Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to a study was made according Commission Regulation (EC) No. 761/2009 - EC A4 method (2009) and OECD Guideline No. 104 (2006)s, Vapour pressure of ETU is 2.7e-4 Pa at 25°C.
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 25 °C
Additional information
- According to the H&D data base, vapour pressure of ETU (imidazolidine-2-thione) is lower to 1 mm Hg (133.3 Pa) at 20°C
- According to the PPDB database, vapour pressure of ETU (imidazolidine-2-thione) is 13.3 Pa at 25°C. According to « The e-Pesticide Manual », 13th edition, 2004-2005, Version 3.1, The British Crop Protection Council, the vapour pressure of ETU (imidazolidine-2-thione) is 2.7e-4 Pa (25°C)
Three publications gave value for the VP of ETU (imidazolidine-2 -thione)
Due to the imprecision of the vapour pressure data, a study was made according Commission Regulation (EC) No. 761/2009 - EC A4 method (2009) and OECD Guideline No. 104 (2006), the vapour pressure of the test item ETU (imidazolidine-2 -thione, CAS 96 -45 -7) extrapolated at 25 °C is P = 2.7 x 10-4 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).
