Key value for chemical safety assessment

Log Kow (Log Pow):
0.3
at the temperature of:
25 °C

Additional information

Partition coefficient was determined by OECD Guideline 117 (Partition Coefficient (n-octanol/water), HPLC Method), using a HPLC with a C18 column. Due to the fact that the retention time of the test substance peaks lay below the retention time of thiourea (log Pow is not calculable), the log Pow of the test substance is stated as < 0.3.

An additional evaluation of the hydrophilicity and lipophilicity of the substance can be done: the solubility in water is high (> 1000 g/L) therefore it can be assumed that the substance is hydrophilic and no lipophilic. Hence this low log Pow can be a realistic value (log Pow <0.3).
