- Key result
- Temp.:
- 20 °C
- Vapour pressure:
- 359 Pa
- Key result
- Temp.:
- 25 °C
- Vapour pressure:
- 486 Pa
- Conclusions:
- The vapor pressure of the test substance has been determined to be 359 Pa at 20 °C and 486 Pa at 25 °C (interpolation).
These values represent the components with the highest vapour pressure. - Executive summary:
The vapour pressure of test item was measured using the static method as described in EU method A.4 and OECD 104. Ten pairs temperature/vapour pressure were used to calculate a regression in a temperature range of 14.7 – 55.9 °C,from which vapour pressure at ambient temperature could be estimated.
From the measured values, the vapour pressure of the test itemwas calculated as 359 Pa at 20 °C and 486 Pa at 25 °C.
These values represent the components with the highest vapour pressure.

The vapour pressure of the test item was measured using the static method as described in EU method A.4. Ten pairs temperature/vapour pressure were used to calculate a regression from which vapour pressure at ambient temperature could be estimated. From the measured values, the vapour pressure of the test item was calculated as 359 Pa at 20.0 °C and 486 Pa at 25 °C. The values of the heating and cooling down phase showed very good correspondence.
Therefore, the result of the study is considered valid.
Description of key information
The vapour pressure of the test item was calculated as 359 Pa at 20 °C and 486 Pa at 25 °C (interpolation).
These values represent the components with the highest vapour pressure.
Key value for chemical safety assessment
- Vapour pressure:
- 486 Pa
- at the temperature of:
- 25 °C
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available.
Therefore, it is considered as a key study, and the result can be retained as key data for purpose of CSA.
Note that the result obtained on this kind of substance should be largely influence by small amounts of volatile constituents and these values don't represent the major part of the substance. Therefore the result should be considered with caution when used for subsequent assessment (worst case).
