study was conducted to evaluate the acute inhalation toxicity of the
test substance (trimethylolpropane triacrylate - TMPTA) in rats.
rats/sex were exposed
to the vapor of the test substance (trimethylolpropane triacrylate -
TMPTA) at a single concentration of 0.55 mg/L air (nominal) for 6 h
followed by and observation period of 14 days. Body weight was measured
during the observation period and necropsy was performed at the end of
were no untoward reactions noted during exposure or during the 14 day
observation period. The average body weight gains were within the normal
limits. Necropsy, performed on all rats at the end of the observation
period, did not reveal any gross pathologic alterations.
conclusion, the single median lethal inhalation (LC50) of the test
substance (trimethylolpropane triacrylate - TMPTA) was determined to be
greater than 0.55 mg/L after 6 h exposure in rats.
