Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The acute dermal median lethal dose (LD50) of the test material in the Sprague Dawley CD strain rat was found to be greater than 2000 mg/kg bodyweight. The test material does not meet the criteria for classification according to EU classification system.
- Executive summary:
Introduction. The study was performed to assess the acute dermal toxicity of the test material in the Sprague‑Dawley CD strain rat. The method was designed to meet the requirements of the following:
§ OECD Guidelines for the Testing of Chemicals No. 402 “Acute Dermal Toxicity” (adopted)
§ Method B3 Acute Toxicity (Dermal) of Commission Directive 92/69/EEC
Method. A group of ten animals (five males and five females) was given a single, 24-hour, semi‑occluded dermal application of the test material to intact skin at a dose level of 2000 mg/kg bodyweight. Clinical signs and bodyweight development were monitored during the study. All animals were subjected to gross necropsy.
Mortality. There were no deaths.
Clinical Observations. There were no signs of systemic toxicity.
Dermal Irritation. Well-defined erythema was noted at the treatment sites of all animals. Other signs of dermal irritation noted were crust formation, small superficial scattered scabs and superficial cracking of the epidermis. Treatment sites appeared normal two to thirteen days after dosing.
Bodyweight. All animals showed expected gains in bodyweight over the study period.
Necropsy. No abnormalities were noted at necropsy.
Conclusion. The acute dermal median lethal dose (LD50) of the test material in the Sprague‑Dawley CD strain rat was found to be greater than 2000 mg/kg bodyweight. The test material does not meet the criteria for classification according to EU classification system.
