- Type:
- log Koc
- Value:
- 5.21
- Temp.:
- 35 °C
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- The adsorption coefficient of the test substance was determined to be 1.6 x 105 (log Koc 5.21) at 35 degrees celsius. For four impurities, the adsorption coefficient was determined to be 6.6 x 103 (log Koc 3.82), 1.3 x 104 (log Koc 4.12), 3.7 x 104 (log Koc 4.57) and 9.1 x 104 (log Koc 4.96) at 35 degrees celsius.
- Executive summary:
The adsorption coefficient of the test substance was determined to be 1.6 x 105 (log Koc 5.21) at 35 degrees celsius. For four impurities, the adsorption coefficient was determined to be 6.6 x 103 (log Koc 3.82), 1.3 x 104 (log Koc 4.12), 3.7 x 104 (log Koc 4.57) and 9.1 x 104 (log Koc 4.96) at 35 degrees celsius.
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.
