First Aid Measures

Eye Contact: Rinse with plenty of water for 10–15 minutes, holding eyelids open; remove contact lenses;
Skin Contact: Wash thoroughly with soap and water; remove contaminated clothing;
Inhalation: Move person to fresh air; seek medical attention if symptoms persist;
Ingestion: Rinse mouth; do not induce vomiting; call poison control for advice;

Fire-Fighting Measures

Suitable Extinguishing Media: Use dry chemical, CO2, foam, or water spray; large fires may require specialized foam
Special Hazards: Decomposition may evolve carbon monoxide, carbon dioxide, and organic vapors
Protective Equipment: Full protective gear and self-contained breathing apparatus;
Firefighting Advice: Prevent runoff from entering drains and waterways;

Accidental Release Measures

Personal Precautions: Evacuate personnel; wear suitable personal protection including gloves and goggles;
Containment: Absorb spills with inert material, collect in suitable containers for disposal;
Cleaning Method: Wash affected area with detergent; ventilate spill site;
Environmental Precautions: Prevent release to drains, soil, and waterways;

Handling and Storage

Safe Handling: Use with good ventilation; avoid breathing vapor or mist; keep away from food and drink sources;
Storage Conditions: Store in sealed, labeled containers in cool, dry, well-ventilated areas away from heat and direct sunlight;
Incompatible Materials: Strong acids, bases, and oxidizing agents;
General Hygiene: Wash hands after use; avoid eating, drinking, or smoking in work area;

Exposure Controls and Personal Protection

Occupational Exposure Limit: No established OSHA or ACGIH limits for this product;
Engineering Controls: Ensure good ventilation; use local exhaust if available
Personal Protective Equipment: Protective goggles or face shield, nitrile or neoprene gloves, chemical-resistant apron for bulk work
Respiratory Protection: Required only if vapor or mist present at higher than safe levels;
Environmental Controls: Prevent spillage from entering drains or watercourses;

Physical and Chemical Properties

Appearance: Clear, oily liquid
Odor: Mild characteristic ester odor
pH: Not measurable in water
Boiling Point: 389°C (estimated)
Melting Point: -28°C (estimated)
Flash Point: >200°C (closed cup), low volatility
Solubility in Water: Negligible
Density: Approx. 1.01 g/cm³ at 20°C
Viscosity: Moderate viscosity typical of higher esters
Partition Coefficient (log Kow): Estimated to be moderately high, indicating potential for bioaccumulation;

Stability and Reactivity

Chemical Stability: Stable under standard storage and handling conditions
Reactivity: Inert to most common substances; will hydrolyze slowly in strong acid or alkali
Conditions to Avoid: Excessive heat, open flames, ultraviolet light, moisture
Incompatible Materials: Strong oxidizers, concentrated acids and bases
Decomposition Products: Burning produces carbon monoxide, carbon dioxide, hydrocarbon fragments

Toxicological Information

Acute Toxicity: Low acute toxicity; oral LD50 (rat) >5000 mg/kg
Skin Corrosion/Irritation: May irritate after repeated or prolonged exposure
Eye Damage/Irritation: Can cause mild, reversible irritation
Respiratory Sensitization: No data showing respiratory sensitization in humans or animals
Carcinogenicity: Not listed by IARC, NTP, or OSHA
Mutagenicity: No evidence found in standard tests;
Target Organs: No evidence of organ-specific toxicity from available data;

Ecological Information

Environmental Fate: Slowly biodegradable in soil and water; may form bioaccumulative residues because of high log Kow;
Aquatic Toxicity: Low acute toxicity to fish and daphnia (LC50 >100 mg/L); chronic effects data limited
Soil Mobility: Expected low mobility in soil due to high hydrophobicity;
Biodegradation: Incomplete under most aquatic conditions, more rapid in composting or high-microbial soils

Disposal Considerations

Disposal Methods: Incinerate in licensed facility if available; landfilling in approved sites if incineration not possible; avoid discharge to aquatic environments;
Regulatory Disposal Code: Follow local, regional, and national hazardous waste disposal regulations for organic chemicals;
Packaging Disposal: Triple rinse containers before recycling or disposal per regulations;
