Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
1.91E-04-2.83E-04 Pa at 25 °C (QSAR).
Key value for chemical safety assessment
Additional information
The vapour pressure of the two components of the substance Amides, C18, branched and linear were determined by QSAR calculation with EPIsuite 4.11 (MPBPWIN v1.43) using the Modified Grain Method. Values of 2.83E-04 Pa at 25 °C and 1.91E-04 Pa at 25 °C were determined for the C18 iso and C18 linear components respectively.
In a supporting study the vapour pressures of the two components were also determined by QSAR calculation with SPARC (v4.6). The calculated values of 3.66E-07 Pa at 25 °C for the C18 iso component and 2.94E-07 Pa at 25 °C for the C18 linear component are very low and support the very low vapour pressure values determined by the EPIsuite calculations.
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.
