Description of key information

The adsorption / desorption of the cyanuric chloride was estimated by calculation of the log Koc with EPIWIN software using KOCWIN. A log Koc value of 1.902  was calculated.

Key value for chemical safety assessment

Koc at 20 °C:
79.8

Additional information

In accordance with Column 2 adaptation statement of REACH Annex VIII and IX, adsorption/desorption screening and further studies on adsorption/desorption, information requirements 9.3.1 and 9.3.3, may be omitted since the log Kow value for the test substance is <3.0 (CSR sections 1.3 and 4.2.1) and has low potential for adsorption. The log Kow for cyanuric chloride was calculated with the ACD/Log D Suite program to be 2.14. The log Koc value was calculated to be 1.902 based up on the log Kow using KOCWIN.

- In a supporting study (2012-0184-DKB) using a QSAR method a log Koc of 2.54 (at 25 °C) was calculated.

In the supporting study (2012-0400-DKB) the log Koc of 1,3,5-triazinane-2,4,6-trione (CAS no.: 108-80 -5) was estimated to be 0.74 using a QSAR method.

- In the supporting study (2012 -0402 -DKB) the log Koc of 2,4,6-trichloro-1,3,5-triazine (CAS no.:108-77-0) was estimated to be 5.4 using a QSAR method.

Cyanuric chloride hydrolysed rapidly in water. Thus the test item can be considered that it is unlikely to have potential for adsorption / desorption.
