Chemical Name: Dipropylene Glycol Dimethyl Ether
CAS Number: 111109-77-4
Concentration: %98-100 by weight
Impurities: No major impurities expected over 1%
Inhalation: Take affected person to fresh air, allow rest, provide oxygen if breathing is difficult, seek medical attention for continued discomfort
Skin Contact: Remove contaminated clothing, wash exposed skin with running water and mild soap, monitor for dryness or rash, medical attention for persistent irritation
Eye Contact: Rinse eyes with plenty of water for at least 15 minutes, hold eyelids open; seek medical assistance without delay if irritation persists
Ingestion: Rinse mouth, seek immediate medical attention; do not induce vomiting, give small amounts of water if conscious, monitor breathing and level of consciousness
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical, CO2, or water fog
Unsuitable Extinguishing Media: Do not use high-pressure water jets directly on burning liquid
Fire Hazards: Vapors are heavier than air, potential for travel to ignition sources and flashback; burning generates irritating or toxic fumes, including carbon monoxide and carbon dioxide
Protective Equipment: Firefighters should use self-contained breathing apparatus and full protective gear, stay upwind to avoid vapor exposure
Personal Precautions: Wear gloves, splash-resistant goggles, and chemical-resistant clothing; avoid breathing vapor, evacuate unprotected personnel
Environmental Precautions: Prevent product from entering drains, soil, or surface waters; alert authorities if spill contaminates environment beyond containment area
Containment and Cleanup: Absorb with inert material (sand or earth), collect in suitable labeled containers for disposal, clean area with water and detergent, ventilate affected place thoroughly before re-entry
Handling: Use in well-ventilated areas, keep away from hot surfaces, sparks, open flames; avoid contact with skin and eyes, use personal protective equipment as recommended; avoid breathing vapors during transfer and mixing
Storage: Keep in tightly closed, properly labeled containers in a cool, dry, well-ventilated place; store away from strong oxidizing agents, acids, and direct sunlight; sensitive to moisture; store only in equipment compatible with ethers
Exposure Limits: No specific occupational exposure limits established, General vapor exposure limit recommended (ACGIH TLV-Guideline: 50ppm - consult national regulations)
Engineering Controls: Local exhaust ventilation; ensure operations are closed or contained
Personal Protection: Safety goggles or face shield, chemical-resistant gloves (nitrile, neoprene), anti-static footwear, lab coat or apron; use NIOSH-approved respirator for airborne concentrations exceeding recommendations
Hygiene Measures: Wash hands before eating, drinking, or smoking; remove and wash contaminated clothing before reuse
Appearance: Colorless transparent liquid
Odor: Slight, ether-like odor
Odor Threshold: Not established
pH: Not applicable (non-aqueous liquid)
Melting Point/Freezing Point: <-80°C
Boiling Point/Range: 175-180°C
Flash Point: 65°C (closed cup)
Evaporation Rate: Slower than diethyl ether
Flammability: Flammable liquid
Upper/Lower Flammability Limits: Lower 1.1%; Upper 12% by volume in air
Vapor Pressure: 0.35 mmHg at 20°C
Vapor Density: 5.5 (air=1)
Relative Density: 0.91-0.93 at 20°C
Solubility: Miscible with water, alcohol, most common organic solvents
Partition Coefficient (n-octanol/water): log P = –0.4
Auto-ignition Temperature: 220°C
Decomposition Temperature: >200°C
Viscosity: 3.7 cP at 25°C
Chemical Stability: Stable under recommended conditions
Possibility of Hazardous Reactions: May form peroxides over prolonged storage with exposure to air
Conditions to Avoid: Heat, sparks, open flames, static discharge, moisture
Incompatible Materials: Strong oxidizing agents, strong acids, strong bases, chlorinated compounds, certain plastics
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, under fire conditions combustion may release toxic vapors
Acute Toxicity: Oral LD50 (rat): >2000 mg/kg; Dermal LD50 (rabbit): >2000 mg/kg
Inhalation: May cause respiratory tract irritation, dizziness, headache, or central nervous system depression at higher concentrations
Skin Contact: May lead to mild irritation, dermatitis with repeated or prolonged exposure
Eye Contact: Causes mild to moderate irritation; risk of corneal injury upon splash
Chronic Toxicity: No long-term effects noted at typical industrial exposure levels; data gap for reproductive or carcinogenic effects
Sensitization: Unlikely to cause skin sensitization
Mutagenicity/Carcinogenicity: No available evidence of mutagenic or carcinogenic effects in animal studies
Ecotoxicity: Not expected to be acutely toxic to aquatic organisms based on structure-activity data
Persistence and Degradability: Readily biodegradable in standard tests, breakdown in water and soil occurs within days to weeks
Bioaccumulation Potential: Low (log Kow <1), little likelihood of significant bioaccumulation
Mobility in Soil: Very high, potential for leaching to groundwater if spilled
Other Effects: Large spills may result in oxygen depletion of surface waters, unlikely to impact endocrine systems or long-term aquatic survival
Waste Disposal Methods: Incinerate at authorized chemical incinerator, follow all local, regional, and national environmental regulations; containers should be drained, triply rinsed, and managed as hazardous waste
Special Precautions: Do not discharge to sewers or surface waters; obtain permits if disposal is outside routine waste handling processes; consult local environmental authority for specific recommendations
