Description of key information
Due to issues with developing a method of quantitation for the test substance that was compatible with the expected matrices, the vapour pressure of HiMo LAB was estimated by two quantitative structure activity relationship (QSAR) methods. The results of these estimations were 2.2E-06 Pa from EPI Suite and 6.48E-09 Pa from SPARC.
Key value for chemical safety assessment
Additional information
The purpose of this study was to determine the vapor pressure of the test substance in at 25ºC using the gas saturation method. Due to issues with developing a method of quantitation for the test substance that was compatible with the expected matrices and a sufficient detection limit, the vapor pressure was estimated by using quantitative structure-activity relationship (QSAR) methods. It was not possible to determine the vapor pressure experimentally. The study was conducted as described in the Huntsman study report, 2013 which was based on OECD method 104. The vapor pressure estimates from the two QSAR methods conducted were as follows. EPI Suite estimated the vapor pressure as 2.2E-06 Pa, SPARC estimated the vapor pressure as 6.48E-09 Pa .
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.
