Supplier Identification: Manufacturer or distributor name, address, and emergency contact number required on package
Emergency Phone: Contact number for poison center or company emergency service
Classification: Not classified as hazardous under GHS criteria; can be a mild irritant
Hazard Statements: May cause mild eye or skin irritation after prolonged or repeated exposure; dust may cause respiratory tract irritation
Pictograms: Not typically required, but operator should consider dust mask and gloves
Signal Word: None required
Precautionary Statements: Avoid creating and breathing dust; wash hands after handling; ensure adequate ventilation; keep away from those with sensitive skin or respiratory conditions
Chemical: Sodium Stearate
CAS Number: 822-16-2
Concentration: 95-100%
Impurities: Minor amounts of water, fatty acids, sodium chloride, or other stearates may be present from manufacturing
Eye Contact: Rinse gently with water for at least fifteen minutes, remove contact lenses, seek medical help if irritation persists
Skin Contact: Wash area with soap and water; discontinue use if redness or swelling develops
Inhalation: Move to fresh air, seek medical attention if coughing or breathing difficulty continues
Ingestion: Rinse mouth, do not induce vomiting; give water if alert; seek medical attention for discomfort
Suitable Extinguishing Media: Water spray, alcohol-resistant foam, dry chemical, carbon dioxide
Specific Hazards: When heated, can emit acrid smoke and carbon oxides
Special Protective Equipment: Firefighters need self-contained breathing apparatus and protective clothing
Advice for Firefighters: Cool containers exposed to fire with water spray; avoid inhalation of combustion products
Personal Precautions: Avoid dust formation; wear dust mask, gloves, goggles, and protective clothing
Environmental Precautions: Prevent powder from entering surface water and drains
Methods for Cleanup: Sweep up and place in appropriate containers for disposal; ventilate area; avoid generating dusty clouds; wash spill area with water after collection
Handling: Work in well-ventilated spaces; use mechanical ventilation if dust levels rise; handle with clean, dry tools; avoid contact with eyes and skin
Storage: Store in tightly sealed containers, away from moisture and heat sources; keep far from incompatible materials like strong acids and oxidizers; label containers clearly; ensure only trained personnel have routine access
Exposure Limits: No established OSHA PEL or ACGIH TLV
Engineering Controls: Local exhaust ventilation limits airborne dust
Personal Protective Equipment: Wear safety goggles, gloves, dust mask or respirator if dust is generated, and protective work clothing
Hygiene Measures: Wash hands and exposed skin before eating or drinking and after handling
Appearance: White, powdery solid or flakes
Odor: Slightly fatty, characteristic odor
Melting Point: About 245°C (473°F)
Boiling Point: Decomposes before boiling
Solubility: Soluble in water at elevated temperatures, forms milky dispersions at room temperature
Density: 0.5–0.7 g/cm³ (bulk)
pH (10% solution): 9–10.5
Vapor Pressure: Not volatile
Other Data: Not combustible, not explosive under normal conditions; flash point not applicable
Chemical Stability: Stable under recommended storage and handling conditions
Reactivity: Non-reactive with most materials
Incompatible Materials: Strong acids release stearic acid, strong oxidizers may cause combustion
Hazardous Decomposition: Produces carbon monoxide and dioxide, possibly irritating smoke on thermal decomposition
Conditions to Avoid: Avoid excess heat, humidity, and sources of ignition
Acute Toxicity: Low toxicity by oral or dermal exposure; no long-term data indicates carcinogenicity
Eye Contact: May cause mild irritation or redness, especially as powder
Skin Contact: Slight irritation possible after repeated or prolonged exposure
Inhalation: Large amounts of dust may irritate respiratory tract, especially in sensitive individuals or those with asthma history
Ingestion: Not expected to cause significant adverse effects at small volumes
Chronic Exposure: No scientific evidence links sodium stearate to serious chronic illnesses
Toxicity to Aquatic Life: Considered low; high concentrations can affect aquatic organisms by surfactant action, possibly causing foaming
Persistence and Degradability: Readily biodegradable by environmental microbes
Bioaccumulative Potential: Not likely to accumulate in the food chain
Mobility in Soil: Limited, binds to particulate matter
Other Adverse Effects: Minimal impact on environment if proper disposal is followed
Waste Disposal: Collect unused or waste sodium stearate and place in sealed, labeled containers for disposal in accordance with local, state, and federal regulations
Contaminated Packaging: Triple-rinse, then dispose as non-hazardous waste or recycle if possible
Environmental Precautions: Avoid discharge to natural waters and sewer systems
UN Number: Not classified as a hazardous material
