Description of key information

No study is available for potassium cyanate. Read across from sodium cyanate was performed instead. No differences in auto ignition temperature are expected. The ions K+ and Na+ are not expected to contribute to auto ignition properties of the cyanates. The test item sodium cyanate is considered as not auto-flammable. Thus, also potassium cyanate is considered as not auto-flammable.

Key value for chemical safety assessment

Additional information

The auto-flammability behaviour was determined by placing the test item into a stainless steel cube and heating the environment (laboratory oven with automatic temperature recording) from room temperature to 400 °C. No increase in the temperature of the sample in comparison to that of the oven could be detected, also no signs of ignition could be observed. Therefore, the test item sodium cyanate is considered as not auto-flammable.
