Applicant's summary and conclusion
- Conclusions:
- Based on the experimental data the vapour pressures at 20, 25, and 50°C and using the Antoine equation resulted in vapour pressure values of 3.0 x 10E-4, 6.1 x 10E-4, and 1.4 x 10E-2 Pa at 20, 25, and 50°C, respectively. These values indicate a low volatility at ambient temperatures.
- Executive summary:
The vapour pressure of acylglycinate GCS-11 -T was investigated in a study conducted according to EU Method A.4. (Vapour Pressure) and OECD Guideline 104 (Vapour Pressure Curve) using the effusion method. Based on the experimental data the vapour pressures at 20, 25, and 50°C were calculated using the Antoine equation. The calculation resulted in vapour pressure values of 3.0 x 10E-4, 6.1 x 10E-4, and 1.4 x 10E-2 Pa at 20, 25, and 50°C, respectively. These values indicate a low volatility at ambient temperatures.
