Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The biodegradation of the substance was investigated in a modified MITI test corresponding to OECD 301C . The degree of biodegradation by BOD is reported to be 0% (CITI, 1992). The substance triethyl phosphate cannot be considered readily biodegradable.
The biodegradation of the substance was investigated in a Zahn-Wellens test (OECD 302C). 98% biodegradation of the test substance was seen in 21 days under the conditions of this study (Kanne, 1987). However the criterion for inherent biodegradability was not reached as after 7 days only 18% biodegradation were observed.
QSARs for ultimate and ready biodegradation using Biowin 3 and 6 show that the substance is not readily biodegradable. Ultimated biodegradation may be reached within weeks.
In a weight of evidence approach of these three studies it is concluded that Triethyl phosphate is not biodegradable.
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.
