Chemical Name: 3-Ethoxyethyl Propionate
Purity: Usually more than 98%
Impurities: Possible traces of 3-ethoxyethanol and propionic acid (generally less than 1%)
Other Components: Not blended with intentionally added substances
Inhalation: Move person out into fresh air at once; seek medical attention if symptoms like headache, nausea, or dizziness develop; give artificial respiration if not breathing
Skin Contact: Remove contaminated clothing instantly; rinse skin with plenty of water for at least 15-20 minutes; wash with soap and water; seek medical advice if irritation persists
Eye Contact: Rinse cautiously under running water for a minimum of 15 minutes while lifting eyelids; remove contact lenses if present; continue rinsing; get medical help without delay
Ingestion: Do not induce vomiting; rinse mouth thoroughly; get immediate medical attention; do not give anything by mouth to an unconscious person
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical powder, carbon dioxide, or water spray
Specific Hazards: Vapors can travel to a source of ignition and flash back; combustion creates toxic and irritating vapors such as carbon monoxide, carbon dioxide, and organic compounds
Special Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full protective gear; fight fire from upwind; maintain distance from storage tanks; use water spray to cool containers and disperse vapors
Explosion Data: Vapor/air mixtures may explode if exposed to ignition sources
Personal Precautions: Wear chemical-resistant gloves, splash-proof eye protection, flame-resistant clothing; remove ignition sources; ventilate area
Environmental Precautions: Contain the spill to prevent runoff into drains, sewers, or aquatic systems
Methods for Clean-Up: Absorb liquid with inert materials like sand or diatomaceous earth; collect in labeled containers for proper disposal; wash spill area thoroughly with water; avoid creating sparks; do not use combustible materials for cleaning up
Handling: Use only in well-ventilated locations; eliminate all possible sources of ignition; keep away from incompatible materials such as acids, oxidizers, and bases; avoid contact with eyes, skin, and clothing; never siphon by mouth
Storage: Store in tightly closed containers in a cool, dry, fireproof area with good ventilation; segregate from strong acids, oxidizers, peroxides; grounding and bonding for bulk storage; labeled and locked cabinets for small containers; keep away from direct sunlight and sources of heat
Exposure Limit (OSHA PEL): Not specifically established in the USA; recommendation to follow local workplace limits where available
Engineering Controls: Explosion-proof ventilation system; use fume hoods or local exhaust in risk areas
Personal Protective Equipment (PPE): Nitrile or neoprene gloves, chemical safety goggles, flame-retardant work clothing, face shield for splash hazards, rubber boots; use a certified respirator if vapor concentration becomes high or unknown
Hygiene Measures: Never eat, drink, or smoke in work areas; wash hands before breaks and after finishing work; remove and wash contaminated clothing before reuse
Appearance: Clear, colorless to slightly yellow liquid
Odor: Mild, ether-like
Boiling Point: 169-172°C (336-342°F)
Melting Point: Below -70°C (-94°F)
Flash Point: 54-59°C (129-138°F, closed cup)
Flammability: Flammable liquid
Vapor Pressure: 2.62 mmHg (20°C)
Vapor Density: 5 (air = 1)
Specific Gravity: 0.96 (20°C)
Solubility in Water: Moderately soluble
Partition Coefficient Octanol/Water (log Kow): About 1.0
Evaporation Rate: Slower than ether
Autoignition Temperature: 251°C (484°F)
Decomposition Temperature: Data not available
Chemical Stability: Stable under recommended storage and handling conditions
Reactivity: Reacts with strong oxidizers, acids, and bases; heat and light accelerate decomposition
Conditions to Avoid: Sparks, open flame, high temperatures, contact with incompatible chemicals, direct sunlight
Hazardous Decomposition Products: Carbon oxides, irritating organic vapors
Hazardous Polymerization: Not expected under normal conditions
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Toxicity: Oral LD50 in rats: 4300 mg/kg; Inhalation LC50 in rats (4h): > 5 mg/L; Dermal LD50 in rabbits: > 2000 mg/kg
Symptoms: Headache, dizziness, nausea, drowsiness, irritation of eyes and respiratory tract; high exposure may cause nervous system depression
Chronic Effects: Prolonged exposure may cause damage to organs (particularly liver and kidneys) in animals; reproductive toxicity data limited but not conclusive
Other Information: No data showing carcinogenicity in humans; repeated overexposure best avoided due to uncertainty of long-term effects
Aquatic Toxicity: Harmful to aquatic life in concentrated spills; LC50 fish (96h): roughly 150 mg/L; EC50 daphnia: about 100-300 mg/L
Environmental Persistence: Moderately biodegradable in soil and water
Mobility in Soil: Expected to have moderate mobility; can reach groundwater with improper containment
Bioaccumulation: Low potential due to solubility and partition coefficient
Other Hazards: Do not discharge into drains, waterways, or soil in significant amounts; large spills require reporting to local authorities
Waste Treatment Methods: Dispose through licensed chemical waste contractor; incinerate in approved facility; do not pour down drains or mix with household garbage
Packaging Disposal: Triple rinse containers before disposal or recycling; remove labels before recycling if regulations require
Contaminated Products: Treat contaminated absorbents or tools as hazardous waste
