Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Lithium hydroxide anhydrous and monohydrate are non-flammable according to the conducted study. Flammability upon contact with water: The chemical structures of lithium hydroxide anhydrous and lithium hydroxide monohydrate indicate that there are no groups associated with flammability properties (Ref.: R.7a: Guidance on information requirements and chemical safety assessment, EU-Document (May 2008)). Further, experience in handling and use does not indicate flammability upon contact with water. Further, the chemical structures of lithium hydroxide anhydrous and lithium hydroxide monohydrate indicate that there are no groups associated with pyrophoric properties. The test substances do not contain any chemical group that might lead to spontaneous ignition shortly after coming into contact with air at room temperature (Ref.: R.7a: Guidance on information requirements and chemical safety assessment, EU-Document (May 2008)). Based on experience in handling and use there is also no indicator for pyrophoric properties. Further, lithium hydroxide and its monohydrate do not meet the criteria for self-heating substances.
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
A flammability study was performed according to UN Recommendations on the Transport of Dangerous Goods, Manual of Test and Criteria, N1: Test Method for readily combustible solids, subsection 33.2.1.4. Based on this, lithium hydroxide anhydrous and its monohydrate are non-flammable. (FMC, 2010)
Justification for classification or non-classification
The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. Based on available data on flammability, the test item is not classified according to Regulation (EC) No 1272/2008 (CLP), as amended for the tenth time in Regulation (EU) No 2017/776.
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.
