on:
test mat. (dissolved fraction)
Basis for effect:
reproduction
Conclusions:
No effects on the reproduction were reported up to the limit of water solubility in this test system.

Description of key information

The analogue substance was not toxic under test conditions in the range of water solubility.

Key value for chemical safety assessment

Additional information

No chronic invertebrate toxicity studies are available for the substance Esterification products of Guerbet alcohols, C24-26, branched and cyclic with benzene-1,2,4-tricarboxylic acid 1,2-anhydride.

For the analogue substance, the highest tested concentration did not exhibit negative effects on the reproduction rate or survival of the parent animals. Hence the NOEC >= 4.5 mg/L (highest concentration under test conditions) and LOEC > 4.5 mg/L (highest concentration under test conditions). The test substance was not toxic under test conditions in the range of water solubility.
