Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Calculated vapour pressure at 20°C: <0.001 Pa
Key value for chemical safety assessment
Additional information
According to Column 2 of REACH Annex VII, the vapour pressure of a substance may be determined using (Q)SAR modelling if melting point of the substance is between 200 and 300°C. As the melting point of Allantoin was determined to be 229°C, the vapour pressure was assessed using (Q)SAR calculation via MPBPWIN v. 143.
Calculated vapour pressures are: 8.9 x 10-8 Pa (solid) and 1.8 x 10-5 Pa (subcooled liquid). These very low values are considered negligible. For ecotoxicological purpose the vapour pressure is therefore quoted as <0.001 Pa.
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.
