Type of information:
experimental study
Adequacy of study:
key study
Study period:
February 16-March 11, 2009
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
EU Method A.10 (Flammability (Solids))
GLP compliance:
yes (incl. QA statement)
Specific details on test material used for the study:
Name: Disodium hydroxy(sulfonato)acetate
Batch No.: 080129
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

The test item was heated with the flame of a propane burner. No ignition occurred. It was observed that the surface of the test item became black. The flame died when the burner was taken away. A sulphuric smell could be distinguished.

Since ignition did not occur within two minutes, the test item was classified as not highly flammable, and not determination of burning rate was necessary.

Interpretation of results:
other: not highly flammable
no classification based on flammability indicated.
Executive summary:

As no ignition with propagating flame was observed, the test item Disodium hydroxy(sulfonato)acetate should be considered as "not highly flammable".

Description of key information

The test item is considered as not highly flammable.

Key value for chemical safety assessment

not classified

Additional information

Justification for classification or non-classification

Being exposed to the flame of a gas burner, the test item's surface became black. No ignition could be observed. Upon removal of the gas burner, the flame died. Therefore, the test item is considered as non flammable.
