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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 500-116-6 | CAS number: 52609-19-5 1 - 2.5 moles ethoxylated
Vapour pressure
Administrative data
Link to relevant study record(s)
Description of key information
<= 0.00051 hPa at 20 °C (OECD 104, Grain-Watson estimation)
0.00013 hPa at 20 °C (extrapolated from vapour pressure curve (DSC measurements))
Key value for chemical safety assessment
- Vapour pressure:
- 0.001 hPa
- at the temperature of:
- 20 °C
Additional information
The vapour pressure was determined experimentally and estimated by calculation based on the lowest possible boiling temperature (329 °C).
Since the experimental value (0.00013 hPa, extrapolated from vapour pressure curve (DSC measurements)) fell outside the recommended range for DSC measurements, a calculation algorithm as described in OECD 104 (Grain-Watson method) was used.
No information on transition / decomposition is given.
The QSAR calculations with MPBPWIN v1.43 (Episuite) qualitatively support the experimental data for vapour pressure.
The limit vapour pressure 0.00051 hPa at 20 °C is taken as 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.
