ENVIRONMENTAL CONDITIONS
- Temperature: 19 - 22°C
- Humidity 52 - 70%
- Air changes: Approximately 16 air changes per hour.
- Photoperiod: 12 hours light/12 hours dark. - Vehicle:

- Single exposure
- Observation period (in vivo):
- 72 hours
- Number of animals or in vitro replicates:
- 3 male rabbits
- Details on study design:
- After the acclimatisation period, both eyes of each rabbit were examined with the aid of a slit-lamp. Only those rabbits without eye defects or signs of irritation were used. A quantity of 0.1 mL CAPA 203 was placed in the conjunctival sac of the left eye by gently pulling the lower lid away from the eyeball to form a cup into which the test substance was placed. The lids were then gently held together for a short period and the rabbit was released. The other eye remained untreated and served as a control. Readings of reactions were made in all three rabbits at 1, 24, 48 and 72 hours after treatment. Scoring of the irritation was performed according to the grades given in the Draize method.

- Interpretation of results:

- Conclusions:
- There were no signs of irritation in any rabbit at any timepoint in this study. The read-across substance CAPA 203 was not shown to be an eye irritant and does not therefore require classification for eye irritation according to the CLP Regulation. A similar lack of eye irritation potential is therefore predicted for CAPA 2047A
- Executive summary:
A study to assess the primary eye irritation of the read-across substance CAPA 203 (2 -oxepanone, polymer with 1,4 -hexanediol) in rabbits was conducted in accordance with OECD Guideline 405 and GLP. 0.1 mL CAPA 203 was instilled into the conjunctival sac of one eye of each of three male rabbits. T he eyes of the rabbits were examined and ocular reactions were graded at intervals up to and including 72 hours after treatment. Following the observation period, there were no signs of irritation observed in the three rabbits. A similar lack of eye irritation potential is therefore predicted for CAPA 2047A
