Applicant's summary and conclusion
- Interpretation of results:
- Category 3 (mild irritant) based on GHS criteria
- Remarks:
- Migrated information
- Conclusions:
- Sodium Perborate Monohydrate was mild irritating to the skin of rabbits according to the GHS classification system (Category 3, reversible effects in dermal tissue, Draize score >= 1.5 to < 2.3).
- Executive summary:
In a skin irritation/corrosion study according to OECD 404, three rabbits were dosed with Sodium Perborate Monohydrate under semi-occlusive conditions to the intact clipped skin at a dose level of 0.5 g/animal.
After an exposure period of 4 hours, patches were removed and sites washed. Dermal reactions were scored according to Draize at 1, 24, 48 and 72 hours after patch removal.
Erythema, slight at 30 min and 24 and 48 hours, was absent to slight after 72 hours. Oedema was absent to slight at all observation periods.
According to GHS, the test item can be classified as mild irritant (Category 3).
