Description of key information

The substance consists of multiple different constituents with similar chemical structure: N,N'-ethane-1,2-diylbis(12-hydroxyoctadecanamide), N,N'-hexane-1,6-diylbis(12-hydroxyoctadecanamide) and N,N'-[1,3-phenylenebis(methylene)]bis(12-hydroxyoctadecanamide).There are no experimental data on the multi-constituent substance available. The individual constituents and mixtures of structurally similar bisamides are considered suitable read-across substances. Experimental results are provided from guideline studies for the read-across substances 1,3-bis[12-hydroxy-octadecamide-N-methylene]-benzene and 12-hydroxyoctadecanoic acid, reaction products with 1,3-benzenedimethanamine and hexamethylenediamine. Neither substance showed self-ignition up to 400 °C.

Since all constituents are structurally similar to each other, the properties of the substance being registered regarding self-ignition are expected to be comparable to the properties of the read-across substances. Therefore, we conclude that the substance being registered is not auto-flammable. Further testing is not considered necessary.
