Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The acute dermal LD50 in rabbits for Tetrabromobisphenol-A is greater than 2 g/kg bw
- Executive summary:
In an acute dermal toxicity study conducted to GLP, tetrabromobisphenol-A, Lot #R6/PD2, was applied at 2 g/kg of body weight to ten rabbits (five males and five females). The test article was administered directly on the skin which was abraded within two hours prior to application. All animals survived the 2 g/kg dose for the fourteen day observation period. Slight erythema and edema were observed in one of the ten rabbits on Day 1. No other signs were visible during the fourteen day study. Terminal necropsy revealed no visible lesions in any rabbits on study.
The acute dermal LD50 in rabbits for Tetrabromobisphenol-A is greater than 2 g/kg bw.
