Product Name: Tripropylene Glycol
Chemical Formula: C9H20O3
Synonyms: TPG, Tripropyl Glycol
CAS Number: 24800-44-0
Manufacturer: Dow Chemical or similar industry sources
Use: Solvent, intermediate chemical, hydraulic fluids, plasticizer, fragrance carrier
Hazard Classification: Typically categorized under non-hazardous substances, but check specific regulatory listings
Physical Hazards: Can cause slippery surfaces, moderate irritant through direct contact with skin or eyes
Health Hazards: Possible irritation to eyes and skin, unlikely to be acutely toxic but large ingestion or inhalation may lead to discomfort
Environmental Hazards: Spills or leaks can contaminate water sources, suspected to have moderate aquatic toxicity in very high concentrations due to oxygen demand impacts
Main Ingredient: Tripropylene Glycol, purity above 95%
Impurities: Mono- and dipropylene glycols, trace propylene oxide residues
Additives: None typically present in commercial material
Inhalation: Move to fresh air, monitor for respiratory symptoms, provide oxygen if breathing difficulty occurs
Skin Contact: Remove contaminated clothing, wash affected area with soap and water
Eye Contact: Rinse with water for at least 15 minutes, keep eyelids open, seek medical attention for persistent irritation
Ingestion: Rinse mouth, drink water to dilute, seek medical help if a large amount swallowed or if symptoms develop
Suitable Extinguishing Media: Use dry chemical, foam, carbon dioxide, or water spray
Hazardous Combustion Products: May emit carbon monoxide, carbon dioxide, potentially irritating fumes under fire conditions
Special Protective Equipment: Firefighters should use full protective gear and self-contained breathing apparatus
Fire & Explosion Risk: Generally low; vapor is not likely to accumulate under normal conditions, but heat can cause pressure build-up in containers
Personal Precautions: Wear appropriate protective equipment including gloves and safety goggles, prevent skin and eye contact
Environmental Precautions: Prevent spillage from reaching soil, sewers, waterways
Containment: Absorb spilled liquid with inert material such as sand or earth
Cleanup: Collect in suitable containers for disposal; ventilate the area to remove vapors
Handling: Use with adequate ventilation, avoid splashing and direct contact, wash hands after handling
Storage Conditions: Store in tightly closed containers, away from heat, sparks, ignition sources, and strong oxidizing agents
Incompatibilities: Avoid contact with strong acids, strong bases, and powerful oxidizers
Recommendations: Use containers made of steel or polyethylene, keep away from food and beverages to prevent accidental ingestion
Engineering Controls: Provide local exhaust ventilation or general room ventilation to maintain vapor levels well below occupational limits
Personal Protection: Use gloves of neoprene or nitrile, chemical safety goggles, protective clothing in case of big spills
Respiratory Protection: Not typically required in open, ventilated environments; in confined spaces or during spill clean-up, wear a suitable respirator
Hygiene Measures: Wash hands before eating, drinking, or smoking after handling
Exposure Limits: Occupational limits not established for tripropylene glycol but general glycol exposure guidelines suggest keeping exposure low
Appearance: Clear, colorless to light yellow liquid
Odor: Faint, sweet odor
Boiling Point: Approximately 277°C (531°F)
Melting Point: -45°C (-49°F)
Flash Point: 149°C (300°F), closed cup
Vapor Pressure: Very low at room temperature
Solubility: Miscible with water, alcohols, ethers
Density: 1.012 g/cm³ at 25°C
Viscosity: Notably higher than water, creates a slightly oily feel
Stability: Stable under recommended storage and handling conditions
Hazardous Reactions: None anticipated under normal use; avoid contact with strong acids, bases, and oxidizers to prevent polymerization or decomposition
Decomposition Products: Mainly carbon monoxide and carbon dioxide if burned
Polymerization Risk: No hazardous polymerization expected
Acute Toxicity: Low; large doses may cause discomfort or transient symptoms like nausea or diarrhea
Skin Irritation: Prolonged contact may cause minor irritation
Eye Irritation: Direct contact causes discomfort, redness
Long-term Exposure: No significant health data links chronic exposure to severe outcomes; always observe safe handling standards
Inhalation Risks: Breathing in high vapor concentrations in poorly ventilated spaces can irritate mucous membranes
Aquatic Toxicity: Not considered highly toxic but large quantities can reduce oxygen levels in water and impact aquatic organisms
Persistence and Degradability: Readily biodegradable in soil and water
Bioaccumulation Potential: Low; limited potential for bioaccumulation
Soil Mobility: High due to water solubility; spilled product may migrate to groundwater without proper containment
Waste Treatment Methods: Recycle whenever possible using local reprocessing schemes, or incinerate in an approved facility
Disposal of Product: Dispose as non-hazardous industrial waste where approved, prevent entry into surface water, drains, or soil
Disposal of Packaging: Clean thoroughly for recycling or dispose according to local regulations; uncleaned containers may present a hazard
UN Number: Not classified as dangerous for transport in most regions
Transport Hazard Class: Non-hazardous for road, rail, air, and sea
Packing Group: Not applicable
Special Transport Precautions: Secure containers, avoid leaks, mark as chemical liquids, keep upright during transport
Regulation Listings: Not listed as a controlled substance under most workplace safety frameworks; check local and national regulations for updates
Labeling Requirements: Provide basic identification and hazard information on packaging
SARA Title III (US): Not a reportable substance
REACH Status (EU): Generally registered and allowed for import, export, and use
Other Requirements: Employers must inform workers about risks associated with workplace chemicals and maintain proper MSDS access as per OSHA or other relevant regulations; keep updated with any significant regulatory revisions.
