Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The measurement of the vapour pressure of the registered substance Sucroglyceride C16-18 is technically not feasible due to residual water of ca. 3%, which cannot be removed by drying the substance. In case of measurement, the vapour pressure of water and not the substance itself would be measured. Thus, the vapour pressure of the main constituents was determined. The value used for chemical safety assessment is 0.0224 Pa at 25°C (vapour presssure of Glycerol), which can be considered as the worst case value as it is the highest vapour pressure in the substance.
Key value for chemical safety assessment
- Vapour pressure:
- 0.022 Pa
- at the temperature of:
- 25 °C
Additional information
The measurement of the vapour pressure of Sucroglyceride C16 -18 is technically not feasible due to residual water of ca. 3%, which cannot be removed by drying the substance. In case of measurement, the vapour pressure of water and not the substance itself would be measured. Thus, the vapour pressure of the main constituents was (a) calculated using EPI suite (MPBPVP v1.43) and (b) taken from a peer reviewed database (HSDB database).
The calculation resulted in 4.71E-14 Pa for Sucrose, 0.011 Pa for Glycerol, 7.36E-03 Pa for Palmitic acid, 0.0011 Pa for Stearic acid, 9.51E-08 Pa for the monoglyceride C16 and 1.7E-07 Pa for the monoglyceride C18.
For Glycerol, Palmitic acid and Stearic acid a database search (HSDB database) was performed. The values for vapour pressure (at 25°C) obtained from HSDB database were 1.68E-04 mm Hg (0.022 Pa) for Glycerol, 3.80E-07 mm Hg (5.07E-05 Pa) for Palmitic acid, and 4.28E-08 mm Hg (5.6E-06 Pa) for Stearic acid.
The value used for chemical safety assessment is 0.022 Pa at 25°C (vapour pressure of Glycerol), which can be considered as the worst case value as it is the highest vapour pressure in the substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
