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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- read-across based on grouping of substances (category approach)
- Adequacy of study:
- supporting study
- Study period:
- 2008-08-28 to 2008-12-04
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: See Remarks
- Remarks:
- Guideline study, tested with the source substance 68424-31-7 (Tetra-esterification products of C5, C7, C8, C10 fatty acids with pentaerythritol). In accordance to the ECHA guidance document "Practical guide 6: How to report read-across and categories (March 2010)", the reliability was changed from RL1 to RL2 to reflect the fact that this study was conducted on a read-across substance.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
