Chemical Safety
1357 DIETHYLENE GLYCOL DIMETHYL ETHER
IMPORTANT DATA
Physical State; Appearance Routes of exposure
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR. The substance can be absorbed into the body by inhalation of its
vapour, by ingestion and through the skin.
Chemical dangers
Inhalation risk
The substance can presumably form explosive peroxides. Reacts
violently with strong oxidants. A harmful contamination of the air can be reached rather quickly
on evaporation of this substance at 20/C.
Occupational exposure limits
Effects of short-term exposure
TLV not established.
MAK: 5 ppm, 28 mg/m 3; skin absorption (H); Peak limitation The substance is mildly irritating to the eyes, the skin and the
category: II(8); Pregnancy risk group: B; (DFG 2004). respiratory tract.
Effects of long-term or repeated exposure
Animal tests show that this substance possibly causes toxicity to
human reproduction or development.
PHYSICAL PROPERTIES
Boiling point: 162/C Relative density of the vapour/air-mixture at 20/C (air = 1): 1.01
Melting point: -68/C Flash point: 51/C c.c.
Relative density (water = 1): 0.95 Auto-ignition temperature: 190/C
Solubility in water: miscible Explosive limits, vol% in air: 1.5-17.4
Vapour pressure, kPa at 20/C: 0.33 Octanol/water partition coefficient as log Pow: -0.36
