Zinc bis(2-ethylhexanoate)

Flammability

Link to relevant study record(s)

Reference

Reference 1

Endpoint:

pyrophoric liquids

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 2

Endpoint:

flammable liquids: obsolete as covered by section 'Flash point'

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the substance is a liquid

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

Testing of flammability does not appear scientifically necessary according to Regulation No (EC) 1907/2006, Annex XI, Section 1.

- Testing of flammability of solids (EU Method A.10) and gases (EU Method A.11) is not considered to be required, since zinc bis(2-ethylhexanoate) is a liquid substance

- Testing for flammability in contact with water (EU Method A.12) is not considered to be required, because zinc 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 (EU Method A.13) is not considered to be required, since zinc 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

Testing of flammability of solids (EU Method A.10) and gases (EU Method A.11) is not considered to be required, since zinc bis(2-ethylhexanoate) is a liquid substance (with a melting point of < -60 °C) and not a solid or gas (in accordance with Regulation (EC) No 1907/2006, Annex XI, Section 1).

Testing for flammability in contact with water (EU Method A.12) is not considered to be required, because zinc 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 (in accordance with Regulation (EC) No 1907/2006, Annex XI, Section 1). Furthermore, long-term industrial experience in practical handling of zinc 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.

This test according to EU Method A.13 (pyrophoric properties of solids and liquids) is not considered to be required, since zinc 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). Furthermore, experience in handling shows that zinc bis(2-ethylhexanoate) does not ignite in contact with air. For the reason given above, no classification and labeling of the substance is necessary (in accordance with Regulation (EC) No 1907/2006), Annex XI, Section 1).

Justification for classification or non-classification

Zinc bis(2-ethylhexanoate) is not flammable. Therefore, classification is not required for flammability according to CLP Regulation (EC) No 1272/2008 and its subsequent amendments.
