- Conclusions:
- The acute dermal LD50 value was considered to be >5000 mg/kg bw, when rabbits were treated with 3,3-Dimethyl-8,9-dinorbornan-2-one (CAS no: 1195-79-5) by dermal application.
- Executive summary:
Acute Dermal toxicity study of3,3-Dimethyl-8,9-dinorbornan-2-one (CAS no: 1195-79-5) was conducted in rabbits at the concentration of 5000 mg/kg bw. No mortality was observed at 5000 mg/kg bw. Therefore, LD50 value was considered to be >5000 mg/kg bw, when rabbits were treated with 3,3-Dimethyl-8,9-dinorbornan-2-one (CAS no: 1195-79-5) by dermal application.
