- Orasol Black RLI

- Orasol Black RLI
- Details on test material:
- We do not have any details on the test material as the data was obtained from the ECHA using the 12 year rule. However below are a list of reasons why read across is suitable.
Due to the following reasons we wish to read across to the substance containing EC number 403-720-7:
The test substance and analogue substance (403-720-7) have very similar structural properties, the only difference between the two substances are that the counter cations are different. Valifast black contains a mixture of both ammonium and sodium cations whereas the analogue material (403-720-7) contains only tert C12-C14. alkylammonium ions. The ammonium and sodium ions present in Valifast black are unlikely to be toxic and their contribution to the toxicity of Valifast black is trivial. The anion components are the same for both substances and these appear to be key for the toxicity of the substance.
The relative density and the water solubility of the two substances are very similar as shown in the read across proposal (please find the read across proposal attached in section 13).
The analogue material EC 403-720-7 is not expected to accumulate in the environment. Due to the slightly higher log Pow (4.94 - 4.97) for the test material (Valifast Black 3810) the test substance has the potential to accumulate into the environment. As the test substance has a higher potential to acumulate into the environment, read across is still appropriate.
Neither the test material or the analogue material are classified with regards to the acute oral toxicity study. However both substances did provide a positive response both with and without metabolic activation in the Ames study.
It is our understanding that the ready biodegaradtion study is a key property of the substance and that the use of read across is not normally permitted. However in this case the analogue material (EC number 403-720-7) is not readily biodegaradable therefore we will be using a worst case result. Using read across will not cause any effect towards the classification or the labelling of Valifast black as the substance is not readily biodegaradble.
