Final Result

The solubility of the test item Chlorophene in methanol and in toluene at 10 °C, 20 °C and 30 °C were > 250 g/L (visually checked in preliminary tests). Therefore it was not necessary to determine the exact value of the solubility of the test item in a main test.

Description of key information

Solubility in methanol is > 250 g/L at 10 ºC, 20 ºC, and 30 ºC; solubility in toluene is > 250 g/L at 10 ºC, 20 ºC, 30 ºC (CIPAC MT 157, CIPAC MT 181).

Key value for chemical safety assessment
