The vapour pressure at 20 ºC and 25 °C was calculated on the basis of equation log (P) = f (1/t) = a-b/(t+273.15) where P – vapour pressure [hPa], t – temperature [°C].
MPBPVP predicted that the substance has a VP of 1.99E-024 Pa.
MPBPVP predicted that the substance has a VP of 1.13E-009 Pa.
MPBPVP predicted that the substance has a VP of 0.000433 Pa.
MPBPVP predicted that the substance has a VP of 1.53E-013 Pa.
MPBPVP predicted that the substance has a VP of 6.04E-018 Pa.
Description of key information
Weight of evidence: Test method OECD 104. GLP study. The vapour pressure of the aqueous solution of the test item was determined to be 21.10 hPa at 20 ºC and 28.92 hPa at 25 ºC. Since the vapour pressure was measured for the aqueous solution, this result is overestimated.
Weight of evidence: Vapour pressure has been calculated by EPI-Suite, EPA (USA), MPBPVP v1.43 for the main constituents. The estimated vapour pressure for the substance has been determined to be 0.000433 Pa at 25ºC (highest calculated value as the worst case scenario).
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 25 °C
Additional information
Weight of evidence: Determination of vapour pressure of the test substance was performed according to OECD 104 Guideline and EU A.4 Method, using the static method. The vapour pressure of test substance was calculated at 20 ºC and 25 ºC and was determined to be 21.10 hPa and 28.82 hPa respectively.
According to Handbook of Chemistry and Physics: 73rd Edition (1992 -93), the vapour pressure of water at 20 and 25 ºC is 2.33880 and 3.16900 kPa respectively, which are equivalent to 23.3880 and 31.6900 hPa. Taking into account that the determination of the vapour pressure was performed with the test substance in aqueous solution, it could be concluded that the vapour pressure measured is related to the water content.
Weight of evidence: Vapour pressure of the main constituents has been calculated by EPI-Suite, EPA (USA), MPBPVP v1.43:
2-[3-(2{3-[4,5-dihydroxy-1,3-dioxolan-2-yl)(hydroxy)methyl]-4,5-dihydroxy-2-oxoimidazolidin-1-yl}-1,2-dihydroxyethyl)-4,5-dihydroxy-2-oxoimidazolidin-1-yl]-2-hydroxyacetaldehyde: The estimated vapour pressure at 25 ºC is 1.99E-024 Pa (EPI-Suite, MPBPVP v1.43).
2-[4,5-dihydroxy-3-(1-hydroxy-2-oxoethyl)-2-oxoimidazolidin-1-yl]-2-hydroxyacetaldehyde: The estimated vapour pressure at 25 ºC is 1.13E-009 Pa (EPI-Suite, MPBPVP v1.43).
4,5-dihydroxyimidazolidin-2-one: The estimated vapour pressure at 25 ºC is 0.000433 Pa (EPI-Suite, MPBPVP v1.43).
(2S)-2-[(4S,5S)-3-[(S)-[(4R,5R)-4,5-dihydroxy-1,3-dioxolan-2-yl](hydroxy)methyl]-4,5-dihydroxy-2-oxoimidazolidin-1-yl]-2-hydroxyacetaldehyde: The estimated vapour pressure at 25 ºC is 1.53E-013 Pa (EPI-Suite, MPBPVP v1.43).
1-{2-[4,5-dihydroxy-3-(1-hydroxy-2-oxoehtyl)-2-oxoimidazolidin-1-yl]-1,2-dihydroxyethyl}-3-(1,2-dihydroxyethyl)urea: The estimated vapour pressure at 25 ºC is 6.04E-018 Pa (EPI-Suite, MPBPVP v1.43).
