Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- CLP: not classified
DSD: not classified - Executive summary:
The study objective was to determine the irritant effects of the target substance on eyes of albino rabbits (strain Crl:KBL(NZW)BR) (Gmelin, 2008). The study was conducted according to OECD TG 405 and GLP and is assigned as Klimish 1. 0.1 mL of the pure liquid test substance was placed into the conjunctival sac of one eye of the first animal after having gently pulled the lower lid away from the eyeball. The lids were gently held together for about one second in order to prevent loss of the test compound. The other eye, which remained untreated, served as control. The eye was rinsed approximately 24 hours following instillation. There was no severe irritation observed in the first animal, therefore two further rabbits were treated in the same manner. Eye irritations were scored and recorded approximately at 1, 24, 48 and 72 hours post application. Irritation indices were observed after 72 h, therefore the animals were monitored on day 7, 14 and 21 after application until the changes had completely subsided. The degree of ocular lesions was recorded as specified by Draize. The body weight of each animal was recorded at the beginning of the study. If clinical findings other than eye irritations occur they were recorded daily.
The mean scores at 24 -h, 48 -h, and 72 -h reading time points were 0.0 for corneal opacity and iritis for three animals. Redness sconjunctivae scores were 1.3, 1.3 and 1.0 and chemosis conjunctivae scores were 0.3, 1.0 and 0.3 for animal 1, 2, and 3, respectively. All irritation reactions were fully reversible within 7 days. There were no systemic intolerance reactions. According to the classification criteria (CLP/GHS), the substance is not irritating to eyes.
