Miristalkonium chloride

Auto flammability

Link to relevant study record(s)

Reference

Endpoint:

auto-ignition temperature (liquids)

Remarks:

The auto-ignition temperature (for liquids and gases) was determined rather than the relative self-ignition temperature (for solids), as the test substance melts at low temperature (approximately 50°C).

Type of information:

experimental study

Adequacy of study:

key study

Study period:

From May 22, 2007 to July 20, 2007

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))

Version / remarks:

The auto-ignition temperature (for liquids and gases) was determined rather than the relative self-ignition temperature (for solids), as the test substance melts at low temperature (approximately 50°C)
