Applicant's summary and conclusion

Interpretation of results:

highly irritating

Remarks:

Migrated information

Conclusions:

Sodium percarbonate was classified as highly irritating to the eye.

Executive summary:

The eye irritation potential of sodium percarbonate was tested in one male New Zealand White rabbit according to the OECD Guideline No 405 and to GLP. 100 mg of undiluted test material was instilled into the right eye of the animal and reaction was observed and scored following the Draize method after 1 and 5 hours.

The total maximum irritation score after 1 hour was 59 and after 5 hours was 61, and the test was stopped after 5 hours without a reversibility phase. Thus, sodium percarbonate was classified as highly irritating to the eye.
