Chemical Name: Decanoic Acid
Other Names: Capric acid
Chemical Formula: C10H20O2
CAS Number: 334-48-5
Appearance: White to pale yellow crystalline solid
Odor: Slightly unpleasant, fatty odor
Common Uses: Additive in perfumes, manufacture of esters, plasticizers, lubricants, food flavoring, and surfactants
Classification: Irritant to skin and eyes
Physical Hazards: Possible combustible dust hazard in solid form
Health Hazards: Skin irritation, eye irritation, mild respiratory tract irritation upon inhalation of dust or vapor
Environmental Hazards: Possible aquatic toxicity with large spills
Substance: Decanoic Acid (pure or technical grade)
Purity: Typically greater than 95%
Impurities: Minor fractions of related fatty acids
Main Ingredient: Decanoic Acid
Inhalation: Move to fresh air, seek medical attention if symptoms like coughing or shortness of breath persist
Skin Contact: Wash affected area with plenty of water and mild soap, remove contaminated clothing
Eye Contact: Rinse immediately and carefully with plenty of water for at least 15 minutes, seek medical help if pain or irritation persists
Ingestion: Rinse mouth with water; do not induce vomiting; consult a physician if a significant amount has been swallowed
Suitable Extinguishing Media: Foam, dry chemical powder, carbon dioxide, or water spray
Hazardous Combustion Products: May release acrid smoke, carbon monoxide, carbon dioxide when burning
Special Equipment: Use self-contained breathing apparatus and full protective gear
Fire Hazards: Solid and vapors can catch fire; dust may present explosion risk if dispersed in air in confined spaces
Personal Precautions: Use gloves and eye protection, prevent breathing dust
Spill Response: Collect solid spills by sweeping or vacuuming with equipment fitted for combustible dusts; for liquids, absorb with inert material like sand, place in waste container
Environmental Precautions: Prevent large quantities from entering sewers or waterways
Decontamination: Wash area with water and detergent after bulk removal
Handling: Wear protective clothing, avoid contact with eyes and skin, prevent formation of dust clouds
Storage: Keep containers tightly closed, store in cool, dry, well-ventilated areas away from sources of ignition or materials like strong oxidizers
Segregation: Store away from food and feedstuffs
Personal Protective Equipment (PPE): Chemical-resistant gloves, safety goggles or face shield, protective clothing
Ventilation: Use local exhaust ventilation if dust or mists are generated
Respiratory Protection: Mask or respirator if dust is high or ventilation is inadequate
Hygiene Measures: Wash hands thoroughly after handling, do not eat or smoke during use
Physical State: Solid at room temperature
Melting Point: About 31 to 32°C
Boiling Point: About 268°C
Density: 0.89 g/cm³ at 20°C
Solubility: Practically insoluble in water; soluble in ethanol, ether, and many organic solvents
Vapor Pressure: Very low at room temperature
pH: Not applicable for solid
Odor Threshold: Detectable at low concentrations, may impart a faintly rancid, fatty smell
Chemical Stability: Remains stable under normal storage and handling conditions
Conditions to Avoid: Exposure to strong heat, open flame, and incompatible chemicals
Incompatible Materials: Strong oxidizers such as peroxides, acids, bases, and reducing agents
Hazardous Decomposition: Releases carbon oxides and possibly toxic fumes when burned or decomposed at high temperatures
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Effects: May cause mild to moderate irritation of eyes; can irritate skin after prolonged or repeated contact; high concentrations of dust or fumes may bother the respiratory tract
Chronic Effects: There are no well-established long-term effects from occupational exposure in most handling scenarios
Carcinogenicity: Not classified as carcinogenic based on available scientific studies
Mutagenicity: Current data do not strongly indicate mutagenic effects
Sensitization: Reports of allergic reactions are rare; patch testing recommended for sensitive individuals
Ecotoxicity: May be harmful to aquatic life in high concentrations; limited data suggest low bioaccumulation and moderate biodegradability
Mobility: Tends not to migrate rapidly in soil due to low solubility
Persistence and Degradability: Expected to break down biologically in the environment over time
Potential for Bioaccumulation: Low, based on fatty acid profile and water solubility characteristics
Disposal Methods: Collect in appropriate containers and deliver to approved chemical disposal facilities
Regulations: Follow all local, state, and national regulations for chemical waste
Packaging Disposal: Decontaminate any containers before recycling or disposal
Environmental Safety: Take care to avoid releases to the environment, particularly water sources
Shipping Classification: Not regulated as a dangerous good in small quantities by land, sea, or air
Precautions: Package securely to avoid puncture, crushing, and direct exposure
Labeling: Include clear identification on packaging
Bulk Transport: Ensure compatibility with other products being shipped
Occupational Regulations: Subject to workplace chemical safety standards in most industrialized countries
Environment Regulations: Listed as a substance requiring appropriate handling to avoid large releases into water or soil
Inventory Status: Registered in major chemical inventories such as TSCA and REACH
Worker Protection: Covered under general occupational health and safety rules for chemical exposure
Community Right-to-Know: In some jurisdictions, storage locations and quantities may be subject to public access reporting
