Classification: Not classified as hazardous under GHS; may cause mild irritation on direct, repeated contact
Label Elements: No pictogram required under GHS rules, precautionary statements for safe handling recommended
Health Hazards: Short contact with eyes or skin can cause mild, short-term irritation; inhalation of high concentrations may cause headache or dizziness
Environmental Hazards: Material does not easily accumulate in water or soil, but spills or high concentrations can cause local harm to aquatic life
Precautionary Statements: Use only with suitable ventilation, keep container tightly closed, avoid unnecessary skin contact
Chemical Identity: Dipropylene Glycol Methyl Propyl Ether
Purity: Usually at least 98% pure
Impurities: Low amounts of related glycol ethers and trace water, which do not typically alter risk profile
Additives: No stabilizers or inhibitors generally added
Concentration: Single-component substance in standard supplied form
Eye Contact: Flush slowly with clean water for at least 15 minutes; check for persistent stinging or redness before deciding if further care is needed
Skin Contact: Wash with soap and water; use of industrial skin cleaner may remove stubborn residues; seek medical attention if rash or extreme discomfort develops
Inhalation: Move away from vapor into fresh air; if breathing feels difficult, get medical help without any delay
Ingestion: Rinse mouth with water if conscious, do not induce vomiting, and contact medical services for further instructions
Medical Attention: Rapid supportive care ensures recovery in most situations; symptoms generally clear up without lasting harm
Extinguishing Media: Any commercial foam, carbon dioxide, dry powder, or water spray recommended
Unsuitable Media: Avoid full-force water jet, since product may splash and spread
Specific Hazards: Heated liquid can produce flammable vapors which may travel; burning releases carbon dioxide, carbon monoxide, and small amounts of organic fumes
Protective Equipment: Standard full bunker gear and self-contained breathing apparatus limit exposure for fire fighters
Firefighting Techniques: Keep containers cool with spray if exposed to flames or heat
Personal Precautions: Wear chemical resistant gloves, protective goggles, and long sleeves
Spill Response: Absorb spill with inert material such as sand or vermiculite; gather and place into a closed, labeled container
Environmental Protection: Block flow to drains or water sources; alert environmental authorities if major spill reaches open waterways
Clean-up Methods: Use water and mild detergent after removal; ventilate area well; disposal follows approved local guidelines
Handling Practices: Practice careful movement to avoid spills, begin work in areas with tested local ventilation systems
Hygienic Measures: Wash hands after contact and before meals; avoid eating or drinking in work zone
Storage Temperature: Store in sturdy, upright containers at ambient temperature, shielded from heat sources and direct sunlight
Compatible Materials: Most metals, plastics, and glass show resistance; avoid strong acids, bases, and oxidizers
Incompatibilities: Long exposure to high temperatures or open flames can decompose material
Occupational Limits: No set ACGIH TLV or OSHA PEL, but exposure in area with good airflow is the norm
Engineering Controls: Use local exhaust or general room ventilation
Personal Protection: Wear chemical-resistant gloves (nitrile, neoprene), safety glasses, and, if vapor builds up, a NIOSH-approved respirator
Other Protection: Aprons and boots add safety where splashing is likely
Monitoring: Regular review of air concentrations and skin exposure in high-use areas keeps risks controlled
Appearance: Clear, colorless liquid with mild, faintly sweet odor
Odor Threshold: Not readily detectable at usual levels
pH: Not applicable, product is a neutral solvent
Melting Point: Less than -80°C
Boiling Point: Ranges between 210°C and 230°C
Flash Point: 98°C to 115°C (closed cup methods vary between reports)
Evaporation Rate: Low; evaporates more slowly than water
Flammability: Not easily ignited at typical room temperature
Vapor Pressure: 0.07 mmHg at 25°C
Vapor Density: Greater than air
Solubility: Miscible with water, alcohols, and most organic solvents
Partition Coefficient (n-octanol/water): Log Kow 0.4-1.5, low bioaccumulation potential
Decomposition Temp: Over 200°C, forms smaller ethers and alcohols under intense heating
Viscosity: 5 to 8 mPa·s at 25°C
Stability: Remains stable under recommended storage and handling conditions
Reactivity: Reacts only under severe chemical or heat stress
Hazardous Polymerization: Not expected in standard use
Hazardous Decomposition: Exposed to extreme heat, releases carbon dioxide, carbon monoxide, and trace hydrocarbon fumes
Incompatible Substances: Strong acids, strong bases, oxidizing agents intensify breakdown
Conditions to Avoid: High temperatures, sources of ignition, and open flames produce worst-case byproducts
Acute Toxicity: Oral LD50 in rats above 4000 mg/kg; not acutely toxic in most accidental exposures
Skin/Eye Irritation: Mild, reversible redness or dryness in rare prolonged exposures
Sensitization: No evidence of chronic effects or allergy from normal work
Chronic Effects: Limited evidence for long-term risk at workplace levels; no clear links to cancer or organ damage
Exposure Routes: Most common through skin contact or inhalation of fine mist; ingestion rare in normal use
Mutagenicity/Carcinogenicity: No indication of genetic risks or cancer association from available studies so far
Aquatic Toxicity: No strong evidence of threat at low release levels; LC50 (fish, 96h) above 100 mg/L, so not toxic at usual concentrations
Persistence: Product breaks down in water or soil through biological action, usually within weeks
Bioaccumulation: Tests show little build up in living tissue due to water solubility and fast breakdown
Mobility: Moves easily with water, so spills should be blocked to prevent contamination
Other Effects: Large spills in enclosed water may deplete oxygen as microbes degrade residue
Waste Handling: Collect waste in closed metal, plastic, or glass containers marked for solvents
Local Disposal: Approved waste vendors handle solvent recycling or incineration
EPA Identification: Not considered hazardous waste under RCRA if pure, but always check with local rules
Container Disposal: Triple rinse and recycle or dispose in approved facility
Spill Residue: Treat leftover with absorbent, follow up with soap and water for area, consult with authorities for environmentally sensitive regions
