Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Under the conditions of the study, the test substance is considerd to be only slightly irritating to eyes of rabbit.
Executive summary:

A study was conducted to determine the acute eye irritation potential of undiluted 'fatty acids, castor-oil, hydrogenated' in accordance with OECD Guideline 405 and Council Directive 84/449/EEC, L 251.

The test substance was applied to the right eye of 3 rabbits at a single dose of 0.1 ml volume for 24 h. The left eye served as a control.

Symptoms were reported for a period of 7 d after application. All observations were assessed according to the Council Directive 84/449/EEC.

Slight to strong erythema and slight chemosis were observed. The reactions disappeared completely 14 d after application. The treated eyes were without any lesions on their cornea and no symptoms on the iris were observed at anytime during the test.

Under the conditions of the study, the test substance is considerd as only slightly irritating to eyes of rabbit.
