Materials and methods

Principles of method if other than guideline:
Fifty µL of 3-isopropoxypropylamine were applied to the conjunctival sac of one eye in 2 animals. The animals were observed after 10 min, 1 and 3h on the day of treatment and up to 8 days afterwards. Findings were recorded daily. The eyes were not washed out after 24 hours.
GLP compliance:
no

Reversibility:
not reversible

Any other information on results incl. tables

The application of the test substance caused corrosion to the exposed eyes and therefor a precise evaluation of opacity, erythema, chemosis and iritis was not possible. Major finding: irreversible corrosion of the eyes.

Applicant's summary and conclusion

Interpretation of results:
Category 1 (irreversible effects on the eye)
Remarks:
Migrated information Criteria used for interpretation of results: EU
Executive summary:

Fifty µL of 3-isopropoxypropylamine were applied to the conjunctival sac of one eye in 2 animals (BASF, 1970d). The animals were observed after 10 min, 1 and 3h on the day of treatment and up to 8 days afterwards. Findings were recorded daily. The eyes were not washed out after 24 hours. The report describes findings after 1 and 24 hours and at the end of the observation period. For final evaluation, the findings after 48 and 72 hours from the raw data were taken into account. The application of 3-isopropoxypropylamine caused corrosion to the exposed eyes and therefore a precise evaluation of opacity, erythema, chemosis and iritis was not possible.
