Oral: LD50> 2000 mg/kg b.w. for rat (OECD 423)
Dermal: LD50> 2000 mg/kg b.w. for rat (OECD 402, 24h exposure)
Inhalation: LC50= 3110 mg/m³ for rat, with the analogous read-across
substance NA-70 (OECD 403, 4 h exposure)

Atmosphere Concentration (mg/L)
In both, the acute oral and
the acute dermal toxicity studies with NA-11, all animals survived the
limit dose of 2000 mg/kg b.w. Therefore, classification for acute oral
or dermal toxicity is not required [REGULATION (EC) 1272/2008].
to the result of the acute inhalation toxicity study NA - 11 has to be
classified as acute toxic category 4 (Regulation (EC) 1272/2008).
