CAS number: 110805
NIOSH REL: 0.5 ppm (1.8 mg/m3) TWA [skin]
Current OSHA PEL: 200 ppm (740 mg/m3) TWA [skin]
1989 OSHA PEL: Same as current PEL
1993-1994 ACGIH TLV: 5 ppm (18 mg/m3) TWA [skin]
Description of Substance: Colorless liquid with a sweet, pleasant, etherlike odor.
LEL(@200 F): 1.7% (10% LEL(@200 F), 1,700 ppm)
Original (SCP) IDLH: 6,000 ppm
Basis for original (SCP) IDLH: The chosen IDLH is based on the statement by AIHA  that investigators concluded from animal experiments that substantially saturated atmospheres (6,000 ppm) at ordinary room temperatures will not produce serious injury in 1 hour [Waite et al. 1930].
Short-term exposure guidelines: None developed
ACUTE TOXICITY DATA
Lethal concentration data:
Lethal dose data:
Other animal data: Some investigators have stated that at ordinary room temperatures substantially saturated atmospheres (i.e., about 6,000 ppm) will not produce serious injury in 1 hour [Waite et al. 1930].
Human data: Volunteers with some work experience reported that odor levels of 125 ppm were noticeable and that the odor level that would be intolerable was greater than 255 ppm [Clayton and Clayton 1982].
|Revised IDLH: 500 ppm
Basis for revised IDLH: The revised IDLH for 2ethoxyethanol is 500 ppm based on acute inhalation toxicity data in animals [NPIRI 1974; Werner et al. 1943]. This may be a conservative value due to the lack of relevant acute toxicity data for workers exposed to concentrations above 255 ppm.
