- unchanged (no vehicle)
- Controls:
- not required
- Amount / concentration applied:
- 0.1 g of the substance to be tested were installed into one eye of each animal.
- Duration of treatment / exposure:
- 7 days
- Observation period (in vivo):
- Ocular lesions were read 1h, 2h, 4h, 8h, 24h, 2d, 3d, 4d, 5d, 6d, 7d after the administration of the test substance
- Number of animals or in vitro replicates:

Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: other: ETAD SUBCOMMITTEE FOR TOXICOLOGY
- Conclusions:
- The substance Atrazine technical was treated undiluted (as powder) in a primary irritation test in rabbit eyes.
under the described conditions of the experiment it was found:
1. The conjunctival irritations of the first 12 hours disappeared after 24 hours.
2. according to the code of evaluation by ETAD SUBCOMMITTEE FOR TOXICOLOGY the substance is valuated as "non irritant"
