Chemical Safety
0551 PROPYLENE GLYCOL MONOMETHYL 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
or its aerosol, through the skin and by ingestion.
Chemical dangers
The substance can presumably form explosive peroxides. Reacts with Inhalation risk
strong oxidants, acid chlorides, acid anhydrides, aluminium and copper. A harmful contamination of the air will be reached rather slowly on
evaporation of this substance at 20/C.
Occupational exposure limits
TLV: 100 ppm; 369 mg/m3 (as TWA), 150 ppm; 553 mg/m3 (STEL) Effects of short-term exposure
(ACGIH 1997). The substance and the vapour (in high concentrations) irritates the eyes,
EU OEL: 100 ppm, 375 mg/m3 as TWA; 150 ppm, 568 mg/m3 as STEL; the skin and the respiratory tract. Exposure to very high concentrations
(skin) (EU 2000). may result in central nervous system depression.
Effects of long-term or repeated exposure
The liquid defats the skin.
PHYSICAL PROPERTIES
Boiling point: 120/C Relative density of the vapour/air-mixture at 20/C (air = 1): 1.03
Melting point: -96/C Flash point: 38/C
Relative density (water = 1): 0.92 Auto-ignition temperature: 270/C
Solubility in water: very good Explosive limits, vol% in air: 1.9-13.1
Vapour pressure, kPa at 20/C: 1.2
ENVIRONMENTAL DATA
NOTES
Commercial product may contain impurities which may alter toxic properties.
Check for peroxides prior to distillation; eliminate if found.
Dowanol 33 B, Dowanol PM, Dowtherm 209, Poly-Solv MPM Solvent, PolySolvent M, Propasol Solvent M, UCAR PM Solvent, Ucar Triol HG-170 are
trade names.
