Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
auto-flammability
Type of information:
other: Expert assessment
Adequacy of study:
key study
Study period:
2010
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Assessment based on direct observations during handling of the substance and when mixing with water.
Qualifier:
no guideline followed
Principles of method if other than guideline:
Assessment based on properties of the substance and chemical structure.
GLP compliance:
no
Auto-ignition temperature:
> 400 °C
Atm. press.:
ca. 102.3 Pa
Remarks on result:
other: Data from boiling point assay, 4.3
Conclusions:
The substance is considered to be not classified as hazardous through autoflammability.
Executive summary:

The autoflammability of the registered substance was estimated via an assessment based on direct observations during handling of the substance and when mixing with water. Flash point is noted to be 198°C with no spontaneous combustion and during the boiling point investigation, decomposition was noted from 350°C with no major thermal decomposition up to the maximum tested temperature of 400°C. When mixed in water or damp air, there is no spontaneous combustion and the substance is considered thermally stable. The substance is considered to not be classified as hazardous through autoflammability.

 

Description of key information

The autoflammability of the registered substance was estimated via an assessment based on direct observations during handling of the substance and when mixing with water. Flash point is noted to be 198°C with no spontaneous combustion and during the boiling point investigation, decomposition was noted from 350°C with no major thermal decomposition up to the maximum tested temperature of 400°C. When mixed in water or damp air, there is no spontaneous combustion and the substance is considered thermally stable. The substance is considered to not be classified as hazardous through autoflammability.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
400 °C
