- Executive summary:
In acute dermal toxicity study,Guinea pigswere exposed with 3-aminopropylmethylamine in the concentration of84.4 to 844 mg/kgonClipped backs of abdomen by occlusive wrappingfor 24 hours.Two animals were died after 24 hours. Necroses and hemorrhage were observed in treated Guinea pigs. Severe erythema was observed in treated Guinea pigs. No skin sensitization was observed in treated Guinea pigs.Therefore,LD50 was considered to be>844 mg/kgwhen Guinea pigs were exposed with3-aminopropylmethylamineonClipped backs of abdomen by occlusive wrappingfor 24 hours.
