Description of key information
The acute oral LD50 of N,N'-1,6-hexanediylbis(N-(2,2,6,6-tetramethyl-piperidin-4-yl)formamide was > 2200 mg/kg bw in rats; no mortatily, no clinical signs and no gross pathological findings were observed.
No mortality was observed in an acute aerosol inhalation toxicity study up to the highest concentration tested, which was 5000 mg/m³. Accelerated breathing during exposure. Reddish incrustated noses (day 1 of observation period). No gross pathological findings were observed. The LC50 was > 5000 mg/m³.
A test on acute dermal toxicity was not performed.
