Test material
Constituent 1
Study design
- Estimation method (if used):
- QSAR calculation based on Epi-Suite (version 4.1)
- Reference substance:
- not specified
Results and discussion
- Preliminary study:
- The phototrasformation rate was calculated based on QSAR calculations of the OH-rate constant.
K = 0.0000033 (cm3/molecule*day) corresponding to Half-Life = 10 Hrs
Degradation rate constant
- Reaction with:
- OH radicals
- Rate constant:
- 0 cm³ molecule-1 d-1
Applicant's summary and conclusion
- Conclusions:
- The phototrasformation rate was calculated based on QSAR calculations of the OH-rate constant.
K = 0.0000033 (cm3/molecule*day) corresponding to Half-Life = 10 Hrs - Executive summary:
Based on the QSAR calculations, the test substance (L-TEE) is expected to be degraded by phototransformation in air with a half-life of approx. 10 hours.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
