Note to Physicians: Treat symptomatically based on patient’s reaction and exposure scenario
Suitable Extinguishing Media: Foam, dry powder, carbon dioxide, water spray
Unsuitable Extinguishing Media: Strong water jets can spread spilled product
Special Exposure Hazards: Combustion can release carbon oxides and minor acidic fumes
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and protective clothing, avoid inhalation of smoke or decomposition products
Specific Fire Risks: Product can form combustible mixtures at high temperatures though generally considered of low fire risk in standard use
Personal Precautions: Use personal protective equipment including gloves, goggles, and protective clothing, avoid inhalation of vapors and direct skin contact
Environmental Precautions: Prevent entry into waterways, drains, and soil, contain spill with inert absorbent materials such as sand or earth
Cleanup Methods: Soak up with absorbent material, collect in clearly labeled, sealable container for safe disposal, wash residue with water and mild detergent after cleanup
Reference to Other Sections: Refer to exposure controls and disposal measures as listed in this document
Safe Handling: Avoid unnecessary skin and eye contact, wash hands thoroughly after use, work in ventilated space to minimize inhalation of vapors
Storage Conditions: Store in tightly sealed containers in cool, dry, and well-ventilated areas away from direct sunlight and sources of heat or ignition
Incompatible Materials: Strong oxidizers, strong acids
Storage Class: Non-hazardous organic liquid
Occupational Exposure Limits: No specific occupational exposure limits established by OSHA, ACGIH, or EU standards
Engineering Controls: Provide adequate ventilation, mechanical exhaust recommended in manufacturing or large-scale use settings
Personal Protective Equipment (PPE): Protective gloves (nitrile or neoprene), chemical splash goggles, long-sleeved clothing; in industrial settings, use proper respirator if vapor generation is likely
Hygiene Measures: Wash hands before breaks and at end of workday, remove contaminated clothing and launder before reuse
Appearance: Clear, colorless to pale yellow oily liquid

Melting Point/Freezing Point: Below 0°C
Boiling Point/Range: Above 300°C
Flash Point: Over 200°C (open cup)
Evaporation Rate: Negligible at room temperature
Flammability: Not easily ignitable, but can support combustion at elevated temperatures
Vapor Pressure: Very low, less than 0.01 hPa at 20°C
Vapor Density: Heavier than air
Relative Density: Around 0.91–0.94 (water = 1)
Solubility: Insoluble in water, soluble in fats and organic solvents
Partition Coefficient (log Kow): Estimated >6
Auto-Ignition Temperature: Above 300°C
Decomposition Temperature: No significant decomposition below 300°C
Viscosity: Moderate, varies with temperature
Chemical Stability: Stable in recommended storage conditions and standard industrial environments, resists breakdown under normal use
Possibility of Hazardous Reactions: No dangerous reactions known under normal use and storage
Conditions to Avoid: Prolonged exposure to heat, open flame, strong oxidizing agents
Materials to Avoid: Strong acids, strong oxidizers; reactive metals can catalyze breakdown at high temperatures
Hazardous Decomposition Products: May yield carbon monoxide, carbon dioxide, and minor amounts of irritating or toxic fumes during fire or thermal decomposition
Acute Toxicity: Oral LD50 in rats >2000 mg/kg; low acute toxicity expected based on animal studies and similar esters
Skin Corrosion/Irritation: Mild, transient irritation possible after extended contact
Serious Eye Damage/Irritation: Minimal irritant in standard in vivo and ex vivo tests
Respiratory or Skin Sensitization: Unlikely; rare reports of mild skin sensitization, especially in sensitive individuals
Germ Cell Mutagenicity: No evidence of mutagenic effects from standard testing
Carcinogenicity: Not listed by NTP, IARC, or OSHA
Reproductive Toxicity: No data indicating adverse reproductive effects
Specific Target Organ Toxicity (STOT): Not expected to cause organ toxicity after single or repeated exposure
Aspiration Hazard: Low, owing to high viscosity and low volatility
Ecotoxicity: Limited data suggests low toxicity for aquatic organisms (fish LC50 >100 mg/L), major harm unlikely at environmentally relevant concentrations
Persistence and Degradability: Readily biodegradable in soil and aquatic conditions, expected to break down through standard microbiological processes
Bioaccumulative Potential: High log Kow may suggest some potential for accumulation, but rapid biodegradation significantly lowers risk
Mobility in Soil: Low due to hydrophobicity and strong binding to organic matter
Other Adverse Effects: No evidence for endocrine disruption or chronic toxicity to ecosystem components
Disposal Methods: Product residues and contaminated absorbents should be collected for incineration or high-temperature disposal at permitted hazardous waste facilities; avoid landfill
Container Disposal: Triple rinse empty containers, puncture and dispose in line with local or national regulations for chemical waste
Uncleaned Packaging: Handle as hazardous waste until effectively decontaminated
