- Endpoint:
- partition coefficient
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Justification for type of information:
- ANALOGUE APPROACH JUSTIFICATION
Read-across from sodium cyanate was performed. In aqueous solution cyanate salts dissociate very quickly to cyanate ion and the respective alkali metal ion. It is not expected that Na+ or K+ contribute to the partition coefficient. - Reason / purpose for cross-reference:
- read-across source

Description of key information
No study is available for potassium cyanate. Read across from sodium cyanate was performed instead. In aqueous solution cyanate salts dissociate very quickly to cyanate ion and the respective alkali metal ion. It is not expected that Na+ or K+ contribute to the partition coefficient.
A log Pow of 0.127 was measured (HPLC-Method). This value lies outside the range of the recommended reference items. Therefore, the log Pow of the test item sodium cyanate is stated as < 0.3.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 0.3
- at the temperature of:
- 20 °C
