Description of key information

The vapor pressures of the two main components of Keto Gulonic Acid Greens were estimated. The value for KGA is used for the CSA.

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
25 °C

Additional information

The vapor pressures of the two main components of Keto Gulonic Acid Greens were estimated to be

 

2-Keto-L-gulonic acid anhydrous

8.8 x 10-8Pa at 25 °C

Vitamin C

1.5 x 10–8Pa at 25 °C

  

based on the boiling point calculated and using the Modified Watson Correlation.
