Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Using the HPLC method (OECD 117), the log Pow for the non-aqueous part of the substance was determined to be ≤ 2.05. 

Key value for chemical safety assessment

Additional information

Key value for CSA: log Pow <= 2.05 


Each of the HPLC chromatograms of the substance showed three peaks.  The first two peaks eluted before thiourea (dead time determination). The log Pow  for these peaks was < 0.3. The log Pow  for the third peak was determined to be 2.05.  The  CHARM weighted average log Pow  was calculated to be 1.43 (assuming a log Pow of -5.71 for the two components with log Pow < 0.3).
