Eye irritation
Administrative data
- Endpoint:
- eye irritation, other
- Remarks:
- QSAR result
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Study period:
- 03-May-2018
- Reliability:
- 2 (reliable with restrictions)
- 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
- Remarks:
- Model result is reliable and recommended OECD principles for QSAR validation have been justified in the prediction report. However no QMRF or QPRF reports are currently available as model output.
- Justification for type of information:
- 1. SOFTWARE
iSafeRabbit models for skin and eye irritation by KREATiS
2. MODEL (incl. version number)
iSafeRabbit Skin Irritation model v1.1
3. SMILES OR OTHER IDENTIFIERS USED AS INPUT FOR THE MODEL
C1=CC=C(C=C1)C(=C2C=CC=C2)C3=CC=CC=C3
4. SCIENTIFIC VALIDITY OF THE (Q)SAR MODEL
Please refer to the attached prediction report for further information about the how the model fulfills the recommended OECD principles for QSAR validation.
5. APPLICABILITY DOMAIN
Please refer to the section 2.4 of the attached prediction report for further information.
6. ADEQUACY OF THE RESULT
Based on the model input (physicochemical properties), the model will predict the substance as non-irritant, irritant or corrosive provided all the functional groups in the query substance can be reliably predicted by the model. Please refer to the attached prediction report for further information.

Materials and methods
Test guideline
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The model determines whether the instilled dose of a chemical substance causes cytotoxicity, thereby responsible for corneal opacity and/or conjunctival redness. The dose applied and the physico-chemical properties of the test substance are the input of a series of algorihtms to determine: the substance concentration in the eye tissue and to establish if this concentration reaches a cytotoxic concentration. This concentration is plotted against the subcooled water solubility of the substance. The plot is subdivided into corrosive, irritant and non-irritant zones. The substance will fall into one of these zones, thereby allowing a classification.

Applicant's summary and conclusion
- Interpretation of results:
- other: non-irritating to the eye
- Conclusions:
- [cyclopenta-2,4-dien-1-ylidene(phenyl)methyl]benzene was predicted as non-irritant to eyes with iSafeRabbit Skin Irritation/Corrosion model according to Regulation (EC) No. 1272/2008 (CLP) and to GHS.
- Executive summary:
[cyclopenta-2,4-dien-1-ylidene(phenyl)methyl]benzene was provided as input to the iSafeRabbit Eye Irritation model v1.1. Based on the predicted results, the query substance is expected to be non-irritating to eyes according to Regulation (EC) No. 1272/2008 (CLP) and to GHS.
