Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Viscosity is a property of fluids. Since calcium oxide is a solid at ambient temperature (ca. 20°C) such a study does not need to be conducted for this substance (melting point: >450°C) (in accordance with section 1, Annex XI of regulation (EC) 1907/2006 (REACH)). Calcium carbonate is also a solid which remains solid at temperatures significantly above room temperature (melting point >825 °C). OECD Guideline no. 114 on the viscosity of liquids, indicates that the substances to be tested must be liquid at room temperature, and therefore a study of the viscosity of calcium carbonate is not required.
Key value for chemical safety assessment
Additional information
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.
