Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Toxicity to terrestrial plants
Administrative data
Link to relevant study record(s)
- Endpoint:
- toxicity to terrestrial plants: long-term
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- other:
- Justification for type of information:
- The performance of a test for toxicity to terrestrial plants was considered not scientifically justified. REACH Regulation (EC) No 1907/2006, Annex IX, Sect. 9.4, Col. 2, states as follows: “9.4.3: These studies need not to be conducted if direct and indirect exposure of the soil compartment is unlikely.” Direct and indirect exposure of the test item 1,1’-(1,1,2,2-tetramethylethylene)dibenzene to soil is highly unlikely. The test substance is practically insoluble in water. In addition, low exposure is guaranteed, as no sludge application from STP on soil will be done and aerial deposition is negligible. Thus, toxicity to terrestrial plants was considered not scientifically justified.

Description of key information
Direct and indirect exposure of the test item 1,1’-(1,1,2,2-tetramethylethylene)dibenzene to soil is highly unlikely. The test substance is practically insoluble in water. In addition, low exposure is guaranteed, as no sludge application from STP on soil will be done and aerial deposition is negligible. Thus, toxicity to terrestrial plants was considered not scientifically justified.

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.
