Chemical Name: Propylene Glycol Propyl Ether
Common Synonyms: 1-Methoxy-2-propanol, PGPE
Recommended Uses: Solvent for coatings, cleaners, inks, and industrial fluids
Appearance: Clear, colorless liquid
Odor: Faint, ether-like scent
Molecular Formula: C6H14O2
Molecular Weight: 118.2 g/mol
Hazard Class: Skin and eye irritant
Target Organs: Eyes, respiratory tract, skin
GHS Symbol: Exclamation mark (irritation warning)
Route of Entry: Inhalation, absorption through skin, ingestion
Acute Effects: Coughing, sore throat, redness, irritation, headaches
Chronic Effects: Prolonged contact can cause dermatitis or liver stress in sensitive individuals
Main Ingredient: Propylene Glycol Propyl Ether (CAS: 1569-01-3)
Concentration: Typically above 95% when sold in bulk
Impurities: May contain trace levels of other glycols due to manufacturing process
Inhalation: Move to fresh air, keep person calm; if breathing difficulty continues, seek medical help
Skin Contact: Wash thoroughly with soap and water; remove contaminated clothing
Eye Contact: Rinse cautiously with water for several minutes; remove contact lenses if present
Ingestion: Rinse mouth, do not induce vomiting; consult a doctor right away
Notes to Healthcare Providers: Treat symptomatically; monitor for respiratory distress or skin irritation
Suitable Extinguishing Agents: Water spray, dry chemical, foam, carbon dioxide
Specific Hazards: Vapors may form explosive mixtures with air, especially in unventilated spaces
Special Protective Equipment: Firefighters should use self-contained breathing apparatus
Thermal Decomposition: Generates toxic fumes such as carbon monoxide and carbon dioxide if combusted
Explosion Risk: Moderate; airborne vapors can ignite above flash point (around 47°C)
Evacuation Advice: Clear area for large spills, ventilate enclosed spaces
Containment Procedures: Use sand, earth, or vermiculite to contain spread
Cleanup: Absorb with inert material, collect into sealed, labeled containers for disposal
Personal Protection: Avoid inhalation and skin contact with spilled material by using gloves, goggles, and respirator if needed
Handling Precautions: Keep containers tightly closed, avoid inhaling vapors, minimize skin contact
Storage Guidance: Store in cool, well-ventilated area, away from sparks, open flames, and incompatible chemicals
Incompatibilities: Strong acids, oxidizers, and bases; avoid contact with aluminum at high temperature
Storage Containers: Use containers made from compatible plastics or lined steel
Occupational Limits: No specific OSHA PEL or ACGIH TLV, but industry good practice keeps airborne concentrations below 50 ppm
Engineering Controls: Local exhaust ventilation, especially in confined areas
Personal Protection: Protective gloves (nitrile or latex), safety goggles, lab coat or coveralls
Respiratory Protection: Respirator for tasks generating significant vapor or mist
Hygiene Measures: Wash hands thoroughly after handling, do not eat or drink in the workspace
Physical State: Liquid
Color: Colorless
Odor: Mild, ether-like
Boiling Point: About 146°C
Flash Point: Around 47°C
Solubility in Water: Moderately soluble
Vapor Pressure: Low at room temperature
Density: Approximately 0.92 g/cm³
Chemical Stability: Stable under normal conditions, breaks down under sustained heat or flame
Reactivity: May react with strong oxidizers, acids, or bases to release heat and fumes
Hazardous Decomposition: Combustion or prolonged heating can produce carbon oxides, small amounts of other organic compounds
Acute Toxicity: Low to moderate by oral or inhalation exposure
Skin Effects: Mild to moderate irritation with extended contact
Eye Effects: Redness and watering, typically resolves within a day with rinsing
Long-Term Risks: No evidence of cancer or reproductive harm in available studies; large, repeated exposures may stress the liver and kidneys
Common Symptoms: Headache, dizziness, nausea if vapors inhaled at high levels
Aquatic Toxicity: Moderately toxic to aquatic organisms with direct release
Persistence: Biodegradable in soil and water under most conditions
Bioaccumulation: Low potential, breaks down in the environment over weeks
Precaution: Avoid spills or disposal into drains, natural waterways, or soil
Waste Handling: Collect waste in sealed, labeled containers
Disposal Recommendation: Use licensed waste disposal contractors; incinerate or landfill according to local regulations
Reuse/Recycling: Only possible if purity is guaranteed and aligns with intended next use
Environmental Responsibility: Never pour leftover Propylene Glycol Propyl Ether down the drain or outside
Classification: Can be regulated as a flammable liquid depending on quantity and flash point. Check local guidelines for shipping and storage
UN Number: Listed as UN 3272 where regulated
Transport Hazards: Avoid leaks and sources of ignition during transport; secure containers well
Packaging Requirements: Use approved containers and proper labels in transit
Chemical Inventory: Listed in the US TSCA Inventory and similar registers in Europe and Asia
Labeling Requirements: Warning for skin and eye irritation, flammability warning required on containers
Workplace Control: Employers must offer safety training, provide access to protective gear, and maintain proper ventilation where this material is handled
Environmental Regulations: Spills and releases might need immediate reporting to authorities if above set thresholds
