No combustion and no propagation of fire was observed - the substance melted.
Stage 1:
The test substance was added to a dish containing distilled water. No liberation of gas could be observed. Attempts to ignite the gas phase above the dish with the flame of a burner produced negative results.
Stage 2:
The test substance was introduced to a filter paper floating on the surface of the distilled water contained in a dish. No liberation of gas could be observed. Attempts to ignite the gas phase above the filter paper produced negative results.
Stage 3:
A few drops of water were added to a sample of the test substance. No liberation of reaction gasses could be observed. Attempts to ignite the gaseous phase produced negative results.
Stage 4:
Water (approx. 100 mL) was added from a dropping funnel to 12 - 19 g samples of test substance. Three trials were performed. Test sample weights: 15.6 g (trial 1), 12.1 g (trial 2), 19 g (trial 3).
Results (total quantities of liberated gas in cm³, total time 405 min):
Trial 1: 0.6 at t = 0 and at t = 15 min; 0 afterwards
Trial 2: 0.4 at t = 0; 0 afterwards
Trial 3: 0 over the whole period
Minor gas evolution could only be observed in two trials immediately after water addition. The gas production based on one kilogram of test substance and a one hour test period was considerably less than 1 L/kgh in all trials.
The test item does not liberate gases in hazardous amounts in case of contact with water or humid air when tested according to this procedure.
The test item exhibits no pyrophoric properties at ambient temperature in the sense of Test Procedure EC A.13.
According to the chemical structure of Imidacloprid no chemical reaction of the test item in contact with water is expected. The molecule contains no chemical bond which is hydrolysable at room temperature or moderate temperatures above room temperature. Therefore a reaction with water can be excluded. Due to this fact the test item does not form hazardous gases in contact with water.
The test item Imidacloprid (NTN 33893) is not regarded as hazardous in
the sense of the consolidated version of Council Directive 67/548/EEC,
Annex V, test A.12.
In the chemical structure of Imidacloprid no C-H-bond activated for oxidation by air is present. All other chemical bonds in the given molecule are stable in the presence of air. Due to the chemical structure of the test item pyrophoric properties in contact with air can be excluded.
The test item Imidacloprid (NTN 33893) has no pyrophoric properties in
the sense of the consolidated version of Council Directive 67/548/EEC,
Annex V, test A.13.
Description of key information
non-flammable on ignition (EU A.10)
non-pyrophoric (EU A.13)
does not liberate hazardous gases on contact with water (EU A.12)
not self-heating
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
The substance is non-flammable on ignition as determined in the test according to EU A.10. The solid test item just melted in contact with the ignition source.
The substance is non-pyrophoric as determined in the test according to EU A.13. Non-pyrophoricity can also be deduced from the molecular structure.
The substance does not liberate hazardous gases on contact with water, as determined in an experiment according to EU A.12. This fact is confirmed by an analysis of the molecular structure.
The substance is not self-heating. It is completely molten at the temperature 160 °C.
Justification for classification or non-classification
The available data on flammability of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008 and are therefore conclusive but not sufficient for classification: No propagation of burning in a test according to EU Method A.10 was observed - the test item just melted. Based on the results of the tests EU A.13 and EU A.12 and the chemical structure, pyrophoricity and flammability on contact with water, respectively, are not expected. Based on the melting point (< 160 °C) the substance is not self-heating.
