Chemical Name: Propylene Glycol n-Butyl Ether
CAS Number: 5131-66-8
Concentration: ≥95% w/w
Impurities: Trace amounts of other glycol ethers (<1%); no hazardous additives declared under current regulations
Eye Contact: Rinse cautiously with water for 15 minutes; remove contact lenses if present
Skin Contact: Wash with soap and water; remove contaminated clothing
Inhalation: Move to fresh air; monitor for persistent symptoms like dizziness or headache
Ingestion: Rinse mouth, seek medical advice if symptoms occur, do not induce vomiting unless directed
Notes for Physicians: Treat based on symptoms; no known antidote as of latest data
Suitable Extinguishing Media: Water spray, alcohol-resistant foam, dry chemical, carbon dioxide
Specific Hazards: Can form combustible mixtures with air; vapors may travel long distances and flash back; fire yields toxic gases including carbon monoxide and carbon dioxide
Special Protective Equipment for Fire Fighters: Full protective gear and self-contained breathing apparatus
Advice: Use water spray to cool exposed containers; avoid direct contact with liquid runoff
Personal Precautions: Ventilate area, eliminate ignition sources, avoid contact with skin and eyes, wear protective clothing
Environmental Precautions: Prevent entry into drains, soil or waterways
Clean Up Methods: Absorb with inert material like sand or vermiculite; collect in suitable containers; clean spill surface with water; thoroughly ventilate area
Safe Handling: Use only with proper ventilation, ground containers when transferring liquid, avoid inhalation of vapor, prevent spills and contact
Storage Conditions: Store indoors, away from heat or ignition sources; keep container tightly closed; segregate from strong oxidizers and acids; store in original containers with labels intact
Occupational Exposure Limits: No established OSHA PEL or ACGIH TLV for beta isomer; general limit for similar glycol ethers is TWA of 50 ppm
Engineering Controls: Local exhaust recommended for high vapor areas
Personal Protective Equipment: Chemical goggles, gloves (nitrile, PVC, or butyl), lab coats; use respirator for vapor concentrations above limits or inadequate ventilation
Hygiene Measures: Wash hands after use, remove soiled clothing promptly
Appearance: Clear, colorless liquid
Odor: Mild ether odor
Boiling Point: Approximately 170°C (338°F)
Flash Point: About 68-70°C (closed cup)
Vapor Pressure: 0.4 mmHg at 20°C
Solubility in Water: Miscible
Density: About 0.88 g/cm³ at 20°C
pH: Not applicable for non-aqueous fluid
Viscosity: Low
Evaporation Rate: Slower than ethyl ether
Chemical Stability: Stable under recommended storage and use
Conditions to Avoid: Extreme heat, open flame, and sources of static electricity; prolonged exposure to air increases peroxide formation risk
Incompatible Materials: Strong oxidizers, acids
Hazardous Decomposition Products: Burning produces carbon monoxide, carbon dioxide, possibly small quantities of aldehydes
Possibility of Hazardous Reactions: None expected with proper handling
Acute Toxicity: Oral LD50 (rat) ranges from 3300 to 4000 mg/kg
Eye Effects: Irritation, redness, watering
Skin Effects: Mild or moderate local irritation
Inhalation Effects: Headache, nausea at high concentrations
Chronic Exposure: No human data revealing chronic systemic toxicity; animal studies find no clear carcinogenic risk
Other Effects: Not classified as mutagenic or reproductive toxin by regulatory bodies as of last review
Environmental Impact: Moderately biodegradable; material breaks down in aquatic environments within weeks
Acute Aquatic Toxicity: LC50 (Fish, 96h): typically above 1000 mg/L
Chronic Effects: No evidence of bioaccumulation or significant chronic toxicity to aquatic life
Persistence and Degradability: Expected rapid degradation; not persistent
Mobility in Soil: High mobility due to water miscibility
Waste Disposal: Follow national, state, local regulations; preferred method is incineration in chemical incinerator with afterburner and scrubber
Packaging Disposal: Rinse and recycle or send to licensed reconditioner; do not reuse empty containers for other purposes
Additional Advice: Avoid uncontrolled release to environment, do not dump into drains or watercourses
UN Number: Not classified as hazardous under UN Recommendations
