Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Executive summary:

Studies performed on toxicity to fish of pentaerythritol tetranitrate at different concentrations show that the effects caused to fish are not associated to the substance, but to the high pH of the solution (>12) resulting from desensitization, which is much higher than environmental.

To determine the effect of the high pH, resulting from the desensitization process, of test materials, bioassays were performed with Daphnia magna and Pimephales promelas exposed to neutralized versus unneutralized materials.

Description of key information

LC50 values obtained from studies performed on toxicity to fish of pentaerythritol tetranitrate at different concentrations show that the substance is not toxic for fish. Observed mortality seems to be associated to high pH (>12), resulting from the desensitization process.

Key value for chemical safety assessment

Fresh water fish

Fresh water fish
Effect concentration:
