Description of key information
Read-across from lead tetroxide:
The read-across approach used falls under RAAF Scenario 2: analogue approach for which the hypothesis is based on different compounds with the same type of effect.
The absence of effects obtained in a study conducted with the source substance, lead tetroxide, is used to predict the same absence of effects that would be observed in a study with the target substance if it were to be conducted.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
On the basis of read-across from lead tetroxide, together with long-term industrial handling experience, testing of Fatty acids, C16 -C18, lead salts is not required, in accordance with Regulation (EC) No 1907/2006, Annex XI, Section 1.5: read-across of results and conclusion on classification for lead tetroxide to fatty acids, C16 -C18, lead salts is justifiable, under RAAF scenario 2.
Justification for classification or non-classification
Fatty acids, C16 -C18, lead salts does not require classification for oxidising properties based on a comparison of the oxidation state with a tested substance, orange lead, which was concluded "non oxidising", and long-term industrial handling experience.
In the sense of classification for supply and transport an oxidising solid is a solid which, while in itself not necessarily combustible, may – generally by yielding oxygen – cause or contribute to the combustion of other material. An oxidising agent is therefore normally found in one of its higher possible oxidation states.
Testing according to EU Method A.17 was carried out on lead tetroxide (orange lead; Pb3O4) in 2005. From the test results it is concluded that orange lead does not exhibit oxidising properties.
In the test substance, lead tetroxide, the lead is present in two oxidation states +II and +IV. However, the lead in the target substance is only in the oxidation state +II and is thus intrinsically less oxidising. The carboxylate ion moiety of the long-chain fatty acid structures in this substance is also stabilised by its delocalised electron density in the form of resonance structures and is therefore less likely to yield an oxygen; the long chain C16-C18 groups provide a further increased electron density to the carboxylate moiety. The anion forms a strong ionic bond to the lead ion, which increases the stability of the structure and further decreases the likeliness of oxygen donation..
Testing of fatty acids, C16 -C18, lead salts is not required, in accordance with Regulation (EC) No 1907/2006, Annex XI, Section 1.5: read-across of results and conclusion on classification for lead tetroxide to the target substance is justifiable, under RAAF scenario 2.
