Composition / Information on Ingredients

Chemical Name: Tetraethylene Glycol Methyl Ether
Concentration Range: 98–100%
CAS Number: 2374-38-3
Impurities: Trace polyether byproducts under 2%
Additives: None identified

First Aid Measures

Inhalation: Move to fresh air, seek medical advice if symptoms (cough, headache, short breath) persist
Skin Contact: Remove contaminated clothing, rinse skin with plenty of water, wash thoroughly with soap
Eye Contact: Rinse cautiously with clean water for at least 15 minutes, lift eyelids occasionally, contact medical services if redness or pain remains
Ingestion: Rinse mouth, never induce vomiting, seek professional medical help right away

Fire-Fighting Measures

Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical extinguishers, carbon dioxide
Unsuitable Media: Direct water streams, may spread the liquid
Fire Hazards: Moderate fire risk at high temperatures, forms toxic fumes (carbon oxides)
Protective Equipment: Firefighters use self-contained breathing gear, full protective clothing
Specific Methods: Cool fire-exposed containers, prevent spill water from entering drains

Accidental Release Measures

Personal Precautions: Use chemical splash goggles, chemical-resistant gloves, good ventilation
Leak Procedures: Stop source if safe, contain with sand or absorbent, avoid inhaling vapors
Clean-up Methods: Collect with non-sparking tools, place in suitable labeled containers
Environmental Precautions: Keep substance out of drains, rivers, and groundwater, inform authorities if large volume escapes

Handling and Storage

Handling: Never eat or smoke during use, minimize skin and eye contact, wear chemical-resistant personal protection, use in a ventilated spot
Storage: Keep in tight containers, store cool and out of sunlight, separate from acids and oxidizers, avoid freezing
Incompatibilities: Strong acids, strong oxidizing agents, avoid storing near open flames or sources of heat
Special Procedures: Regularly check for leaks and container damage, keep label information visible

Exposure Controls and Personal Protection

Control Parameters: No established occupational exposure limit; follow local rules
Engineering Controls: Use fume extraction or mechanical ventilation for large scale use
Personal Protection: Work glasses with side shields, gloves resistant to organic solvents (e.g. nitrile), splash aprons, emergency eyewash stations
Respiratory Protection: Mask or respirator (organic vapor cartridge) for splashes, spills, or poor ventilation
Hygiene Measures: Wash hands before breaks, after use, keep work clothes separate from personal clothing

Physical and Chemical Properties

Appearance: Clear, colorless to pale yellow liquid
Odor: Mild ether-like
pH (neat): Not relevant
Melting/Freezing Point: -20°C to -10°C
Boiling Point: 275–285°C at atmospheric pressure
Flash Point: 140–150°C (closed cup)
Vapor Pressure: Very low at room temperature
Solubility: Mixes well with water and many solvents
Viscosity: Slightly higher than water
Density: Around 1.04 g/cm³
Partition Coefficient: Log Pow estimated near -1

Stability and Reactivity

Chemical Stability: Remains stable under recommended storage, highly stable at room temperature away from incompatible substances
Reactivity: May react with strong oxidizers or acids, can form flammable vapors at high temps
Conditions to Avoid: Open flames, high temperature, strong acids
Hazardous Decomposition: Thermal breakdown creates carbon monoxide, carbon dioxide, trace ether gases
Polymerization: No self-polymerizing tendencies noted

Toxicological Information

Routes of Entry: Skin, inhalation, ingestion
Acute Toxicity: Low oral and dermal toxicity; LD50 (rat, oral) estimated above 2000 mg/kg
Chronic Effects: No relevant evidence for repeated dose hazard, not mutagenic, not a reproductive toxin so far
Symptoms of Exposure: Eye or skin redness, transient dizziness or nausea from inhaling vapors
Note: Prolonged exposure without protective gear may worsen irritation symptoms

Ecological Information

Aquatic Toxicity: Expected to be low; LC50 (fish, 96hrs): >100 mg/L
Persistence/Degradability: Biodegradable, breaks down readily in aerobic environments
Bioaccumulation: Not expected, low partition coefficient
Mobility in Soil: Moves readily through soil and water due to high solubility
Environmental Impact: Large spill possible local water contamination, dilute rapidly

Disposal Considerations

Waste Treatment: Absorb spilled material with non-flammable binders, incinerate in licensed chemical disposal
Contaminated Packaging: Triple rinse, treat as hazardous waste
Precautions: Never pour into drains, do not use landfill without regulations
Disposal Regulations: Follow local rules on chemical solvent waste, collect certificates for destruction or recycling
