Endpoint:

pyrophoric solids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

Reference 3

Endpoint:

substances / mixtures which in contact with water emit flammable gases

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance is known to be soluble in water to form a stable mixture

Description of key information

The flammability of the test substance is determined in a GLP key study which followed EU Method A.10 (Flammability (Solids)). The results show that nickel bis(2-ethylhexanoate) does not show flammable properties.

Testing for flammability in contact with water (A.12) is not considered to be required, because nickel bis(2-ethylhexanoate) does not contain groups that might lead to a reaction with water or damp air, leading to the development of dangerous amounts of gas or gases which may be highly flammable.

Testing of pyrophoric properties of solids and liquids (A.13) is not considered to be required, since nickel bis(2-ethylhexanoate) is stable at ambient temperature. It does not contain any chemical group that might lead to spontaneous ignition a short time after coming in contact with air at room temperature (approx. 20 °C).

 

Key value for chemical safety assessment

Flammability:

not classified

Additional information

Flammability

Burning time for the solid test substance was between 8 and 12 seconds. No propagation was observed in the preliminary test. Taking into account the results obtained during the preliminary test, no main test was performed.

The test item was not considered as highly flammable under our experimental conditions.

 

Pyrophoric properties

Testing for pyrophoric properties is not considered to be required, since nickel bis(2-ethylhexanoate) is stable at ambient temperature. It does not contain any chemical groups that might lead to spontaneous ignition a short time after coming in contact with air at room temperature (ca. 20 °C) . Furthermore, long-term industrial experience in handling shows that nickel bis(2-ethylhexanoate) does not ignite in contact with air (in accordance with Regulation (EC) No 1907/2006, Annex XI, Section 1).

 

Flammability in contact with water

Testing for flammability in contact with water is not considered to be required, because nickel bis(2-ethylhexanoate) does not contain groups that might lead to a reaction with water or damp air, leading to the development of dangerous amounts of gas or gases which may be highly flammable. Furthermore, long-term industrial experience in practical handling of nickel bis(2-ethylhexanoate) shows that it does not react with water, and recent experimental testing for water solubility has also not reported any formation of gases (in accordance with Regulation (EC) No 1907/2006, Annex XI, Section 1.2).

Justification for classification or non-classification

Nickel bis(2-ethylhexanoate) does not need to be classified according to CLP Regulation (EC) No 1272/2008 since it is not highly flammable.
