Comments

Central nervous system depression observed in animal studies; [ACGIH] An eye and respiratory tract irritant; Inhalation of high concentrations can cause CNS depression; [ICSC] See "Glycol ethers."

Exposure Assessment
Skin Designation (ACGIH)

Yes

TLV (ACGIH)

100 ppm

STEL (ACGIH)

150 ppm

PEL (OSHA)

100 ppm

50 ppm, mixture of isomers

IDLH (NIOSH)

600 ppm

Excerpts from Documentation for IDLHs

Concentrations between 300 and 400 ppm have been reported to be very disagreeable [Rowe et al. 1954]. Central nervous system impairment (undefined) occurred at 1,000 ppm in one of two subjects [Stewart et al. 1970]. . . .Concentrations above 5,000 ppm are unlikely to be encountered in the workplace because of the high boiling point and low vapor pressure of this substance.

Vapor Pressure

0.5 mm Hg

Odor Threshold Low

35 ppm

Explanatory Notes

Odor threshold from CHEMINFO; Flash point = 85 deg C;
