Toxicity to terrestrial plants
Administrative data
- Endpoint:
- toxicity to terrestrial plants: short-term
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because direct and indirect exposure of the soil compartment is unlikely
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
In accordance with REACH Annex IX and X column 2, toxicity testing on terrestrial organisms does not need to be conducted if direct and indirect exposure of the soil compartment is unlikely.
The substance piperazine pyrophosphate (T1063FM) is not supposed to be directly applied to soil.
Furthermore, the substance shows a low adsorptive and bioaccumulative potential (log Kow/Pow < 3) and hence, a relevant distribution into soil and a considerable exposure of soil organisms is not expected.
Low toxicity to microorganisms was observed in a respiration inhibition test (NOEC: 100 mg/L).
Results of aquatic studies indicate that the substance is not very toxic as EC/LC50 is above 42 mg/L for algae, daphnia or fish.
Regarding the biotic degradation of piperazine and pyrophosphate in the environment see the attached “Rationale for data waiving - Piperazine pyrophosphate, biotic degradation”.

Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
