Supplier Information: Contact details of manufacturer or distributor; address, phone, emergency contact
Emergency Phone: Company-specific emergency line for chemical incidents
Classification: Not classified as hazardous under GHS regulations
Label Elements: No signal word; precautionary statements focus primarily on handling, not ingestion or eye contact
Hazards: May irritate eyes or skin with prolonged contact; ingestion or inhalation not expected in normal use
Main Symptoms: Redness or mild discomfort at exposure site, especially eyes
Environmental Effects: Persistence and possible bioaccumulation, not immediately toxic to aquatic species at typical discharge levels
Emergency Overview: Colorless, oily liquid with mild odor; low toxicity, but handle to avoid unnecessary exposure
Chemical Name: Dioctyl Sebacate
CAS Number: 122-62-3
Concentration: >99%
Impurities: Sebacic acid esters (trace), possible stabilizers depending on supplier
Additives: None typical for pure grades used industrially; always check label
Mixture Status: Substance, not a mixture
Eye Contact: Flush immediately with plenty of water; remove contact lenses; seek medical advice if irritation persists
Skin Contact: Wash with soap and water; remove contaminated clothing; seek care for persistent redness
Inhalation: Move to fresh air; seek care if symptoms develop, though vapors are unlikely under normal temperatures because of low volatility
Ingestion: Rinse mouth gently; seek medical attention only if large amounts swallowed or symptoms appear
Notes for Medical Professionals: Treat based on symptoms; no specific antidote required
Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, foam
Unsuitable Media: Direct high-pressure water stream may spread liquid
Hazardous Combustion Products: Carbon dioxide, carbon monoxide, possibly sebacic acid derivatives
Special Protective Equipment: Self-contained breathing apparatus for fire-fighters, protective clothing to prevent skin contact
Fire-Fighting Instructions: Cool containers with water spray from safe distance; contain run-off to prevent environmental contamination
Flammability: Not highly flammable, high flash point above 210°C (410°F) reduces immediate fire concern under normal storage
Personal Protection: Wear gloves, eye protection, avoid inhalation or direct skin contact
Spill Response: Absorb with sand or inert material; scoop into suitable containers for disposal
Environmental Precautions: Prevent entry into waterways, soil, or drains
Cleanup Methods: Wash spill area with detergent and water; ventilate the area
Notification: Report significant spills to local authorities per regional regulations
Handling: Use with adequate ventilation; avoid contact with skin, eyes, and clothing; wash hands after use
Storage Conditions: Keep containers tightly closed in dry, cool, well-ventilated areas away from heat or open flames
Storage Temperature: Store between 15-30°C (59-86°F); avoid freezing or overheating
Incompatible Materials: Strong oxidizing agents, acids
Hygiene Practices: Regular cleaning of work areas; no eating, drinking, or smoking in handling areas to avoid ingestion
Exposure Limits: No specific national or international exposure limits suggested for DOS
Engineering Controls: Use local exhaust or general ventilation for bulk handling
Personal Protection: Gloves made of nitrile, neoprene, or similar; safety goggles; protective work clothing
Respiratory Protection: Not required for typical uses; use if vapor concentrations become high due to heating
Environmental Exposure Controls: All discharges managed per regulatory requirements to avoid aquatic release
Appearance: Colorless to pale yellow oily liquid
Odor: Mild, characteristic odor; not pungent or offensive
pH: Not applicable
Melting Point: −10°C (14°F)
Boiling Point: 250-400°C (482-752°F) at reduced pressure
Flash Point: >210°C (410°F) (closed cup)
Autoignition Temperature: Above 400°C (752°F)
Vapor Pressure: Negligible at ambient temperature
Density: About 0.91 g/cm³ at 20°C
Solubility: Insoluble in water; soluble in alcohols, ethers, and various organic solvents
Viscosity: 13-16 cSt at 40°C
Partition Coefficient (log Kow): 8.3 (estimated)
Chemical Stability: Stable under recommended conditions; no hazardous polymerization anticipated
Reactivity: Not reactive under normal circumstances
Hazardous Reactions: Could react with oxidizers to form irritating or toxic compounds
Conditions to Avoid: Excessive heat, open flames, sources of ignition
Materials to Avoid: Strong acids, bases, oxidizers
Decomposition Products: Carbon monoxide, carbon dioxide, sebacic acid on significant heating or burning
Acute Toxicity: Oral LD50 (rat): >10,000 mg/kg; low toxicity
Skin Corrosion/Irritation: Mild irritation possible with prolonged or repeated contact
Eye Damage/Irritation: Slight irritation possible
Inhalation: Not likely to present a hazard under normal use
Sensitization: Not known to cause skin sensitization based on animal studies
Chronic Toxicity: No evidence of mutagenic, carcinogenic, or reproductive toxicity in animal studies
Route of Exposure: Eyes, skin, accidental ingestion
Other Health Effects: Prolonged high-dose exposure not linked to systemic toxic effects in humans
Acute Aquatic Toxicity: Not acutely toxic to aquatic organisms at low concentrations
Persistence: Moderately persistent in soil and water
Bioaccumulation: Potential to accumulate in aquatic organisms due to hydrophobicity
Mobility: Low mobility in soil due to low water solubility
Biodegradability: Biodegradable over time by microorganisms
Aquatic Chronic Toxicity: Risk increases with continuous, uncontrolled discharge; regulatory attention focuses on persistent exposure only
Waste Disposal Methods: Send to licensed processor for incineration or proper chemical disposal per local, state, and national rules
Container Management: Empty containers fully before discarding; follow local recycling or disposal requirements
Sewage Disposal: Do not flush to drain or sewer to avoid aquatic exposure
Precautions: Avoid spills during transfer and handling; collect all waste into closed, labeled containers
