Applicant's summary and conclusion
- Conclusions:
- The calculation of the vapour pressure based on experimental data yielded values of 1.4 x 10E-7 (at 20°C), 2.5 x 10E-7 (at 25°C), and 3.2 x 10E-6 hPa (at 50°C).
- Executive summary:
The vapour pressure of acylglycinate GCK-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 measurements in the range between 20 and 127°C, remarkable vapour pressures were found at temperatures > 74°C. Taking into account 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 1.4 x 10E-7, 2.5 x 10E-7, and 3.2 x 10E-6 hPa at 20, 25, and 50°C, respectively. These values indicate a low volatility at ambient temperatures.
