Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 estimated QSARs data on environmental degradation of tributyl phosphate are summarized below. Overall, the QSAR estimated data suggest that this substance will degrade fast in the environment.
Degradation rate in water: |
Abiotic transformation: Hydrolysis DT50:
pH5 =11.47 years pH6 =11.47 years pH7 =11.45 years pH8 =11.29 years pH9 =9.865 years pH10 =4.366 years
Biotic transformation: DT50=8.67 days (208.1 hours) |
Degradation rate in sediment: |
DT50=78 days (1873 hours) |
Degradation rate in soil: |
DT50=17.34 days (416.2 hours) |
Degradation rate in air: |
DT50=0.14 days (3.257 hours) DT50 (for reaction with hydroxyl radicals)=1.628 hours |
Based on the data summarized in this section of CSR, tributyl phosphate is considered to degrade rapidly in the environment via abiotic or biotic degradation paths.
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.
