Description of key information
Additional information
The test item tris(oxiranylmethyl) benzene-1,2,4-tricarboxylate contains no nitrogen, therefore the evaluation of biodegradation has to be based on the ThODNH4.
The mean biodegradation after 28 days of tris(oxiranyl-methyl) benzene-1,2,4-tricarboxylate was 59% (ThODNH4); the 10 day window criterion was not passed.
Whilst tris(oxiranylmethyl) benzene-1,2,4-tricarboxylate cannot be considered to be readily biodegradable under the strict terms and conditions of OECD Guideline No. 301F, the evidence of aerobic degradation (59%) that did not plateau before the end of the 28-day indicate the potential for complete mineralisation in the environment.
In accordance with column 2 of REACh (Regulation (EC) No 1907/2006) Annex X, further biotic degradation testing (required in section 9.2.1) does not need to be conducted based on the findings of the Chemical Safety Assessment; the substance does not fulfil classification criteria according to the applicable regulations and does not fulfil the criteria for vPvB or PBT.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
