Results and discussion
In vivo
Results
- Irritation parameter:
- overall irritation score
- Basis:
- mean
- Time point:
- other: 24, 48, 72 h
- Score:
- 49.8
- Max. score:
- 110
- Reversibility:
- not fully reversible within: 8 days
- Irritant / corrosive response data:
- Eight days after application of the test substance, no repair of the eye damages was observed, with a trend for deterioration. Phenyl isocyanate is therefore highly irritant to the eyes.
- Other effects:
- No repair of the effects within 8 days, with a trend for further deterioration
Any other information on results incl. tables
Eight days after application of the test substance, no repair of the eye damages was observed, with a trend for deterioration.
Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (irreversible effects on the eye) based on GHS criteria
- Conclusions:
- Eight days after application of the test substance, no repair of the eye damages was observed, with a trend for deterioration. Phenyl isocyanate is therefore classified as highly irritant. According to CLP classification criteria (Regulation (EC) No 1272/2008) a classification as Eye Damage 1 is justified.
- Executive summary:
100 µl phenylisocyanate was applied into the conjunctival sac of the right eye of 6 rabbits. Reading was carried out 24, 48 and 72 h after start of application of the test substance. A primary irritation score of 49.8 (of 110) was found. Eight days after application of the test substance, no repair of the eye damages was observed, with a trend for deterioration. Phenyl isocyanate is therefore classified as highly irritant.
