- GR-50-1408 is the Givaudan identification code which was employed for ROSYFOLIA during the early, developmental and testing period.
- Key result
- Temp.:
- 20 °C
- Vapour pressure:
- 0.5 Pa
- Remarks on result:
- other: Vapour Pressure derived from average of detected headspace concentrations of test item at 24, 28, 48 and 52 hours.
- Conclusions:
- The vapour pressure of the test material GR-50-1408 has been determined to be 0.5 Pa at 20°C using the Gas Saturation method.
Therefore vapour pressure of GR-50-1408: 0.5 Pa at 20°C.
Reference
Headspace vapour concentrations of GR-50-1408 as found after an equilibration time of 24h, 28h, 48h and 52h are exposed in the below table.
The vapour pressure at 20°C was calculated from the average headspace concentration using the following equation:
p = W/V – RT/M
p is the vapour pressure in Pascal (Pa)
W is the mass of test substance in the aspirated volume (g)
V is the aspirated volume (volume of the burette) (m³)
R is the universal gas constant (8.314 J-mol-1-K-1)
T is the test temperature (K)
M is the molecular mass of the test substance (g mol-1)
Equilibration time(h) | Headspace concentration (g/m³) |

24 | 0.0426 |
28 | 0.0396 |
48 | 0.0446 |
52 | 0.0352 |

Average | 0.0405 |
Description of key information
The vapour pressure of the test material GR-50-1408 has been determined to be 0.5 Pa at 20°C using the Gas Saturation method.
Therefore vapour pressure of GR-50-1408: 0.5 Pa at 20°C.
Key value for chemical safety assessment
- Vapour pressure:
- 0.5 Pa
- at the temperature of:
- 20 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
