Test animals / tissue source
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or tissues and environmental conditions:
- Three New Zealand White strain rabbits in the weight range 2.5 to 3.1 kg, prior to treatment on Day 1 and approximately 11 to 14 weeks of age were
obtained from Froxfield Rabbits, Petersfield, Hampshire. The rabbits selected for the study were all acclimated to the laboratory environment.
The rabbits were individually housed in metal cages with perforated floors in Building R 14 Room 3. They had free access to tap water and SDS
Standard Rabbit Diet. Animal room temperature was maintained at approximately 19°C and relative humidity at 30-70%. Air exchange was
maintained at approximately 19 air changes per hour and lighting was controlled to give 12 hours of artificial light (0700-1900 hours) in each 24
hour period. All animals were observed daily for signs of ill health or toxic signs.
Test system
- Vehicle:
- unchanged (no vehicle)
- Amount / concentration applied:
- 0.1 ml
- Observation period (in vivo):
- 7 days
- Number of animals or in vitro replicates:
- 3
- Details on study design:
- The eyes of each animal were examined prior to instillation of the test substance to ensure that there was no pre-existing corneal damage or
conjunctival inflammation. A 0.1 ml aliquot of Redicote EN 611 was placed into the lower everted. lid of one eye of each animal. The eyelids
were then gently held together for one second before releasing. The contralateral eye remained untreated and served as a control.
Examination of the eyes was made after 1 hour and 1, 2, 3, 4 and 7 days after instillation. Observation of the eyes was aided by the use of a hand held
torch.

- Irritant / corrosive response data:
- All three animals gave a "positive" response. Corneal opacification developed in all three animals and was still present seven days after instillation,
when vascularisation of the cornea was also seen in one animal. Iridial inflammation was observed in all three animals. A diffuse, crimson colouration of the conjuntivae accompanied by swelling with partial eversion of the eyelids or with the eyelids about half-closed was seen in all three animals.
A copious discharge was observed in all three animals. All three animals were killed on humane grounds, seven days after instillation, due to the
severity of the ocular reactions.

Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (irreversible effects on the eye) based on GHS criteria
- Remarks:
- Migrated information
- Conclusions:
- Instillation of Redicote EN 611 into the rabbit eye elicited a positive response in all of the three treated animals according to OECD test criteria.
Severe ocular reactions were observed including vascularization of the cornea. Based on the severity of the reactions, the test article should be
classified as corrosive under GHS. - Executive summary:
The study was conducted to asseses the irritation potential of Redicote EN 611 when instilled into the eyes of rabbits in accordance with OECD 405. 0.1 ml was instilled into one eye of three rabbits. Eye were evaluated 1 hour after instillation and again 1, 2, 3, 4 and 7 days later.
Instillation of Redicote EN 611 into the rabbit eye elicited a positive response in all of the three treated animals according to OECD test criteria. Severe ocular reactions were observed including vascularization of the cornea. Based on the severity of the reactions, the test article should be classified as corrosive under GHS.
Label requirements under GHS: Symbol "Corrosion"; Signal word "Danger"; Hazard statement "Causes serious eye damage"
