Chemical Name: Octadecylacetamide
Common Name: Stearamide
Concentration: Typically 98-100% pure in commercial grade
Impurities: Minor amounts of fatty amide homologs present in some technical grades
Additives: None intentionally added
Inhalation: Remove person to fresh air; seek medical attention if symptoms such as coughing or shortness of breath persist
Skin Contact: Wash with soap and water; seek medical advice if irritation develops or does not improve
Eye Contact: Flush thoroughly with water for at least 15 minutes; remove contacts; seek medical help if irritation continues
Ingestion: Rinse mouth; seek medical attention if feeling unwell or if large quantities ingested
Most Important Symptoms: May irritate eyes, skin or respiratory tract due to dust exposure
Suitable Extinguishing Media: Dry chemical powder, foam, carbon dioxide, water spray
Unsuitable Media: Avoid direct water jets, which can spread a burning surface film
Hazardous Combustion Products: Forms carbon monoxide, carbon dioxide and nitrogen oxides in fire
Firefighting Instructions: Wear self-contained breathing apparatus and protective clothing; keep containers cool with water spray
Explosion Hazard: Dust from this material may form explosive mixtures in air; avoid open flames and sources of static discharge
Personal Precautions: Restrict unnecessary access, avoid contact, prevent dust formation, ventilate affected area
Protective Equipment: Use gloves, goggles, approved dust mask
Spill Cleanup: Sweep up material to avoid dust, collect in appropriate labeled container, dispose in accordance with regulations
Environmental Precautions: Prevent material from entering drains and surface water
Decontamination: Wash affected area with water after removal of material
Safe Handling: Minimize dust creation; use in well-ventilated areas; never eat, drink, or smoke while handling
Avoid: Static discharge, open flames, incompatible materials including strong oxidizers
Storage Conditions: Keep in tightly sealed containers, store in cool, dry and well-ventilated area
Incompatible Storage: Separate from oxidizing agents, acids, and strong bases
Occupational Exposure Limits: No established OSHA or ACGIH limits; recommended to follow good industrial hygiene practices
Engineering Controls: Apply local exhaust ventilation to reduce dust
Personal Protective Equipment: Safety glasses or goggles, chemical-resistant gloves, protective clothing to avoid skin exposure, particulate respirator in case of dust
Hygiene Practices: Wash hands after handling and before eating or drinking; remove and clean contaminated clothing before reuse
Physical State: Solid (waxy flakes or powder)
Color: White to off-white
Odor: Faint, fatty amine smell
Melting Point: 98–102°C (208–216°F)
Boiling Point: Decomposes before boiling
Solubility (Water): Insoluble
Solubility (Other): Soluble in hot alcohols, ether
Density: About 0.9 g/cm³ at 25°C
Flash Point: > 199°C (390°F)
Vapor Pressure: Negligible at room temperature
Partition Coefficient: log Kow estimated near 7
Chemical Stability: Stable at typical temperatures and pressures
Reactivity: Does not react with most materials under normal use conditions
Hazardous Polymerization: Will not occur
Conditions to Avoid: Heating above melting point, exposure to flames, sparks
Incompatible Materials: Strong acids, strong bases, oxidizing agents
Decomposition Products: Decomposes to carbon oxides, nitrogen oxides under excessive heating or fire
Routes of Exposure: Inhalation, ingestion, skin contact, eye contact
Acute Toxicity: Data shows low acute toxicity via oral and dermal exposure; estimated LD50 (oral, rat) > 5000 mg/kg
Chronic Effects: No evidence for chronic toxicity or carcinogenicity
Eye & Skin Irritation: Mild, transient irritation possible from physical contact, especially with dust
Sensitization: No evidence of skin sensitization in animal studies
Other Risks: No known mutagenic or reproductive risks
Aquatic Toxicity: Not expected to be acutely harmful to aquatic organisms; very low water solubility
Persistence and Degradability: Expected to be persistent due to low biodegradability
Bioaccumulative Potential: High log Kow suggests potential for bioaccumulation in aquatic species
Mobility in Soil: Low mobility; binds readily to organic soil matter
Other Adverse Effects: Keep out of waterways and storm drains whenever possible
Waste Treatment: Dispose as non-hazardous industrial waste if local regulations allow
Container Disposal: Rinse containers before recycling or disposal; follow local regulations
Do Not: Discharge into sewer systems, natural water flows, or unapproved disposal sites
Recommended Disposal Method: Controlled incineration or landfill in accordance with official guidance
UN Number: Not regulated for transport
DOT Classification: Not regulated
IMDG / IATA: Not regulated as dangerous goods
Special Precautions: Avoid shipment with incompatible chemicals such as strong oxidizers; use sealed containers to minimize release of dust
OSHA Status: Not classified as a hazardous chemical
TSCA Inventory: Listed
REACH Status: Exempted or registered as a phase-in substance
SARA Title III: Not listed as a hazardous or extremely hazardous substance
California Prop 65: Not on Proposition 65 list
