Conclusions:
According to the performed QSAR prediction the vapour pressure of L-aspartic acid is 3.5E-05 Pa at 25°C. The contained magnesium ion is not considered to rise the vapour pressure.
Executive summary:

According to the performed QSAR prediction the vapour pressure of L-aspartic acid is 3.5E-05 Pa at 25°C. The contained magnesium ion is not considered to rise the vapour pressure.

Description of key information

Additional information

The vapour pressure for L-aspartic acid was determined using Estimation Programs Interface Suite™ for Microsoft® Windows v4.11. US EPA, MPBPWIN v1.43 model. The vapour pressure is 3.5E-05 Pa at 25 °C. The additionally contained magnesium ion in the test item is not considered to elevate the vapour pressure due to the ionic structure. This assumption is substantiated by the measured decomposition temperature, indicating no boiling/evaporation up to decomposition temperature.
