Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Dose descriptor:
Effect conc.:
>= 4.5 mg/L
Nominal / measured:
meas. (geom. mean)

test mat. (dissolved fraction)
Basis for effect:

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.
