Test system

Vehicle:
unchanged (no vehicle)
Controls:
not required
Amount / concentration applied:
0.1 g, the test substance was applied undiluted
Duration of treatment / exposure:
single application to the left eye, no washing
Observation period (in vivo):
1h, 24h, 48h, 72 h
Number of animals or in vitro replicates:
6
Details on study design:
0.1 g of the test material was placed into the conjunctival sac of the left eye while the right eye served as a control. Readings of ocular reactions were made 1h, 24h, 48h and 72h after treatment. Beside this the eyes were examined for potential eye lesions 24h and 72h p.a. by means of 1 % fluorescein dilution (1 drop/eye).

Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Grillocin PY 88 is not irritating to eyes.
Executive summary:

The test substance is a fine white powder. The potential to cause damage to the conjunctivae, iris and cornea was assessed by single application of the test substance into the lower conjunctival sac of the eyes of six rabbits, strain New Zealand White, according to the OECD Guideline for the Testing of Chemicals No. 405 “Acute Eye Irritation/Corrosion”. Ocular reactions were assessed 1, 24, 48, and 72 hours after application of the test substance. At 24 h and 72 h p.a. the eyes of all animals were further examined with fluorescein to look for cornea damage. All six animals showed slight to moderate ocular reaction 1h and 24h after application of the test substance . 48h after application all animals were without any sign of ocular irritation. Cornea and iris remained uneffected. The test substance is valuated as not irritating to eyes.
