Description |
Colorless, slightly viscous liquid; [HSDB] |
Sources/Uses |
Used primarily as a stabilizer of vinyl polymers; [ACGIH] |
Comments |
Mice and rats exposed to high concentrations develop pneumonitis and emphysema; Rabbits show skin irritation and reversible corneal burns after skin and eye exposure; [ACGIH] In lethal inhalation studies of rodents, pulmonary edema was usually the cause of death; There is no experimental data, but glycidol, an epoxide, should be considered a potential skin and respiratory sensitizer; [HSDB] |

Excerpts from Documentation for IDLHs |
Other animal data: It has been reported that rats exposed repeatedly to 400 ppm for 7 hours per day, 5 days a week for 10 weeks showed no evidence of cumulative toxicity, only very slight irritation of the eyes, and slight lacrimation and respiratory distress following the first few exposures [Hine et al. 1956].
Human data: None relevant for use in determining the revised IDLH |
