Applicant's summary and conclusion

Conclusions:
The calculation of the vapour pressure based on experimental data yielded values of 7.6 x 10E-9 (at 20°C), 1.6 x 10E-8 (at 25°C), and 4.0 x 10E-7 hPa (at 50°C).
Executive summary:

The vapour pressure of acylglycinate GCK-12H -T (dry matter) was investigated in a study conducted according to EU Method A.4 (Vapour Pressure), OECD Guideline 104 (Vapour Pressure Curve) and EPA OPPTS 830.7950 (Vapor Pressure) using the effusion method. Based on the experimental data vapour pressures of 7.6 x 10E-9 (at 20°C), 1.6 x 10E-8 (at 25°C), and 4.0 x 10E-7 hPa (at 50°C) were calculated using the Antoine equation. These values indicate a low volatility at ambient temperatures.
