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

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
