key study
Study period:
1971
Reliability:

Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
The study is performed in male animals only, with a +- 50% active ingredient formulation, and not under GLP compliance. Similar studies wiht different formulations provided consistent results in terms of active ingredient for the acute oral toxicity studies, therefore this study is also considered to be adequate, reliable and relevant.

Applicant's summary and conclusion

Interpretation of results:
other: irritating
Remarks:
FHSA definition
Conclusions:
The test item containing +-50% active ingredient was irritating to the rabbit eye (an irritant by FHSA definition). 6 of 6 eyes were positive for corneal opacity; 3 of 6 had iritis.
Executive summary:

6 Male albino rabbits underwent an eye irritation test with 0.1 mL test item containing +-50% active ingredient. According to FHSA procedure. Scoring according to Draize et al. (1944) demonstrated mean 24 -48h score of 20.6/80 for cornea, 1.9/10 for iris and 4.1/20 for conjuctiva irritation, therefore the substance was concluded to be irritating to the rabbit eye (by FHSA definition), with 6 of 6 eyes positive for corneal opacity and 3 of 6 with iritis.
