Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- White liquor is not likely to have explosive properties and no classification is required.
- According to the REACH Regulation (EC) No 1907/2006 Annex VII, the test EC 440/2008, A.14 does not need to be conducted if there are no chemical groups associated with explosive properties present in the molecule, or the exothermic decomposition energy of the test substance is less than 500 J/g and the onset of exothermic decomposition is above 500 °C.
- The molecular/ionic structure of White liquor and its constituens do not indicate the presence of highly reactive or unstable groups. The known structure does not indicate that White liquor would present a danger of explosion when submitted to the effect of a flame or shock under the conditions of the test as described in Test Guideline A.14 of EC Regulation No 440/2008.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
White liquor is always manufactured as an aqueous solution of inorganic salts. None of these salts, in wet or dry form, are classifiable as explosive according to C&L rules or presents any other danger of explosion in normal hadling conditions. The dry solids/water ratio of the representative sample was 17/83 % by weight. Dry salts, e.g. sodium sulphide, may be hazardous and explode if it is heated to very high temperatures.
Justification for classification or non-classification
White liquor is not likely to have explosive properties. No classification is required.
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.
