Description of key information

The available data on the Henry's law constant (0.41, 0.47, 0.68 Pa m³/mol) indicate that 2,6-Xylenol has no real potency to evaporate from the water phase. The value calculated by EUSES (0.275 Pa m³/mol) is in the same range and used for the environmental assessment. 

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
0.4
at the temperature of:
20 °C

Additional information

Values are in the same range and refer to ambient temperatures; 0.4 Pa m³/mol is proposed as the mean value.
