Eye irritation
Administrative data
- Endpoint:
- eye irritation: in vivo
- Type of information:
- read-across based on grouping of substances (category approach)
- Adequacy of study:
- key study
- Study period:
- 20 september 1993 - 4 october 1993
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- Read-across (Category)
The available in vivo data on this endpoint is consistent within the group. Two in vivo eye irritation studies are available on two of the substances. The effects seen, such as redness in conjunctiva and cornea, were reversible and mild, therefore not generating any classification. Using this data for read across within the group would be extrapolating data to the extremes of the group. In order to support this read across, in vitro eye irritation studies on all the four substances were performed, both in EpiOcular and Isolated Chicken Eye test. Also the in vitro tests results were consistent within the group, indicating a mild to irritating results. There is no possibility to evaluate the reversibility of the effects seen in in vitro studies. The in vitro tests EpiOcular and Isolated chicken eye tests are considered to over-predict the actual eye irritation potential of the substance shown in the rabbit tests. The effects in the in vitro studies are mild, and do not indicate Cat 1 classification for eye irritation. Currently in vivo data is required in order to classify eye irritation Cat 2. The weight of evidence from the available eye irritation data on this group of substances indicates no classification for eye irritation.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- A single instillation of the technical product into the eye of the rabbit elicited corneal opacificaton, iridial inflammation and well-defined conjunctival irritation. All reactions had resolved 3 or 7 days after instillation. The composition of the technical product is 40% active ingredient and 60 % water. The observed results do not warrant classification according to GHS.
- Executive summary:
A study was performed to assess the eye irritation potential of a technical product to the rabbit. The method followed was that described in EEC Methods for the determination of toxicity, Amex to Directive 92/69/EEC (OJ No. L383A, 29.12.92), Part 3, Method B.5. Acute toxicity (eye irritation). Three rabbits were each administered a single ocular dose of 0.1 ml of the test substance and observed for seven days after instillation. A single instillation of the technical product into the eye of the rabbit elicited corneal opacificaton, iridial inflammation and well-defined conjunctival irritation. All reactions had resolved 3 or 7 days after instillation. The observed results do not warrant classification according to GHS.
