Description of key information

Vapour pressure data was available for 7 streams within this Category.  At temperature range of 19-20 °C, vapour pressure ranged from 200 - 2757 Pa,; at temperature of 25 °C vapour pressure was identified as being in the range 111.9- 4100 Pa; at temperature range of ca 34 °C, vapour pressure ranged from 410 - 7900 Pa; at temperatures ca 50 °C, vapour pressure range between 200 - 1230Pa.  One stream had a vapour pressure at 100 °C of <0.02 bar.

Key value for chemical safety assessment
