Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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 soil macroorganisms was considered not scientifically justified.

Key value for chemical safety assessment

Additional information

The performance of a test for toxicity to soil macroorganisms was considered not scientifically justified.  

REACH Regulation (EC) No 1907/2006, Annex IX, Sect. 9.4, Col. 2, states as follows:  

“9.4.1: 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 arthropods was considered scientifically not justified.
