Material Safety: An Honest Look at Dibutyl Adipate (DBA)

Identification

Name: Dibutyl Adipate
Chemical Formula: C14H26O4
Common Usage: Plastics, rubber, cosmetics, personal care
Physical State: Oily liquid
Color: Colorless to pale yellow
Odor: Mild, ester-like smell

Hazard Identification

Hazard Class: Not considered hazardous by common standards
Eye Contact: May cause slight irritation with exposure
Skin Contact: Not likely to cause significant irritation unless sensitivity exists
Inhalation: Low vapor pressure; inhaling high concentrations in mist or aerosol form can irritate the nose and throat
Ingestion: Little risk in small amounts, but consuming large quantities leads to stomach upset
Environmental Impact: Not a primary concern, but longterm buildup could disturb aquatic systems

Composition / Information on Ingredients

Active Ingredient: Dibutyl Adipate
Chemical Purity: Most commercial samples contain over 99% pure substance
Common Impurities: May include trace amounts of related adipates or butyl esters

First Aid Measures

Eye Exposure: Flush gently with water for several minutes, remove lenses if present
Skin Exposure: Wash off with soap and water, remove soiled clothing
Inhalation: Move to fresh air if discomfort occurs
Ingestion: Rinse mouth; if symptoms develop, get medical advice

Fire-Fighting Measures

Flash Point: About 180°C (open cup)
Explosion Risk: Does not explode under usual conditions
Fire-Fighting Media: Use dry chemical, foam, or carbon dioxide extinguishers
Combustion Hazards: Burning releases fumes like carbon oxides
Firefighting Tips: Firefighters should wear protective gear and avoid breathing smoke

Accidental Release Measures

Spill Cleanup: Absorb with inert material (like sand or earth), scoop in suitable container
Environmental Protection: Prevent entry into drains or bodies of water
Personal Precautions: Gloves and, if splash possible, eye protection
Ventilation: Keep area ventilated to avoid buildup of any mist

Handling and Storage

Handling: Avoid direct contact, minimize mist and vapor—use only in well-ventilated spaces
Storage: Store in tightly sealed container, away from flames or extreme heat
Temperature Needs: Keep above freezing to prevent thickening, away from sunlight
Containers: Metal or approved plastic work best for long-term storage

Exposure Controls and Personal Protection

Eye Protection: Goggles recommended during bulk handling or transfer
Hand Protection: Chemical-resistant gloves cut down on skin exposure
Respiratory: Mask needed only if working with splashes, mists or where good ventilation is lacking
Clothing: Standard workwear suits most roles
Workplace Controls: Local exhaust where large amounts are moved

Physical and Chemical Properties

Appearance: Clear, oily liquid
Odor: Faint, ester-like
Boiling Point: Around 340°C
Melting Point: About −50°C
Solubility: Negligible in water, mixes with most organic solvents
Density: Roughly 0.99 g/cm³
Vapor Pressure: Low enough not to cause issues at room temperature

Stability and Reactivity

Stability: Remains stable in sealed containers under normal use
Incompatibles: Strong acids, bases, and strong oxidizers speed up breakdown
Polymerization: Not expected under regular storage or use
Decomposition Products: High heat splits it into simple organic acids and volatile fumes

Toxicological Information

Acute Toxicity: Very low in animal studies
Chronic Effects: No proven major health issues from regular workplace exposure
Skin Sensitization: Occasional mild redness in sensitive folks
Carcinogenicity: No evidence connecting to cancer in available animal tests

Ecological Information

Aquatic Toxicity: Not highly toxic to fish or small aquatic life in diluted environmental concentrations
Biodegradability: Breaks down over days to weeks in water or soil
Bioaccumulation: Unlikely due to fast breakdown

Disposal Considerations

Waste Handling: Collect in sealed container for disposal rather than pouring down drains
Disposal Methods: Incineration under controlled conditions or use in chemical recycling streams where possible
Legal Disposal: Follow local and national rules about chemical waste

Transport Information

Transportation Hazard: Not regulated as hazardous for transport in most countries
Proper Shipping Name: Dibutyl Adipate
Packing Needs: Standard drums or bottles, leakproof and labeled

Regulatory Information

Occupational Exposure Limits: No strict levels set, but sensible exposure controls follow general good practice
Global Inventories: Registered in several major chemical inventories, including United States and Europe
Labeling: Standard labeling as a chemical, no special hazard icons required if sole ingredient
