Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The logKoc value of ITC 288/S was determined to be < 1.77 (Koc < 58.9)
Key value for chemical safety assessment
- Koc at 20 °C:
- 58.9
Additional information
One key study is available in which the soil adsorption coefficient of ITC 288/S has been determined according to a method equivalent to the EU method C.19 of the Commission directive 92/69/EEC and the GLP. The determination has been performed by the HPLC method. Under the conditions of the test, the test material showed negligible retention on the HPLC column. The logKoc of the sample was deduced by direct comparison of the sample retention time that of a standard having the low logKoc value (i.e. Simazine, logKoc = 1.77). Therefore, the logKoc value of ITC 288/S was determined to be < 1.77 (Koc < 58.9). Based on this result, ITC 288 has a low potential of adsorption onto soil.
It should be noted that the retention time of the test substance was shorter than the dead time. Therefore, the conditions of the HPLC was maybe not appropriate to this substance. But similar result is estimated by the PCKOCWIN model (v.1.66), confirming the low potential for adsorption onto soil and sediment. Therefore, this study is considered as reliable with restrictions.
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.
