- Irritant / corrosive response data:
- IRRITATION
The test item showed irritation when applied on the rabbit eye mucosa.
COLORATION
No discoloration of the cornea and conjunctivae related to effects of the test article was observed in the rabbits during the treatment and observation intervals.
CORROSION
No corrosion of the cornea was observed at each of the measuring intervals. - Other effects:
- BODY WEIGHTS
The body weight gain of all rabbits was similar.
TOXIC SYMPTOMS
No acute toxicological signs were observed in the animals during the test period, and no mortality occurred.
NECROPSY
Due to the results obtained, no macroscopic organ examination was indicated.
Applicant's summary and conclusion
- Interpretation of results:
- irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the conditions of this experiment the test item was found to cause a moderate irritation when applied to the rabbit eye mucosa. No discoloration of the cornea and conjunctivae which could be related to effects of the test article was observed. No corrosion was observed at each of the measuring intervals.
The maximum mean total score was found to be: 4.9 (unrinsed eyes). The body weight gain of all rabbits was similar. No systemic effects were observed. - Executive summary:
A study according to OECD Guideline 405 (Acute Eye Irritation / Corrosion) was carried out. A group of 3 rabbits (New Zealand White) were administered 0.1 g of test item into one eye. The untreated eye served as control. Treated eyes were not washed following application. Animals were observed 1, 24, 48 and 72 hours as well as 7 days after treatment.
Under the conditions of this experiment, the test item was found to cause moderate irritation when applied to the rabbit eye mucosa. No discoloration of the cornea and conjunctivae which could be related to effects of the test article was observed. No corrosion was observed at each of the measuring intervals. The body weight gain of all rabbits was similar. No systemic effects were observed.
