Chemical Name: Octadecylamine (1-Octadecanamine)
Synonyms: Stearylamine
CAS Number: 124-30-1
Purity: ≥ 98%
Impurities: Minor impurities below 2% may include shorter or longer chain amines or unreacted fatty acids
Other Ingredients: None that influence toxicity significantly at high purity
Inhalation: Remove person to fresh air. If breathing feels difficult, medical attention is strongly recommended as soon as possible.
Skin Contact: Flush skin with large amounts of water for at least fifteen minutes. Remove contaminated clothing. Chemical burns on the skin require urgent medical evaluation.
Eye Contact: Immediately rinse eyes with water for a minimum of fifteen minutes while holding eyelids open. Do not wait before seeking an emergency medical examination.
Ingestion: Rinse mouth with clean water, never induce vomiting. Give water to conscious person. Immediate contact with a medical professional is necessary for anyone who swallows this material.
Important Notes for Doctors: Treat symptoms and support airway management. Avoid gastric lavage if corrosive injury is suspected. Burns should be managed as chemical burns, especially in the mouth, esophagus, and stomach.
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, or water spray for larger fires. Avoid straight water streams on pool fires.
Hazards from Combustion: Burning produces toxic fumes including nitrogen oxides, ammonia, hydrocarbons. Vapors may irritate respiratory tract.
Protective Equipment for Firefighters: Self-contained breathing apparatus and full protective gear should be worn.
Detailed Instructions: Move intact containers away from flames if safe to do so. Cool containers with spraying water to prevent rupture from heat. Control runoff and avoid contamination of sewers or waterways due to aquatic toxicity. Contaminated fire extinguishing water must be collected separately.
Personal Precautions: Use chemical-resistant gloves, splash goggles, and protective clothing. Avoid inhalation or direct skin contact.
Environmental Precautions: Contain spills as materials are highly toxic to aquatic systems. Prevent release to watercourses and drains.
Cleanup Methods: Absorb with inert material (sand, earth, vermiculite). Collect in chemical waste containers. Ventilate the area. Do not touch spilled material without proper protection.
Disposal: Place absorbed waste in sealed, labeled drums for proper disposal by licensed chemical waste facility. Clean contaminated area thoroughly.
Safe Handling: Use in well-ventilated areas. Wear designated personal protective equipment. Keep away from open flames, sparks, and sources of statics. Do not breathe dust, fumes, or vapors.
Storage Conditions: Store in cool, dry location, away from direct sunlight, oxidizers, acids, and food items. Keep container tightly closed when not in use.
Special Precautions: Ensure containers remain upright and secure. Store only in corrosion-resistant containers that are labeled correctly to prevent accidental mixing or confusion.
Incompatible Materials: Avoid contact with strong acids, oxidizers, and materials that can react with amines.
Recommended Shelf Life: Use within designated shelf period provided by manufacturer for best performance and safety.
Occupational Exposure Limits: No specific national exposure limit established. Use general dust, mist, or vapor limits as workplace guidelines.
Engineering Controls: Use local exhaust or general ventilation to limit airborne concentrations.
Personal Protective Equipment: Chemical splash goggles, nitrile or butyl rubber gloves, long-sleeve protective clothing or coveralls. Use organic vapor respirators for high exposure tasks.
Hygiene Measures: Wash hands and exposed skin after use. Remove contaminated clothing and launder before reuse.
Monitoring Procedures: Regular air sampling in production environments gives early warning for exposure spikes.
Appearance: Waxy solid with pale yellow to white color
Odor: Amine-like, fishy
Molecular Weight: 269.5 g/mol
Melting Point: 49–54 °C
Boiling Point: 349 °C
Flash Point: 160 °C (closed cup)
Solubility: Insoluble in water, soluble in organic solvents (alcohol, ether)
Vapor Pressure: 1 mmHg at 135 °C
Density: 0.8 g/cm³ at 20 °C
pH: Strongly alkaline
Partition Coefficient (log Kow): 7.36
Chemical Stability: Stable under normal temperatures and recommended handling.
Conditions to Avoid: Excess moisture, heat above melting point, exposure to light for extended periods.
Reactivity: Reacts violently with strong acids producing heat and toxic fumes. Can react with oxidizers causing fire or explosion risk.
Hazardous Decomposition Products: Nitrogen oxides, ammonia, carbon monoxide, hydrocarbons, and potentially irritating vapors or gases on thermal decomposition
Polymerization: Not known to polymerize under normal storage and handling.
Acute Toxicity: Oral LD50 (rat): 560 mg/kg. Inhalation or dermal exposures can cause immediate irritation, burns, and systemic effects.
Skin Corrosion/Irritation: Produces burns, redness, pain, possible blisters if left untreated.
Eye Damage/Irritation: Causes serious irritation or burn—potential irreversible injury.
Respiratory Sensitization: Vapors and dust can irritate respiratory tract and mucous membranes.
Chronic Effects: Prolonged exposure may cause dermatitis, lung effects, or other allergic reactions.
Carcinogenicity: No evidence shows carcinogenic action in available studies.
Reproductive Toxicity: No conclusive animal or human data for reproductive toxicity at common workplace levels.
Symptoms after Exposure: Burning pain, coughing, headache, nausea, dizziness, loss of coordination, and chemical burns.
Ecotoxicity: Very toxic to aquatic life, including fish and invertebrates. Even small spills into natural waters have outsized consequences.
Persistence and Degradability: Slow degradation in aquatic environments. Binds to sediments due to high lipophilicity.
Bioaccumulative Potential: High. Tends to accumulate in aquatic organisms and food chains.
Mobility in Soil: Low. Binds strongly to soil; limited movement in groundwater.
Additional Notes: Prevent entry into sewers, waterways, or soil. Spilled product poses long-term risk to fish and other wildlife.
Waste Disposal: Collect product waste in labeled containers. Use licensed chemical waste contractors to incinerate or dispose by high-temperature thermal treatment.
Container Disposal: Empty containers contain residue and should be triple rinsed, punctured, and sent for recycling or disposal following hazardous waste protocols.
Hazardous Waste Codes: Use appropriate state or local hazardous waste classification. Do not allow product or rinsate to reach drainage systems.
Special Handling: Handle waste in accordance with local, regional, and national regulations. No landfill disposal for bulk product.
