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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Title:
- European Union Risk Assessment Report TRIS(2-CHLORO-1-METHYLETHYL) PHOSPHATE (TCPP)
- Author:
- European Commission Joint Research Centre
- Year:
- 2 008
- Bibliographic source:
- In: RISK ASSESSMENT of May 2008
Materials and methods
- Model:
- calculation according to Mackay, Level I
- Calculation programme:
- The 1997 EQC model, at Level I
- Media:
- air - biota - sediment(s) - soil - water
Test material
- Reference substance name:
- Tris(2-chloro-1-methylethyl) phosphate
- EC Number:
- 237-158-7
- EC Name:
- Tris(2-chloro-1-methylethyl) phosphate
- Cas Number:
- 13674-84-5
- Molecular formula:
- C9H18Cl3O4P

Constituent 1
Study design
- Test substance input data:
- The physicochemical properties entered were as given in section 4; Koc is estimated by the program from Kow as 196, which is sufficiently close to the value of 174 used in the assessment that no adjustment is required to the value of Koc.
- Environmental properties:
- The reaction half-lives have been set at negligible reaction in all compartments. For purposes of examining the importance of the value of Kow and Koc, the emissions were to air, water and soil.
Results and discussion
Percent distribution in media
- Air (%):
- 0
- Water (%):
- 69.8
- Soil (%):
- 29.6
- Sediment (%):
- 0.66
- Other distribution results:
- The results for EQC level I (the simplest model) indicate that water, soil and sediment are all significant should TCPP be stable in the environment. Furthermore, the outputs of the model are sensitive to the Kow (i.e. Koc) input.
Applicant's summary and conclusion
- Conclusions:
- This data comes from the EURAR and fulfilled each validity criterion.
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.
