Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Ecotoxicological information

Toxicity to soil macroorganisms except arthropods

Administrative data

toxicity to soil macroorganisms except arthropods: 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:
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”.
