Eye irritation
Administrative data
- Endpoint:
- eye irritation, other
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Study period:
- 03 Oct 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
- Justification for type of information:
- The (Q)SARs models used in this assessment have been evaluated by the Joint Research Centre (JRC) and the scientific validity of each software established according to five principles recommended by OECD and ECHA for regulatory purposes (Annex XI of the REACH).
At present, a summary of appropriate information on the (Q)SAR models, based on the topics listed below, is not available in a specific reporting format.
• • Endpoint, algorithm
• • Domain of applicability
• • Measures related to goodness-of-fit
• • Robustness
• • Predictivity and mechanism
However, the adequacy and reliability of each (Q)SAR prediction was checked for each endpoint following the procedures outlined in REACH Annex XI (1.3) in terms of suitability of the model (reliability, relevance for the purpose), applicability of the model to the substance of interest and adequacy of the predicted endpoint for classification and labelling.
See attached justification for further information.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Remarks:
- It was concluded based on the weight of evidence that it is not possible to classify the substance of interest for eye irritation/ corrosion.
- Conclusions:
- No eye irritation data was found in both in-house or external databases for the target and source molecules, although the HSDB database -occupational hazards- reports possible contact burns to the skin, related to the use of 1-nitronapthalene.
This substance is used in the industry as a corrosion inhibitor, which suggests an extreme acidity profile contrary to that determined experimentally for the target substance (pH = 5.7). Therefore, it is not appropriate to use pH as the sole criterion for read-across analyses. Consequently, decision logic relied on the following aspects was applied to support the classification of this endpoint: i) the target substance is not corrosive (measured pH of 5.8); ii) no eye irritation data from animal studies are available for the target or source molecules, and iii) the (Q)SAR predictions did not provide sufficient basis for the presence of irritating potential.
Overall, it was concluded based on the weight of evidence that it is not possible to classify the substance of interest for eye irritation/ corrosion. - Executive summary:
