A plot of Log10 (vapour pressure (Pa)) versus reciprocal temperature (1/T(K)) for Run 1 gives the following statistical data using an unweighted least squares treatment.
Slope: -4.32E+03
Standard error in slope: 36.5
Intercept: 14.3
Standard error in intercept: 0.122
The results obtained indicate the following vapour pressure relationship:
Log10(Vp (Pa)) = -4.32E+03 / temp (K) + 14.3
The above yields a vapour pressure (Pa) at 298.15 K with a common logarithm of -0.204.

A plot of Log10 (vapour pressure (Pa)) versus reciprocal temperature (1/T(K)) for Run 8 gives the following statistical data using an unweighted least squares treatment.
Slope: -4.50E+03
Standard error in slope: 53.6
Intercept: 14.9
Standard error in intercept: 0.180
The results obtained indicate the following vapour pressure relationship:
Log10(Vp (Pa)) = -4.50E+03 / temp (K) + 14.9
The above yields a vapour pressure (Pa) at 298.15 K with a common logarithm of -0.187.
Summary of results
The values of vapour pressure at 25°C extrapolated from each graph are summarised in the following table:

The test item did not change in appearance under the conditions used in the determination.
Run 6 was not used as one of the points was over the maximum operating limit meaning the run stopped automatically.
Description of key information
The vapour pressure of Oxyoctaline Formate has been determined to be 0.64 Pa at 25°C, using the vapour pressure balance method, designed to be compatible with Method A4 Vapour Pressure of Commission Regulation (EC) NO 440/2008 of 30 May 2008 and Method 104 of the OECD Guidelines for Testing of Chemicals, 23 March 2006. The vapour pressure of Oxyoctaline Formate has been calculated from the study raw data to be 0.36 Pa at 20°C.
Key value for chemical safety assessment
- Vapour pressure:
- 0.36 Pa
- at the temperature of:
- 20 °C
