Test animals / tissue source
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or tissues and environmental conditions:
- ConditionsEnvironmental controls for the animal room were set to maintain 18 to 24°C, a relative humidity of 40 to 70%, at least 10 air changes/hour, and a 12-hour light/12-hour dark cycle: the photoperiod was between 7:00 and 19:00 hrs daily. Any variations to these conditions were maintained in the raw data and had no effect on the outcome of the study. AccommodationAnimals were individually housed in labeled cages with perforated floors (Ebeco, Germany, dimensions 67 x 62 x 55 cm) and shelters (Ebeco, Germany, dimensions 40 x 32 x 23 cm).Acclimatization period was at least 5 days before start of treatment under laboratory conditions.DietPelleted diet for rabbits (Global Diet 2030 from Harlan Teklad®, Mucedola, Milanese, Italy) approximately 100 grams per day. Hay (TecniLab-BMI BV, Someren, The Netherlands) and wooden sticks (Swedish aspen wood, Bioservices, Uden, The Netherlands) were available during the study period.WaterFree access to tap water. Diet, water, bedding and cage enrichment evaluation for contaminants and/or nutrients was performed according to facility standard procedures. There were no findings that could interfere with the study.
Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other: untreated eye in each animal used as control
- Amount / concentration applied:
- 0.1 mL
- Duration of treatment / exposure:
- 24 hours
- Observation period (in vivo):
- 72 hours
- Number of animals or in vitro replicates:
- 3
- Details on study design:
- Each animal was treated by instillation of 0.1 mL of the test substance, in the conjunctival sac of one of the eyes after gently pulling the lower lid away from the eyeball. The lids were then gently held together for about one second to prevent loss of the test substance. The other eye remained untreated and served as the reference control.Immediately after the 24-hour observation, a solution of 2% fluorescein (Merck, Darmstadt, Germany) in water (adjusted to pH 7.0) was instilled into both eyes of each animal to quantitatively determine corneal epithelial damage. Immediately after fluorescein examination on Day 2, in order to provide a continued level of systemic analgesia, buprenorphine 0.01 mg/kg and meloxicam (Metacam®, Boehringer Vetmed GmbH, Ingelheim/Rhein, Germany) 0.5 mg/kg were administered by subcutaneous injection.After the final observation, two of the animals were sacrificed by intra-venous injection of Euthasol® 20% (AST Farma BV, Oudewater, The Netherlands). The other animal was removed from the study alive.

Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated informationCriteria used for interpretation of results: EU
- Conclusions:
- Slight irritant was observed in all animals at 1 hour, irritation was fully resolved in 1 animal at 24 hours, 2 animals at 48 hours and in all three animals at 72 hours.
- Executive summary:
Tris dipropylene glycol showed only limited eye irritation when tested neat in the rabbit. Based on these results it is not classified as an eye irritant.
