Description of key information
Multiple Quantitative Structure Activity Relationship (QSAR) models were used to predict the Skin Sensitization potential of the test item Tetrasodium 1,3,6,8-pyrenetetrasulfonate.
The final skin sensitization result was predicted by applying a consensus method on the reliable results derived for individual models.
The final Skin Sensitization result predicted for Tetrasodium 1,3,6,8-pyrenetetrasulfonate assigned by the study investigator: non sensitizing to the skin. The final QSAR result can be associated with a Klimisch score:K2
The same method was used to predict the Skin Sensitization potential of the analogue test item trisodium 8-hydroxypyrene-1,3,6-trisulfonate.
The final skin sensitization result predicted for trisodium 8-hydroxypyrene-1,3,6-trisulfonate assigned by the study investigator: non sensitizing to skin. Klimisch score assigned by the study investigtor for the final prediction: K2
Test results published on the ECHA website provided a conclusion of non sensitizing to skin for Skin Sensitization potential for the analogue test item trisodium 8-hydroxypyrene-1,3,6-trisulfonate.

Read-across information
REPORTING FORMAT FOR THE ANALOGUE APPROACH
1. HYPOTHESIS FOR THE ANALOGUE APPROACH
STRUCTURAL SIMILARITY
Both the substances share the same carbon skeleton, which is pyrene. The query substance holds four sulfonates groups while the proposed analogue has one hydroxy group replacing a sulfonate. Both sulfonate and hydroxy groups are hydrophilic in nature. However, the hydroxy group is only ionised at high pHs (pKa of phenol is around 10) while the sulfonate group would remain ionised over the whole range of aqueous pHs. Therefore, Read-Across substance is expected to be slightly less hydrophilic and more volatile than the query substance, which is confirmed by the log KOW and vapour pressure studies.
Both the substances are expected to be stable in pure form or in water, and they are expected to be not volatile (high boiling point, low vapour pressure), highly hydrophilic (low log KOW, high water solubility) due to the presence of four strongly hydrophilic groups.
MECHANISMS OF ACTION PREDICTION
The mechanisms of action of both substances are predicted as follows:
Substance MechoA MechoA detail
Query 1.1 non-polar narcosis for all species
Read-Across 1.2 polar narcosis for all species
2. SOURCE AND TARGET CHEMICAL(S) (INCLUDING INFORMATION ON PURITY AND IMPURITIES)
See Test material sections of the source and target records for details.
3. ANALOGUE APPROACH JUSTIFICATION
DISCUSSION AND CONCLUSION
Therefore, both the structures are expected to have very similar (eco)toxicological profile. Moreover, Read-Across substance being less hydrophilic than the query substance and having a more toxic MechoA, the prediction of (eco)toxicological endpoints will be a worst-case scenario, because the less hydrophilic a substance is, the more toxic it is.
Consequently, trisodium 8-hydroxypyrene-1,3,6-trisulfonate is judged to be a good Read-Across for tetrasodium 1,3,6,8-pyrenetetrasulfonate. - Guideline:

Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not sensitising)
- Additional information:
Both structures for the substancesTetrasodium 1,3,6,8-pyrenetetrasulfonate and8-hydroxypyrene-1,3,6-trisulfonate are expected to have very similar (eco)toxicological profiles. Moreover, the Read-Across substance being less hydrophilic than the query substance and having a more toxic MechoA, the prediction of (eco)toxicological endpoints will be a worst-case scenario, because the less hydrophilic a substance is, the more toxic it is.
Consequently, trisodium 8-hydroxypyrene-1,3,6-trisulfonate is judged to be a good Read-Across for tetrasodium 1,3,6,8-pyrenetetrasulfonate.
Comparison with the QSAR results for the analogue substance, together with the available data on the analogue substance indicate that testing using 8-hydroxypyrene-1,3,6-trisulfonate would not be expected to show evidence of sensitization.
