Fatty acids, C9-13-neo-, calcium salts

Flammability

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 fatty acids, C9-13-neo-, calcium salts less combustible than the two tested substances.
- Testing for flammability in contact with water (A.12) is not considered to be required, because fatty acids, C9-13-neo-, calcium salts 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 fatty acids, C9-13-neo-, calcium saltss 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)

non flammable

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 those metal carboxylates with the highest hydro-carbon content: manganese bis(2-ethylhexanoate) (83.9 %) and fatty acids, tall-oil, calcium salts (89 %) in which the (i) Ca cation is present in the highest oxidation state (ii) the Mn is in a +II oxidation state, yielding a result of “not flammable”. Since fatty acids, C9-13-neo-, calcium salts 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), fatty acids, C9-13-neo-, calcium salts 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 fatty acids, C9-13-neo-, calcium salts 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 fatty acids, C9-13-neo-, calcium salts 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 fatty acids, C9-13-neo-, calcium salts 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 fatty acids, C9-13-neo-, calcium salts 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).
