Acute oral toxicity was assessed in a limit test according to OECD 401 (Hüls, 1995). The LD 50 was above 2000 mg/kg bw. Acute toxicity by inhalation was assessed in an acute inhalation toxicity study similar to OECD 403 (Hazleton, 1965). An LC 50 of 14.2 mg/l was concluded. The dermal route was assessed in a limit test according to OECD 402 (Hüls, 1996). The LD50 was above 2000 mg/kg bw.
Acute toxicity tests conducted in Wistar rats are available for all
three routes. All studies are conducted similar or according to OECD
guidelines. Both LD50 values for the oral and the dermal route were
above a limit dose of 2000 mg/kg bw. An LC50 value for toxicity by
inhalation could be derived (14.2 mg/l ).
An LC 50 of 14.2 mg/l has been concluded for
3,3,5-trimethylcyclohexanone. According to Regulation (EC) No 1272/2008
it has not been classified.
LD 50 values for oral and dermal exposure are above the limit dose
of 2000 mg/kg bw. A classification is not warranted for these routes.
