Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

Endpoint:
relative self-ignition temperature (solids)
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is a solid having a melting point <= 160°C
Justification for type of information:
The melting point of the substance is very close to the cut-off for data waiving (177.4°C).
During the melting point study, the temperature was raised up to 372°C. During this study, decomposition and/or reaction of the substance occurred and a brown molten residue remained. No ignition of the substance was observed.
Additionally, the self-heating study performed at temperatures up to 140°C showed no self-ignition of the substance.
Therefore, the substance is considered to have no self-ignition temperature.

Adequacy of study:
key study
Study period:
2019
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
UN Manual of Tests and Criteria: Test N.4 (Test method for self-heating substances)
Version / remarks:
2015
Deviations:
no
GLP compliance:
yes
Test procedure:
100 mm sample cube at 140°C
Max. temp. reached:
140
Induction time (h):
24
Result:
negative outcome (no effect observed)
Interpretation of results:
GHS criteria not met
Conclusions:
Self-heating of CH02672 was determined in accordance with UN Test N.4 “Test Method for Self-heating Substances”.
From the negative result obtained at 140°C using a 10 cm sample cube, it was concluded that CH02672 is not a self-heating substance.
