Description of key information

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

- Testing of flammability of solids (A.10) and gases (A.11) is not considered to be required, since flammability tests with two metal carboxylates with the highest carbon content did not show flammable properties, thus strontium bis(2-ethylhexanoate) is less combustible than the two tested substances.

- Testing for flammability in contact with water (A.12) is not considered to be required, because strontium 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 strontium 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

A test on the flammability according to EC method A.10. was recently conducted for two solid substances (within the RMC substance portfolio) representing

(i) one metal carboxylates with the highest hydrocarbon content and a cation in the highest oxidation state Ca(+II): fatty acids, tall-oil, calcium salts (89 % carbon content)

(ii) one metal carboxylate with a high carbon content and a cation in a low oxidation state Mn(+II): manganese bis(2-ethylhexanoate) (83.9 % carbon content).

Both tests yielded a result of “not flammable”. Since strontium bis(2-ethylhexanoate) is also an inorganic metal carboxylate containing the metal cation in the highest oxidised status and an anion of an acid which is less susceptible to any form of oxidation than the two tested substances (i.e. a lower hydro-carbon content ~ 81 %), strontium bis(2-ethylhexanoate) is thus intrinsically less combustible than the two tested substances. Further testing is no required in accordance with Regulation (EC) No 1907/2006, Annex XI, Section 1.1.1. A classification as flammable solid is not warranted.

Pyrophoric properties

Testing for pyrophoric properties is not considered to be required, since strontium 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 strontium 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 strontium 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 strontium 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

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