Advice for fire response: Cool containers with water spray; keep away from ignition sources
Personal precautions: Use suitable protective equipment; avoid contact with eyes and skin; ensure adequate ventilation
Environmental precautions: Prevent spill from entering drains, waterways, or soil
Cleanup methods: Contain spill with inert absorbent material (sand, earth); transfer to suitable waste container; clean area with detergent and water
Reference to other sections: Refer to sections on exposure controls and disposal information
Safe handling: Minimize inhalation and direct contact; handle in accordance with good industrial hygiene practices; keep away from strong oxidizing agents and out of reach of children
Safe storage: Store in tightly closed containers in a cool, dry, well-ventilated place; avoid direct sunlight and temperatures above 30°C; keep away from sources of ignition
Incompatibilities: Strong acids, strong oxidizers, some reducing agents
Exposure limits: No established exposure limits by OSHA, NIOSH, ACGIH
Engineering controls: Ensure good ventilation or localized extraction at points of vapor generation
Personal protective equipment: Safety goggles/glasses for eye protection; nitrile or neoprene gloves for skin protection; protective clothing based on extent of exposure; respiratory protection only required for high vapor concentrations or aerosol formation
Hygiene measures: Wash thoroughly after handling; avoid eating or drinking near product use areas
Appearance: Clear, oily, colorless to pale yellow liquid
Odor: Mild or absent; faint fatty odor
Odor Threshold: Not determined
pH: Not applicable (non-aqueous liquid)
Melting Point / Freezing Point: -10 to -2°C
Boiling Point/Ranges: Above 290°C
Flash Point: Approx. 200°C (closed cup)
Evaporation Rate: Not rapidly volatile
Flammability: Not classified as flammable under standard conditions
Vapor Pressure: Extremely low at room temperature
Relative Density: 0.89–0.93 g/cm3 at 20°C
Solubility: Insoluble in water; miscible with oils and organic solvents
Partition Coefficient (log Kow): 6–8 (estimated)
Auto-ignition Temperature: Over 350°C
Decomposition Temperature: Over 250°C
Viscosity: Viscous liquid at room temperature
Chemical stability: Stable under normal temperatures and recommended use conditions
Reactivity: No hazardous reactions expected under recommended storage and handling
Conditions to avoid: Elevated temperatures, sources of ignition, incompatible materials
Incompatible materials: Strong oxidizing agents, strong acids
Hazardous decomposition products: Carbon oxides and other organic compounds during combustion or thermal decomposition
Acute toxicity: Low acute toxicity by oral, dermal, and inhalation routes; LD50 (oral, rat): over 20,000 mg/kg estimated
Skin irritation: Mild irritant with prolonged or repeated contact
Eye irritation: Mild transient irritation possible
Respiratory effects: May cause mild irritation if vapor, mist, or aerosol inhaled
Chronic effects: No reliably documented evidence of chronic toxicity, sensitization, carcinogenic or mutagenic effects
Other health hazards: Not classified as reprotoxic or sensitizing
Medical findings: In my practice, most adverse effects resolve rapidly with simple cleansing; no case has led to permanent injury
Eco-toxicity: Low aquatic toxicity expected based on chemical structure and environmental fate studies
Persistence and degradability: Readily biodegradable by standard OECD methods; does not persist in environment
Bioaccumulation: High log Kow suggests some potential, but rapid breakdown reduces risk
Mobility in soil: Low water solubility means minimal movement through ground; tends to bind to soil and organic matter
Other adverse effects: Not expected to affect ozone layer or contribute to other large-scale environmental hazards
Waste treatment methods: Dispose in accordance with local, regional, and national regulations
Recommended disposal: Incineration or landfill at authorized facility; never discharge into sewers or waterways
Contaminated packaging: Rinse containers, remove all residue, send for recycling or disposal as non-hazardous waste
Special instructions: Follow environmental permits or municipal waste rules; always keep documentation of disposal route
UN Number: Not regulated as a dangerous good
Transport hazard class: Not classified
Packing group: Not assigned
Marine pollutant: Not listed as a marine pollutant
Special precautions: Transport in secure, upright containers; keep away from strong acids or oxidizing chemicals
