The subchronic inhalation toxicology of ethylene glycol monoethyl ether (EGEE) was evaluated in rats and rabbits using a week exposure regimen. Groups of 20 rabbits (10 M, 10 F) and 30 rats (15 M, 15 F) were exposed to a vapor of 25 ppm, ppm, or ppm, 6 hr/day, 5 days/week.
The control groups received air only.

No mortality or abnormal clinical signs in any group were observed. Body weight gains were decreased with a tendency for reduction of feed intake in the % and above female and 5% male by: 3. Subchronic inhalation toxicity studies are primarily used to derive regulatory concentrations for assessing worker risk in occupation settings.
They are also used to assess human residential, transportation, and environmental risk. This guideline enables the characterization of adverse effects. The toxicity database for repeated inhalation exposure in laboratory animals consists of two week studies — one in rats (NTP, c) and one in mice (NTP, d).
