Remarks:

Migrated information

Conclusions:

Based on the results obtained, triethanol amineacetate is considered "not highly flammable".

Executive summary:

In a guideline study, to GLP, triethanol amineacetate was heated in a water bath at 70°C until it became a paste. The paste was formed into a rope. A flame of a gas burner was applied to one end of the test substance rope for 2 min. The rope was visually interpreted for propagation of combustion either by burning with a flame or smouldering. If applicable, the time of burning over a distance of 200 mm was measured after the rope had burned a distance of 50 mm.

In contact with the flame of the gas burner, the test substance melted. After removal of the ignition source, no propagation of combustion of the test substance was observed.

Based on the results obtained, triethanol amineacetate is considered "not highly flammable".
