Chemical Nature: Ester mixture (reaction products of propylene glycol with octanoic and decanoic acids)
Inhalation: Move to fresh air, supervise for symptoms of irritation, offer symptomatic support
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water, monitor for redness or irritation
Eye Contact: Rinse immediately with plenty of clean water for several minutes, lift eyelids to ensure thorough flushing, seek medical attention if discomfort persists
Ingestion: Rinse mouth, do not induce vomiting, seek medical evaluation if larger quantities ingested or symptoms develop
Most Important Symptoms: Mild irritation of eyes, mild gastrointestinal upset if ingested
Notes to Physician: Provide symptomatic treatment, no specific antidote known
Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide, water spray
Specific Hazards: May produce toxic fumes of carbon oxides upon combustion
Special Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear
Firefighting Precautions: Avoid inhalation of smoke, use water spray to cool exposed containers, contain firewater runoff
Explosion Risk: Low, not classified as explosive
Personal Precautions: Wear suitable gloves, goggles, and protective clothing, ensure adequate ventilation
Environmental Precautions: Prevent release to drains, surface water, or soil
Methods for Cleanup: Absorb spilled material with inert absorbents like sand or diatomaceous earth, collect in labeled containers for disposal, clean area with detergent and water
Spill Response: For small spills, use absorbent pads; for larger spills, dike area and pump material into salvage containers
Notification: Report significant releases or environmental contamination as required by local regulations
Handling: Avoid contact with eyes, prolonged or repeated skin exposure; use in well-ventilated areas; avoid aerosol or mist formation
Hygiene: Wash hands after handling, do not eat, drink, or smoke during use
Technical Measures: Use mechanical exhaust if mists are generated, keep containers closed when not in use
Storage: Store in original, tightly sealed containers away from incompatible materials like strong oxidizers; keep in cool, dry, well-ventilated area
Incompatibilities: Strong acids, bases, oxidizing agents
Shelf Life: Stable for at least 2 years under recommended storage
Engineering Controls: General room ventilation adequate in most cases; local exhaust recommended for operations producing mist
Respiratory Protection: Not usually needed under normal conditions; use NIOSH-approved respirator if airborne concentrations are excessive
Eye Protection: Safety glasses with side shields or chemical splash goggles
Skin Protection: Chemical-resistant gloves such as nitrile or neoprene; coveralls or protective clothing if splashing possible
Environmental Controls: Prevent material from entering drains, sewers, or waterways
Exposure Limits: No established occupational exposure limits for components
Appearance: Clear to pale yellow liquid
Odor: Faint, mild fatty odor
Odor Threshold: Not available
pH: Not applicable (insoluble in water)
Melting Point: Below -10°C
Boiling Point: >300°C (decomposes)
Flash Point: >200°C (Closed cup)
Evaporation Rate: Very low
Flammability: Not classified as flammable
Vapor Pressure: Negligible at room temperature
Vapor Density: Not determined
Relative Density: 0.94-0.96 g/cm³
Solubility: Insoluble in water, soluble in most organic solvents
Partition Coefficient (log Kow): 5–7 (estimated)
Viscosity: 25–35 mPa·s (at 20°C)
Chemical Stability: Stable under recommended conditions of use and storage
Reactivity: No hazardous reactions expected during normal handling
Conditions to Avoid: Excessive heat, open flame, strong oxidizing conditions
Materials to Avoid: Strong oxidizers, acids, bases
Hazardous Decomposition: Burning produces carbon monoxide, carbon dioxide, possible small amounts of acrolein or aldehydes
Polymerization: Will not occur
Acute Toxicity: Oral LD50 (rat) >5000 mg/kg; low toxicity, not expected to cause acute health effects
Skin Irritation: Practically non-irritating to most skin types; prolonged exposure may cause mild redness, dryness
Eye Irritation: May produce slight, transient discomfort
Inhalation: Not likely hazardous at room temperature; mists may cause throat irritation; no long-term data suggest chronic effects
Sensitization: Not expected to cause allergic skin reactions
Carcinogenicity: Not listed by IARC, NTP, or OSHA as carcinogenic
Mutagenicity: No evidence from available data
Reproductive Toxicity: No evidence of reproductive or developmental toxicity in animal studies with similar esters
Chronic Effects: None identified from existing safety data
Ecotoxicity: Low acute toxicity to aquatic organisms; LC50 (fish, 96h) >100 mg/L; not expected to bioaccumulate significantly
Persistence: Readily biodegradable in aerobic environments
Bioaccumulation: Potential is low due to rapid biodegradation
Mobility in Soil: Limited mobility, tends to adsorb to soil and sediment
Other Adverse Effects: Large spills may cause surface film which can impact oxygen transfer in water bodies; routine use poses minimal environmental risk
Product Disposal: Incineration in compliance with local regulations; small amounts may be absorbed to an inert matrix and landfilled where permitted
Contaminated Packaging: Empty containers should be triple-rinsed, punctured, and sent for recycling or disposal in certified waste facilities
