Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- SCP liquor is not likely to have explosive properties based on differential scanning calorimetry (DSC), and no classification is required.
- According to column 2 of Annex VII in the REACH regulation, the test for explosiveness (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.
- SCP liquor is a UVCB-substance and contains different inorganic and organic compounds. An examination of the chemical structure is not possible and therefore an experimental examination using differential scanning calorimetry (DSC) was performed.
- The DSC curve of the test substance shows no exothermic peaks with relevant reaction enthalpies between 20 °C and 550 °C. Therefore explosive properties of SCP liquor are unlikely.

Additional information
According to column 2 of Annex VII in the REACH regulation, the test for explosiveness (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 DSC curve of the test substance shows no exothermic peaks with relevant reaction enthalpies between 20 °C and 550 °C. Therefore explosive properties of SCP liquor are unlikely.
Justification for classification or non-classification
SCP liquor is not explosive based on its exothermic decomposition energy in differential scanning calorimetry (DSC). Therefore no classification for explosiveness 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.
