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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

EC number: 268-612-2 | CAS number: 68131-30-6 A solution obtained by dissolving the chemicals recovered in the alkaline pulping process in water.

Description of key information
Green liquor is always manufactured as an aqueous solution of alkaline inorganic salts. None of these salts, in wet or dry form, are classifiable as explosive. In dry forms, these salts may pose a danger of explosion if heated.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Justification for classification or non-classification
The molecular/ionic structure of GL and its constituents do not indicate the presence of highly reactive or unstable groups. The known structure does not indicate that GL presents 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.
Green liquor is always manufactured as an aqueous solution of alkaline 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 handling conditions. Dry salts e.g. Na2S may be hazardous and explode if it is heated to very high temperatures.
The available information is adequate to decide that green liquor should not be classified for explosivity and there is no need for further actions regarding this assessment end point.
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.
