Reference 2

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

Reference 3

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

Description of key information

Testing of flammability does not appear scientifically necessary according to Regulation (EC) 1907/2006, Annex XI, Section 1.

- Testing of flammability of solids (A.10) is not considered to be required for inorganic metal salts in which (i) the cation is in its highest possible oxidation state (e.g. Zn2+) and which therefore is incapable of further reaction with oxygen, and (ii) the anionic component is similarly not capable of further reaction with oxygen. This substance can thus be designated as non-flammable. (Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance, section R.7.1.10.3).

- Testing for flammability in contact with water (A.12) is not considered to be required, because the substance 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 the test substance is stable at ambient temperature. The substance 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:

non flammable

Additional information

In accordance with section 1, Annex XI of Regulation (EC) 1907/2006 (REACH), the study does not need to be conducted. Testing of flammability is not considered to be required for inorganic metal salts in which (i) the cation is in its highest possible oxidation state (e.g. Zn2+) and which therefore is incapable of further reaction with oxygen, and (ii) the anionic component is similarly not capable of further reaction with oxygen. This substance can thus be designated as non-flammable. (Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance, section R.7.1.10.3). Furthermore, Octanoic acid, zinc salt, basic is classified in the supporting study of Wiedemann, 1999 as non flammable.

Testing for flammability in contact with water (A.12) is not considered to be required, because the substance 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) 1907/2006, Annex XI, Section 1). Furthermore, long-term industrial experience in practical handling of the substance 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 A.13 (pyrophoric properties of solids and liquids) is not considered to be required, since the test substance is stable at ambient temperature. The substance 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 the substance 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) 1907/2006), Annex XI, Section 1).

Justification for classification or non-classification

Octanoic acid, zinc salt, basic is not flammable. Therefore, classification is not required for flammability according to CLP Regulation (EC) No 1272/2008.
