Calculated mean: 0,03905 Pa at 60°C - Executive summary:
The vapour pressure of the test item was determined at nine different temperatures (30, 45, 60, 75, 90, 105, 120, 135 and 150 °C) according to OECD 104 resp. EU A.4 using the effusion method (weight loss). All experiments 1 – 9 (nominal temperature 30 - 150 °C) showed no reproducible weight loss. When visible contaminations, caused by explosive evaporation of the test item, were observed, the cells were meticulously cleaned and weighed. This weight was used as initial weight for the subsequent measurements. To avoid bias, these measurements were not used for calculations.
As a calculation on base of the measured weight losses is not possible, the highest vapour pressure of the test item70% w/w Phytic acid (made from dermofeel PA)derived from all measurements, was stated as limit value.
For the calculation of the vapour pressure a molecular mass of 580.06 – 660.04 g/mol was used.
Limit Value for the molecular mass of 580.06 g/mol: Vapour pressure at 60 °C: 4.03* 10-02Pa
Limit Value for the molecular mass of 660.04 g/mol: Vapour pressure at 60 °C: 3.78* 10-02Pa
Reference
Vapourpressure was examined at nine different temperatures. No temperatures could be evaluated as they showed no reproducible weight loss.
As a calculation on base
of the measured weight losses is not possible, the highest vapour
pressure of the test item derived from
all measurements, was stated as limit value.
Limit
Value for the molecular mass of 580.06 g/mol: Vapour
pressure at 60 °C: 4.03* 10-02Pa
Limit Value for the molecular mass of 660.04 g/mol: Vapour pressure at 60 °C: 3.78* 10-02Pa
Note: For the calculation of the vapour pressure a molecular mass of 580.06 – 660.04 g/mol was used.
Description of key information
Limit value for vapour pressure at 60°C according to OECD 104 resp.EU A.4 using the effusion method (weight loss).
Key value for chemical safety assessment
- Vapour pressure:
- 0.039 Pa
- at the temperature of:
- 60 °C
Additional information
Vapourpressure was examined at nine different temperatures. No temperatures could be evaluated as they showed no reproducible weight loss.
As
a calculation on base of the measured weight losses is not possible, the
highest vapour pressure of the
test item,derived
from all measurements, was stated as limit value.
Limit Value for the molecular mass of 580.06 g/mol:
Vapour pressure at 60 °C: 4.03 * 10-02Pa
Limit Value for the molecular mass of 660.04 g/mol:
Vapour pressure at 60 °C: 3.78 * 10-02Pa
The resulting key value of 3.905 * 10 -02Pa at 60°C is a calculated mean.
