Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study

- Reliability:
- 1 (reliable without restriction)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- pre-test: slower heating rate: >1 °C/min, main test: Start-Temp.: 250 °C
- Deviations:
- yes
- Remarks:
- pre-test: slower heating rate: >1 °C/min, main test: Start-Temp.: 250 °C
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- yes
- Remarks:
- pre-test: slower heating rate: >1 °C/min, main test: Start-Temp.: 250 °C
- Principles of method if other than guideline:
- NA
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- capillary method
- Remarks:
- Metal block
- Key result
- Atm. press.:
- 1 013.25 hPa
- Decomposition:
- yes
- Remarks:
- before melting
- Decomp. temp.:
- 250 °C
- Sublimation:
- no
- Remarks on result:
- other: normal atmospheric pressure
- Conclusions:
- Using a linear heating rate of 1 °C/min the test substance was found to decompose before melting and therefore does not possess a melting point under the testing conditions (atmospheric pressure).
- Executive summary:
Using a linear heating rate of 1 °C/min the test substance was found to decompose at before melting and therefore does not possess a melting point under the testing conditions (atmospheric pressure).
When introduced to the apparatus at 250 °C the test substance was observed to decompose before melting. The vigorous nature of the decomposition reaction was presumably a result of the liberation of oxygen from potassium monopersulfate. This reaction was not observed in the preliminary test as the test substance was heated up to 250 °C at a slower rate.

Description of key information
Using a linear heating rate of 1 °C/min the test substance was found to decompose before melting and therefore does not possess a melting point under the testing conditions (atmospheric pressure).
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.
