Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- experimental phase 24-25. Feb. 2015
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. No significant deviation was reported. The test substance is adequately characterised, with its isomers composition. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- inspected on November 13 and 14, 2014 / signed on April 08, 2015
- Type of method:
- effusion method: by loss of weight or by trapping vaporisate
- Specific details on test material used for the study:
- - Storage condition of test material: The test item was stored in closed aluminium bottles at 11 - 25 °C, except of two days below 11°C (deepest temperature 10.1°C) C, away from light.
- Temp.:
- 20 °C
- Vapour pressure:
- 0.128 Pa
- Remarks on result:
- other: extrapolated from the measuring range 25-65°C
- Key result
- Temp.:
- 25 °C
- Vapour pressure:
- 0.194 Pa
- Remarks on result:
- other: interpolated from the regression
- Conclusions:
- Low volatility (based on volatility bands criteria for occupational exposure (Chesar / ECETOC TRA), << 500 Pa).
- Executive summary:
The vapour pressure of the test item was determined under GLP following OECD 104/EU A.4 guideline, effusion method (weight loss).
Determinations were conducted at 25, 45 and 65 °C. All temperatures could be evaluated as they showed reproducible weight loss. For these temperatures, 1/T was plotted against log (P). The graph shows a straight line with a correlation coefficient (r) of - 0.9980.
For the test item, the following vapour pressures at 20 °C and at 25 °C were calculated from the regression equation:
Vapour pressure at 20 °C: 0.128 Pa (extrapolated)
Vapour pressure at 25 °C: 0.194 Pa (interpolated, key)

A graph with log P (in Pa) vs. 1/T (in K) was plotted. Since the values were correlated by a linear relation, the data could be fitted by linear regression:
log P = -3177.7 / T + 9.9454
Correlation Coefficient r = -0.9980
Coefficient of Determination r2 = 0.9960
Upon inspection of the cells at the end of the experiment, it was observed that the test item had not changed in appearance.

Description of key information
Low volatility.
No differential volatilisation of isomers in the measuring range.
Key value for chemical safety assessment
- Vapour pressure:
- 0.194 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. The result at 25°C, interpolated from experimental determinations at 25-45-65°C, is retained as key data.
