Chemical Identity: Triethylene Glycol Methyl Ether Borate
Synonyms: Not widely recognized under alternative names in common industry literature
Formula: Mixture; no single molecular formula due to complexation
Physical State: Liquid, likely clear or pale yellow, with a mild odor reminiscent of glycol ethers, viscosity higher than water, often used where unique solvency is needed
Common Uses: Find this compound in specialty industrial applications, including lubrication, solvent blends, and specialty fluid systems; interest comes from its ability to bind water and provide unique solvency
Health Effects: Extended skin contact may cause dryness or irritation. Eyes may feel irritation or stinging with splashes. Short-term fumes in poorly ventilated areas can bring headaches or respiratory discomfort. Sniffing or ingesting can irritate mucous membranes and lead to nausea.
Flammability: Medium risk: will burn if exposed to strong ignition sources, but not explosively. Vapors heavier than air, posing risks in confined spaces.
Environmental Concerns: Aquatic organisms might be harmed if spills reach surface water. Biodegradation tends to be moderate, but not rapid, so persistence in soils is a worry.
Warning Labels: Eye and skin irritant, harmful if inhaled or swallowed. Not classified as a carcinogen by IARC, NTP, or OSHA, but data gaps exist.
Main Components: Triethylene glycol methyl ether, boric acid derivatives
Minor Admixtures: Possible contaminants stemming from synthesis, such as glycol by-products
Chemical Family: Glycol ethers combined with inorganic borate
Ingredient Clarity: Industry literature cites proprietary blending, leaving exact amounts imprecise; ratio of glycol ether to borate often tailored for desired property
Eye Contact: Rinse eyes gently with clean water for several minutes, keep eyelids apart, do not rub; contact a physician if irritation persists. Removing contacts helps wash out the chemical.
Skin Exposure: Wash exposed skin with lukewarm water and mild soap; for rashes or persistent irritation, consult health staff.
Inhalation: Move to fresh air; loosen tight clothing. If coughing or dizziness occurs, medical attention recommended.
Ingestion: Do not induce vomiting. Rinse mouth, drink plenty of water, seek immediate care for larger exposures. Bring label or sample, if possible.
Extinguishing Media: CO2, dry chemical, or foam preferred. Water can help cool surfaces but may spread spillage.
Specific Hazards: Burning may release toxic fumes—carbon oxides and boron compounds. Closed tanks may rupture if heated.
Protective Equipment: Full protective gear: boots, gloves, chemical suit, eye shield, and, in confined spaces, a self-contained breathing apparatus.
Firefighting Tactics: Remove containers from fire area if safe; keep them cool with water spray to prevent explosion.
Personal Precautions: Evacuate unnecessary personnel, ventilate area, avoid inhaling vapors, and wear gloves or goggles for cleanup. Prevent skin contact and inhalation.
Environmental Precautions: Block off storm drains, avoid runoff to soil or waterways.
Containment Methods: Use absorbent materials—vermiculite, sand, or commercial pads. Collect spillage, place in labeled, sealed drums for later disposal.
Handling Habits: Keep containers well sealed, avoid splashing during transfer. Wear protective gloves and goggles, avoid open flames or sources of ignition.
Storage Conditions: Store in a cool, dry, well-ventilated building. Place drums away from strong acids, oxidizers, and metals that could react with borate. Inspect containers for leaks or degradation periodically.
Labeling: Use clear hazard signage, preventing routine exposure or accidental mixing with foodstuffs.
Ventilation: Local exhaust ventilation keeps vapor concentrations below recommended limits.
Personal Protective Equipment: Nitrile gloves resist glycol ethers well; chemical splash goggles keep the compound out of the eyes. Respirators may become necessary where exposure exceeds recommended levels.
Work Practices: Remove contaminated clothing, wash thoroughly after handling. Keep food and drink away from chemical area, never eat or smoke during tasks.
Exposure Limits: OSHA does not provide a specific PEL for triethylene glycol methyl ether borate; glycol ethers sometimes compartmentalized by broader class limits, but extra caution advised due to lack of unified data.
Form: Viscous clear or pale yellow liquid
Odor: Mild, slightly ether-like
Boiling Range: Higher than water thanks to glycol ether backbone—often upwards of 250°C, depending on blend
Melting Point: Usually remains liquid at room temperature
Vapor Pressure: Low at ambient temperature relieves some inhalation risks; as temperature rises, risk increases
Solubility: Miscible with water and most polar organic solvents, reflecting root glycol ether characteristics; borate component can influence water compatibility
Density: Higher than water, typically in the range of 1.1–1.2 g/cm³
Stability: Remains stable under ordinary handling and storage; decomposition starts at high heat or open flame.
Reactive Materials: Avoid mixing with aluminum, zinc, magnesium, strong acids, or oxidizers; borate formation can bring unexpected chemistry.
Hazardous Decomposition: May create hazardous vapors—carbon monoxide, carbon dioxide, and boron oxides.
Routes of Exposure: Eyes and skin at the top of the risk list, inhalation risk low unless poorly ventilated. Repeated contact can dry skin or trigger mild dermatitis.
Acute Effects: Short-term exposure: eye/skin irritation, headaches, nausea if inhaled at high concentrations.
Chronic Effects: Not well documented; glycol ethers as a family have drawn scrutiny for effects on blood and reproduction, so extra care warranted.
Carcinogenicity: Not listed by major cancer authorities, but data is not conclusive.
Aquatic Toxicity: Likely to harm fish and small aquatic creatures at higher concentrations.
Soil Mobility: Tends to stay in water columns for a time; can leach in porous soils, breaking down at a moderate pace.
Degradation: Borate component slows full decomposition, but sunlight and bacteria eventually break down glycol ether backbone.
Bioaccumulation: Unlikely to seriously persist in living tissues, but periodic monitoring is sound practice, especially in sensitive environments.
Waste Disposal: Treat as hazardous chemical waste—collect using non-reactive containers, segregate from incompatible wastes.
Method: Send to chemical waste processor with approval for glycol ethers and borates. Never pour down the drain or sewer. Approved incineration or chemical recycling centers handle the job best.
Container Disposal: Empty drums need thorough triple-rinsing, puncturing, and clear hazard labeling before recycling or waste shipment.
Shipping Category: Classified as a regulated liquid in many regions, especially where spill to watercourses threatens wildlife or potable water.
Packing Group: Not classified as a high-hazard explosive, but local regulations could demand sturdy, leak-proof drums with appropriate danger markings, especially during export.
Storage in Transit: Keep cool, ventilated; avoid truck beds with unshielded heat or direct sun exposure.
Global Compliance: Many jurisdictions expect adherence to workplace labeling (OSHA GHS), workplace exposure monitoring, and spill response plans. EPA and state environmental agencies monitor glycol ether use near bodies of water. Borate controls more pressing in Europe, where environmental thresholds can be lower. Requirements shift year by year, so staying current with government notices keeps the operation in compliance.
Hazard Communication: Employers offer employee training, easy access to safety literature, and enforceable PPE use. Extra measures arise in countries that flag glycol ethers or borates as chemicals of concern.
