Chemical name: Dibutyl Sebacate
CAS number: 109-43-3
Common uses: Plasticizer in polymers, lubricant, solvent for flavors and fragrances
Molecular formula: C18H34O4
Physical form: Colorless to pale yellow oily liquid
Classification: Not considered hazardous under normal conditions
Principal hazards: May cause mild skin and eye irritation upon contact
Signal word: Warning for mild irritation potential
Route of exposure: Contact with skin, eyes, inhalation of mist or vapor, or ingestion
Possible symptoms: Redness on skin, stinging of the eyes, mild discomfort if inhaled at high vapor concentrations
Main ingredient: Dibutyl Sebacate at or near 100% by weight
Impurities: Trace levels of other esters or alcohols possible depending on manufacturing process, usually present at insignificant concentrations
Chemical family: Aliphatic dicarboxylic acid ester
Skin contact: Wash thoroughly with soap and water; persistent irritation may need medical attention
Eye contact: Rinse eyes with water for several minutes; see a healthcare provider if irritation continues
Inhalation: Move to fresh air if exposure causes discomfort; seek medical help for lingering effects
Ingestion: Rinse mouth, drink water, and consult a doctor if feeling unwell; do not induce vomiting unless directed by health professionals
Suitable extinguishing media: Use foam, dry powder, or carbon dioxide for small fires; water spray helps cool containers
Specific hazards: Combustible at high temperatures; thermal decomposition can create harmful vapors
Protective equipment: Firefighters need self-contained breathing apparatus and protective clothing to avoid inhaling fumes
Fire residues: Spilled or leaked liquid may create a slipping hazard in fire areas
Personal precautions: Prevent skin or eye contact by using gloves and goggles
Spill cleanup methods: Absorb with inert substances like sand, gather into leak-proof containers
Environmental precautions: Prevent from entering drains, watercourses, or soil; collect contaminated soil for safe disposal
Ventilation: Increase airflow in enclosed spaces to disperse vapors and reduce odor
Handling practices: Use with adequate ventilation, avoid direct contact; no eating or drinking during handling
Storage requirements: Store in closed, labeled containers away from heat sources and direct sunlight
Incompatibilities: Keep away from strong oxidizing agents and strong acids
Storage temperature: Keep within moderate ranges to avoid container rupture or degradation
Occupational limits: No specific regulatory exposure limits established; general workplace hygiene remains important
Personal protection equipment: Wear safety goggles, chemical-resistant gloves, and appropriate protective clothing during handling
Respiratory protection: Needed only if vapor or mist concentrations exceed comfort levels or in poorly ventilated spaces
Engineering controls: Good local exhaust and general room ventilation help minimize vapor buildup
Appearance: Clear to slightly yellow oil-like liquid
Odor: Faint, mildly oily odor
Boiling point: 344°C at atmospheric pressure
Melting point: Around -10°C
Density: About 1.05 g/cm³ at 20°C
Solubility: Practically insoluble in water, readily mixes with organic solvents
Vapor pressure: Low at ambient temperature
Flash point: Roughly 180°C (closed cup method); flammable at higher temperature
Chemical stability: Stable under normal storage and handling conditions
Reactivity: Does not react vigorously with most industrial materials
Hazardous decomposition: Combustion or extreme heat may release carbon monoxide, carbon dioxide, and other organic vapors
Conditions to avoid: Prolonged exposure to strong oxidizers, extremely high temperatures, or open flames
Acute toxicity: Low toxicity by oral, skin, or inhalation routes in laboratory testing
Chronic effects: No evidence of cumulative harm through routine occupational use
Skin irritation: Minor and reversible in most people; not considered a strong skin sensitizer
Eye effects: May cause mild, transient irritation if splashed in eyes
Carcinogenicity: Not classified as cancer-causing based on available evidence
Other risks: No evidence of reproductive or developmental toxicity in published safety reviews
Aquatic toxicity: Very low toxicity to fish and invertebrates at concentrations likely to be encountered in the environment
Degradability: Will eventually break down under environmental conditions; some persistence in water or soil is possible before full degradation
Bioaccumulation: Low potential for significant buildup in aquatic organisms
Spill concern: Large, repeated spills may harm aquatic habitats or disrupt soil organisms near point sources
Waste handling: Collect waste liquid and contaminated absorbents in suitable containers for transport to an approved disposal facility
Method: Prefer recycling or incineration at licensed locations; landfill only as last resort under local guidelines
Regulatory compliance: Follow all local laws and company policies for safe disposal and recordkeeping
Hazard class: Not typically regulated as a hazardous material for most common means of land and sea transport
Packing group: No special packaging beyond leak-proof, sealed containers
Labeling: Standard labels for chemical substances; not designated as dangerous for transit under most transport codes
International: Registered and accepted in many jurisdictions as a low-risk chemical
Workplace labeling: Chemical name, hazards, and safe handling notes must appear clearly on workplace containers
Inventory listing: Included on inventories such as TSCA, EINECS, and related national lists as a recognized chemical
Restrictions: Few restrictions on use outside of food or pharmaceutical applications, where stricter purity standards might apply
