- Executive summary:
In a GLP study conducted according to EU Method A.4, the vapour pressure of Propyl (S)-lactate was determined by using the static method. The vapour pressure was determined to be 40.9 Pa at 20 °C.
Reference
In total 44 measurements were taken at three temperatures. Mesurements 1-6 were discarded due to instable results (propably removal of volatile impurities).
Description of key information

Additional information
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.
