Product Name: Polyethylene Glycol Dimethyl Ether
Chemical Formula: C6H14O3, (for PEG DME 250, for example)
Synonyms: Dimethyl polyethyleneglycol, DMPEG
CAS Number: 6423-82-5
Recommended Use: Solvent for chemical reactions, cleaning agent, electrolyte in batteries
Supplier Details: Company address, phone, and emergency contact information included on the actual container, always check the label.
GHS Classification: Green circle hazard, generally considered low flammability and toxicity. Not classed as a dangerous substance under most regulatory frameworks, though heavy exposure puts eyes and respiratory tract at risk.
Hazard Statements: Causes mild irritation to skin and eyes, prolonged inhalation might bother sensitive users, vapor in high concentrations can cause drowsiness or headache, ingestion in large amounts could upset the stomach and even depress the central nervous system if not treated on time.
Signal Word: Warning
Pictograms: Exclamation mark
Precautionary Statements: Use personal protection, don’t smoke or eat while working, wash up well after handling.
Chemical Name: Polyethylene glycol dimethyl ether
Purity: Usually above 99% for lab grade
Other Components: Water traces possible, small impurities from production
Impurities: None dangerous at usual levels, hazardous impurities might show up from decomposition or bad storage
EC No: 229-194-7
Inhalation: Move to fresh air, keep the person calm, seek medical advice if discomfort or coughing lasts.
Skin Contact: Wash skin well with soap and water, remove tainted clothing, don’t use harsh cleaning agents.
Eye Contact: Rinse eyes with clean water for at least 10-15 minutes, hold eyelids open, get checked by a doctor if burning or redness sticks around.
Ingestion: Rinse mouth with clean water, drink some water to flush the system, avoid vomiting unless told to by a professional. Medical help shows best results if something feels wrong.
Suitable Extinguishing Media: Water spray, alcohol-resistant foam, dry powder, or carbon dioxide work against most fires here.
Specific Hazards: Not the easiest to ignite, but if it catches, it burns clean and produces carbon monoxide, carbon dioxide, maybe some other organics if material’s old.
Protective Equipment: Full gear: self-contained breathing, heavy gloves, chemical splash suit if big spill’s burning.
Additional Advice: Cool containers with water if caught in the blaze, keep folks out of the smoke downwind, avoid runoff into drains.
Personal Precautions: Get good airflow, keep skin covered, safety specs over the eyes, gloves for cleanup.
Environmental Precautions: Do not dump into storm drains or groundwater. If big spill happens, cordon off and scoop up as much as possible before mopping the floor.
Cleanup Methods: Soak up with sand or other absorbents, then shovel into drum with cover. Rinse after using suitable cleaner.
Handling: Avoid direct contact or breathing the vapor too long, wear gloves and goggles, don’t get it on your shoes. Keep containers tight with proper labeling.
Storage Conditions: Store in closed drum in cool, ventilated space, keep away from acid or oxidizer storage areas, look out for leaks.
Storage Temperature: Ambient, don’t freeze or cook above 40°C—this damages the material.
Incompatible Materials: Strong oxidizers, acids, or alkali metals break it down, store away from them.
Engineering Controls: Fans or hoods for regular work, local exhaust a must for large jobs.
Exposure Limits: No strict OSHA limits, keep below 10 mg/m³ if possible to avoid irritation.
Personal Protection: Wear gloves (nitrile or rubber), goggles or shield where splash likely, lab coat or apron. Change clothes after big splash.
Respiratory Protection: Mask with organic vapor cartridge for long exposure or if vapor builds up.
Hygiene Measures: Wash hands well after use, never eat, drink, or smoke in the work area.
Appearance: Clear, colorless liquid with little odor
Odor: Faint, sweetish
pH: Neutral
Melting Point: Varies by type, commonly -10°C to -50°C
Boiling Point: Roughly 200°C
Flash Point: ~120°C (closed cup)
Vapor Pressure: Low
Solubility: Mixes in water, alcohol, acetone
Density: 0.95 - 1.00 g/cm³
Viscosity: Fairly thick for a solvent, depends on molecular weight
Chemical Stability: Stable on the shelf at room temperature, sealed.
Reactiveness: Reacts quickly with strong acid, oxidizer, alkali metals.
Hazardous Decomposition: Breaks down to carbon monoxide, carbon dioxide, and smaller ethers at high temps or open flames.
Other Risks: Strong heating in closed drum might rupture, so don’t overdo it.
Likely Exposure Routes: Skin, inhalation, accidental ingestion
Acute Effects: Eye irritation, mild coughing or throat soreness, nausea if swallowed
Chronic Effects: High and repeated exposure can dry out skin and bother nasal membranes
Toxicity Data: LD50 (oral, rat): over 5000 mg/kg—shows low hazard
Carcinogenicity: Not listed by ACGIH, IARC, NTP, or OSHA
Other Risks: Not linked to reproductive harm or genetic effects at normal levels
Ecotoxicity: Low risk to water life, but don’t dump large spills in ponds or streams
Persistence and Degradability: Breaks down in soil and water over weeks, not likely to bioaccumulate
Mobility: Floats in water, spreads but eventually disappears
Bioaccumulation: Not known to move up the food chain
Other Concerns: Handling waste right protects the ecosystem the best
Waste Disposal: Collect in drum or bottle, hand to licensed chemical disposal firm, never pour down the drain
Contaminated Packaging: Rinse well, dispose as chemical waste
Other Advice: Follow local and federal rules, get paperwork stamped if moving large amounts offsite
UN Number: Not regulated as hazardous under bulk shipping standards
Transport Hazard Class: Not applicable
Packing Group: Not regulated
Shipping Name: Polyethylene glycol dimethyl ether
Special Precautions: Bottle tops tight, mark clearly, separate from acids and oxidizers, check for leaks in transit
OSHA Status: Not specifically listed
TSCA: Listed
SARA Title III: Not a reportable substance
EC Directive: Not classified as dangerous for supply in the EU
Other Requirements: Labelling with product name and relevant symbols, safety measures on storage and use, annual review of handling by lab supervisors or chemical agents responsible
