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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Distribution modelling
Administrative data
- Endpoint:
- distribution modelling
- Type of information:
- calculation (if not (Q)SAR)
- Remarks:
- Estimated by calculation
- Adequacy of study:
- supporting study
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Preferred values for this SIDS endpoint. Derived using calculation method software. Current versions of EPIWIN, developed by Syracuse Research Corporation, have not been validated for estimating endpoints for chemicals that contain metals in their molecular structure; therefore, the estimated values derived from the EPIWIN models should be used with caution.

Results and discussion
Percent distribution in media
- Air (%):
- 0.66
- Water (%):
- 18.9
- Soil (%):
- 75.2
- Sediment (%):
- 5.25
Any other information on results incl. tables
Air: half life = 13.3 hr, emissions = 1000 kg/hr
Water: half life = 360 hr, emissions = 1000 kg/hr
Soil: half life = 720 hr, emissions = 1000 kg/hr
Sediment: half life = 3240 hr, emissions = 0 kg/hr
Overall Persistence time = 587 hr
Applicant's summary and conclusion
- Conclusions:
- Based on Level III distribution modeling it is estimated that the majority of DMT[EHTG] released to the environment will partition into soil (75.2%) and water (18.9 %), with a smaller amount in sediment (5.25%).
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.
