Signal Word: Warning
Hazard Statements: May cause eye irritation, potential for mild skin irritation through repeated exposure, slight headache or nausea on inhalation of high vapor concentrations
Precautionary Statements: Avoid breathing vapors or mists, minimize skin and eye contact, wash contaminated areas after handling, use recommended protective equipment
Label Pictograms: Usually displays the exclamation mark GHS symbol indicating health hazard by irritation
Chemical Name: Diethylene Glycol Monoethyl Ether
Concentration: Often above 99% unless mixed
Impurities: Trace amounts of water, glycol ethers, stabilizers as received from supplier
Other Ingredients: None specified in pure product samples, mixtures combined with water or compatible organics in formulated products
Inhalation: Move exposed person to fresh air promptly, seek medical attention if symptoms like coughing or dizziness persist
Skin Contact: Remove soiled clothing, rinse affected skin with water for at least fifteen minutes, seek care for irritation
Eye Contact: Flush eyes gently under running water for at least fifteen minutes, do not rub, contact a physician if pain or redness lasts
Ingestion: Do not force vomiting, rinse mouth, obtain immediate medical attention, especially if large amounts swallowed or symptoms develop fast
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, alcohol-resistant foam, water spray recommended to cool containers under fire stress
Specific Hazards: Container rupture from pressure buildup, formation of toxic decomposition vapors such as carbon monoxide under heavy fire
Protective Equipment: Use standard self-contained breathing apparatus, flame-resistant suit, keep upwind of smoke or vapor
Advice for Firefighters: Evacuate area, prevent runoff from entering drains or watercourses, use cooling sprays to maintain container integrity
Personal Precautions: Remove ignition sources, ventilate area, avoid inhalation of vapors or direct contact
Protective Equipment: Chemical-resistant gloves, goggles, suitable apron, and in high-volume spills, use of organic vapor respirators
Environmental Precautions: Prevent product from reaching surface water, sewers, soil, apply absorbent materials like sand for small spills and diking for larger releases
Cleanup Methods: Soak up on inert material, transfer to labeled disposal drums, decontaminate area with detergent and water, dispose through licensed facility
Handling: Work in ventilated area, keep containers sealed when not in use, minimize splashes and aerosolization, avoid exposure by ingestion and skin
Storage: Store in original, tightly closed containers away from heat sources, sunlight, incompatible chemicals like strong acids or oxidizers, keep away from food and drink stock
Special Instructions: Ensure labeling stays readable, segregate from combustibles and out of reach from untrained personnel, check containers regularly for leaks
Engineering Controls: Fume hoods, local exhaust recommended in high-use or poorly-ventilated settings
Occupational Exposure Limits: Many countries set TWA (time-weighted average) limits between 25–50 ppm; check local regulation
Personal Protective Equipment: Splash-resistant goggles, chemical-resistant gloves, laboratory coat or apron, closed-toe shoes, optional face shield for splatter risks
Respiratory Protection: Approved organic vapor masks or air-purifying respirators in circumstances of inadequate ventilation
Hygiene Practices: Wash thoroughly before breaks and after tasks, keep contaminated workwear separate from clean clothing
Appearance: Clear, colorless liquid
Odor: Mild, ether-like, sometimes sweet
Melting Point: -80°C
Boiling Point: 196–202°C
Flash Point: 96°C (closed cup)
Vapor Pressure: Less than 0.1 mm Hg at 25°C
Relative Density: 0.99 g/cm³ at 20°C
Solubility: Miscible with water and a wide variety of organic solvents
Viscosity: About 4 mPa·s at room temperature
pH: Not applicable in pure form
Chemical Stability: Stable at room temperature away from direct sunlight and incompatible chemicals
Conditions to Avoid: High heat, open flame, static discharge, moisture in storage containers
Materials to Avoid: Strong oxidizing agents, acids, alkali metals, reactive halides
Hazardous Decomposition Products: Carbon oxides (CO, CO₂) from fire or extreme decomposition, possible ether-volatile fragments
Routes of Exposure: Skin, inhalation, ingestion, eye contact
Acute Effects: Mild eye or skin irritation, headaches, transient nausea, coughing from vapor at higher levels
Long-Term Effects: Animal studies show little chronic toxicity but long-term in high amounts might impact kidney or liver, based on related glycol ethers
Sensitization: Not known to cause allergic response under normal workplace exposure
Carcinogenicity: Not classified as carcinogenic by IARC, EPA, or NTP
Environmental Fate: Biodegrades relatively quickly in natural waters, less likely to persist long term
Aquatic Toxicity: Low toxicity to fish and invertebrates, but may contribute to oxygen depletion in water if a major spill occurs
Bioaccumulation Potential: No significant bioaccumulation anticipated
Other Effects: Large volume spills may disrupt local microbial populations temporarily, wastewater treatment plants can generally break down residues over time
Waste Disposal: Collect and label for hazardous waste pickup, use incineration or authorized solvents processor
Container Disposal: Rinse containers, avoid landfill for large cleanouts, send for recycling or appropriate chemical disposal site
Precautions: Review local, state, and federal disposal requirements, never flush to drains, consult environmental manager for on-site protocols
UN Number: Not regulated for road (ADR/RID), air (ICAO/IATA), or sea (IMDG) transport under usual concentrations
Proper Shipping Name: Not classified as hazardous under international shipping guidelines
Packing Group: None assigned for pure chemical
Transport Hazard Class: Not regulated, no hazard label required
Special Precautions: Ensure closure integrity and upright placement, prevent leaks in transit, refer to shipping documentation for mixed loads
TSCA Inventory: Listed as existing in the United States chemical inventory
REACH Status: Registered for manufacture/import in the European Union above 1 tonne per year
SARA Title III: Does not appear as Section 313-listed chemical
California Proposition 65: Not identified for reproductive or cancer risk listing
Other Local Regulations: Regional workplace controls may require routine air sampling or health surveillance, safety data availability for users, and regular container audits in many industrial or laboratory settings
