Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Remarks:
- Migrated information
- Conclusions:
- The substance produced a primary irritation index of 0.0 and was classified as a non-irritant according to Draize classification scheme.
- Executive summary:
An in vivo study was performed to assess the irritancy potential of the substance to the skin of New Zealand White rabbit according to OECD TG 404 (Acute Dermal Irritation/Corrosion). A single 4 -hour, semi-occluded application of the substance to the intact skin of 3 rabbits produced no evidence of skin irritation. Three-minute and 1 -hour semi-occluded applications of the substance to the intact skin of 1 rabbit produced no evidence of skin irritation. The substance produced a primary irritation index of 0.0 and therefore classified as non-irritant to rabbit skin according to the Draize classification scheme.
