Monoethylene glycol is a clear, colorless syrupy liquid. The primary hazard is the threat to the environment. Urgent steps must be taken to limit its spread to the environment. Because it is liquid, it can easily penetrate the soil and contaminate groundwater and nearby streams. Ethylene glycol is used to make antifreeze and defrosting solutions for cars, airplanes and boats. It is also used in hydraulic brake fluids and inks used in stamp pads, ballpoint pens and printing presses.

Application

» This substance is used in the following products: textile treatment products and dyes, washing and cleaning products, coating products, inks and toners, non-metallic surface treatment products, leather treatment products, lacquers and waxes, adhesives and sealants, polymers, heat transfer fluids, hydraulic fluids, antifreeze products and biocides (eg disinfectants, pest control products).
» Used in machine wash fluids/detergents, automotive care products, paints, coatings or adhesives, fragrances, air fresheners, coolants in refrigerators, oil-based electric heaters, hydraulic fluids in automotive suspension, lubricants in engine oil and brake fluids.
