Ingestion: Rinse mouth thoroughly with water; do not induce vomiting; seek medical attention for persistent discomfort
Other First Aid Notes: Wash contaminated clothing before reuse; consult local poison information service for large exposures
Suitable Extinguishing Media: Use dry chemical, foam, or carbon dioxide extinguishers; water spray may cool containers but might not be effective for direct extinguishing
Fire Hazards: Combustion can release oxides of carbon and possible traces of toxic fumes; heated oil can ignite
Special Protective Equipment: Wear full protective gear and self-contained breathing apparatus; prevent runoff to sewers
Explosion Data: Oil mist may form explosive mixtures with air under certain conditions
Specific Fire-Fighting Procedures: Contain fire-fighting water to avoid environmental contamination; evacuate unnecessary personnel
Personal Precautions: Keep unnecessary personnel away; avoid inhalation of vapors or mist; wear skin and eye protection
Environmental Precautions: Prevent entry into waterways, drains, or soil
Cleanup Methods: Absorb with earth, sand, or inert material; transfer residue to container for disposal; clean contaminated area with suitable detergent
Disposal of Residue: Dispose in compliance with local, regional, and national regulations
Handling: Use in well-ventilated areas; avoid formation of oil mist; wash hands after handling; avoid contact with eyes and prolonged skin exposure
Storage Conditions: Store in tightly sealed containers away from heat and ignition sources; keep away from oxidizing materials
Incompatibility: Avoid contact with strong oxidizers and acids
Special Measures: Store in original container or approved alternative; protect from physical damage
Hygiene Measures: Do not eat, drink, or smoke while handling materials
Occupational Exposure Limits: No established limits for finished material; control oil mist to below ACGIH TLV of 5 mg/m³ (as mineral oil mist)
Engineering Controls: Use with adequate ventilation or local exhaust; containment systems for transfer and blending
Personal Protective Equipment: Safety goggles, impervious gloves (nitrile or PVC), work clothing; use oil-resistant boots for spill response
Respiratory Protection: Use NIOSH-approved respirators if mists or vapors exceed recommended levels
Environmental Exposure Controls: Prevent release to external environment; industrial wastewater treatment recommended
Appearance: Clear to pale yellow liquid; viscous at room temperature
Odor: Mild, vegetable oil-like
pH: Not applicable (insoluble in water)
Melting/Freezing Point: Approximately -20°C to -10°C
Initial Boiling Point: Decomposes above 300°C
Flash Point: Approximately 280°C (Closed cup method)
Evaporation Rate: Not volatile; negligible at ambient conditions
Flammability (solid, gas): Not classified as flammable, but can ignite at high temperatures
Vapor Pressure: Less than 0.01 mmHg at 25°C
Vapor Density: Not available
Solubility: Practically insoluble in water; soluble in alcohols, esters, and many organic solvents
Partition Coefficient (n-octanol/water): >6
Auto-Ignition Temperature: Above 330°C
Decomposition Temperature: Greater than 300°C
Viscosity: High viscosity, typically 75-110 cSt at 40°C
Relative Density: 0.93-0.96 g/cm³ at 25°C
Chemical Stability: Stable under recommended storage and handling conditions
Reactivity: Not reactive with most common substances in typical industrial applications
Conditions to Avoid: Avoid excessive heat, open flames, and direct sunlight; prolonged exposure to high temperatures can break down the ester
Incompatible Materials: Strong oxidizing agents (e.g. peroxides, nitric acid), strong acids, alkali metals
Hazardous Decomposition Products: Thermal decomposition or incomplete combustion produces hazardous gases including carbon monoxide, carbon dioxide, and smoke
Polymerization: Not expected under normal handling conditions
Acute Toxicity: Based on available data for structurally similar triesters and fatty acids, oral LD50 is estimated above 5,000 mg/kg (rat); not classified as toxic
Skin Corrosion/Irritation: Non-irritating or minimally irritating in typical use; long-term exposure may cause mild irritation
Eye Damage/Irritation: May cause mild, reversible irritation
Respiratory Sensitization: Not expected based on chemical structure and low volatility
Skin Sensitization: Not a skin sensitizer in animal studies
Germ Cell Mutagenicity: Not known to cause mutagenic effects
Carcinogenicity: No evidence of carcinogenicity in long-term animal feeding studies with related fatty acids
Reproductive Toxicity: No known data indicating hazard to reproduction or development
Specific Target Organ Toxicity—Single Exposure: Not expected at industrial handling levels
Specific Target Organ Toxicity—Repeated Exposure: No target organs identified; practice good industrial hygiene
Aspiration Hazard: Not expected due to low volatility and viscosity, but aspiration of large quantities could cause lipid pneumonia
Ecotoxicity: Generally considered non-toxic to aquatic life at typical discharge levels; acute LC50/EC50 for fish and invertebrates above 100 mg/L
Persistence and Degradability: Slowly biodegradable in the environment; long-chain esters degrade to fatty acids and glycerol derivatives over time
Bioaccumulative Potential: High partition coefficient suggests potential to concentrate in organisms, but rapid metabolism reduces actual risk
Mobility in Soil: Low mobility due to high viscosity and hydrophobic nature; may persist at spill sites
Other Adverse Effects: Large releases may coat gills or physical surfaces, harming wildlife by oxygen depletion
Disposal Methods: Send material to approved incineration or recycling facility; do not dump into sewers, surface water, or uncontrolled sites
Container Disposal: Rinse empty containers with small amount of compatible solvent; dispose as hazardous waste or offer for recycling according to local laws
