Eye irritation
Administrative data
- Endpoint:
- eye irritation, other
- Remarks:
- Test performed before current guidelines
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- The study was conducted in March 1977.
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Remarks:
- Reliability 2 is assigned because although the study was conducted similar to the OECD TG 405, the guideline is not referenced and there is no documentation on experimental conditions. The study is also non-GLP. However, this did not influence the reliability of the results.

- Amount applied: 0.1 mL. Undiluted
- Duration of treatment / exposure:
- Single instillation on Day 1, exposure for 24 hours
- Observation period (in vivo):
- 7 days

- Details on study design:
- STUDY DESIGN
The test material was applied at 100% in 6 animals.
TREATMENT
Similar and in accordance with OECD 405 (1981). The test substance is placed in the conjunctival sac of one eye of each animal after gently pulling the lower lid away from the eyeball. The lids are then gently held together for about one second. The other eye serves at control.
REMOVAL OF TEST SUBSTANCE
-Washing: No
OBSERVATIONS
- Irritation:
The eyes of each animal were examined at 1, 24, 48 and 72 hours and 5 and 7 days after instillation of the test substance.
The irritation scores and a description of all other (local) effects were recorded. The irritation was assessed according to OECD 405 (1981).

4 - Slight erythema, slight discharge (Draize score = 1)
6 - Slight erythema, moderate discharge (Draize score = 1)
The scores in the table above are from F.H.S.A (a US test guideline) and are different from Draize scores. The wording is therefore used qualitatively to convert the F.H.S.A scores into Draize scores. Slight erythema is considered to be Draize 1.
Applicant's summary and conclusion
- Interpretation of results:
- other: Not an eye irritant
- Remarks:
- According to EU CLP 1272/2008 and its amendments.
- Conclusions:
- In an eye irritation study with rabbits, performed similar to OECD 405 (1981), essentially no irritation was observed. Based on the results of this study, test substance is not an eye irritant.
- Executive summary:
The substance was tested in an eye irritation test in rabbits similar to OECD 405 (1981). Six New Zealand albino rabbits were used. The volume applied was 0.1 ml and the material was applied undiluted. The scores in the test are from F.H.S.A (a US test guideline) and they are different from Draize scores. The wording is therefore used qualitatively to convert the F.H.S.A scores into Draize. Slight erythema and moderate discharge were seen in all animals at 1 hour, slight erythema and slight discharge were seen in 2/6 animals at 24 hours and none was seen after 48 hours. Discharge is not an endpoint for classification and labelling. Slight erythema is considered to be Draize 1. The mean conjunctiva score in the two affected animals was 0.3, based on the time points of 24, 48 and 72 hours, which is smaller than 2. Based on the results of this study, test substance is not an eye irritant.
