Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Testing of flammability does not appear scientifically necessary according to Regulation (EC) No 1907/2006, Annex XI, Section 1.
- A test on the flammability according to EC method A.10 was recently conducted for two solid substances (within the MCRC substance portfolio) representing those metal carboxylates with the highest hydro-carbon content: fatty acids, C9-13-neo-, zinc salt (85 %) and fatty acids, C14-18 and C16-18-unsatd., barium salts (82 %) in which the metal cation is present in the highest oxidation state, yielding a result of “not flammable”.
Since barium bis(2-ethylhexanoate) represents 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), barium 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.
- Testing for flammability in contact with water (A.12) is not considered to be required, because barium 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 barium 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).

Additional information
A test on the flammability according to EC method A.10 was recently conducted for two solid substances (within the MCRC substance portfolio) representing those metal carboxylates with the highest hydro-carbon content: fatty acids, C9-13-neo-, zinc salt (85 %) and fatty acids, C14-18 and C16-18-unsatd., barium salts (82 %) in which the metal cation is present in the highest oxidation state, yielding a result of “not flammable”. Since barium bis(2-ethylhexanoate) represents 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), barium 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.
Testing for flammability in contact with water (A.12) is not considered to be required, because barium 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 barium 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 A.13 (pyrophoric properties of solids and liquids) is not considered to be required, since barium 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 barium bis(2-ethylhexanoate) does not ignite in contact with air. For the reason given above, no classification and labelling of barium bis(2-ethylhexanoate) is necessary (in accordance with Regulation (EC) No 1907/2006), Annex XI, Section 1).
Justification for classification or non-classification
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
