GHS Classification: Not classified as hazardous according to GHS criteria
Primary Hazard: Dust may cause mild mechanical irritation to eyes, skin, or respiratory system
Signal Word: None
Pictograms: None assigned
Potential Health Effects: Dust inhalation may trigger coughing or mild discomfort; skin or eye contact may result in short-lived irritation; swallowing large quantities can upset the gastrointestinal tract
Precautionary Statements: Wash hands after handling; avoid excessive dust generation; use adequate ventilation
Chemical Name: Aluminum Monostearate
Concentration: >90% by weight
Impurities: Minor fatty acid salts or aluminum compounds, typically under 5%
Chemical Family: Metal soap (aluminum salt of fatty acid)
Eye Contact: Rinse eyes with clean water for several minutes, holding eyelids apart; seek medical attention if discomfort persists
Skin Contact: Remove contaminated clothing; wash affected area with soap and water; seek medical advice if irritation develops
Inhalation: Move person to fresh air; get medical attention if breathing problems continue
Ingestion: Rinse mouth with water; do not induce vomiting unless directed by a medical professional; seek medical help for persistent symptoms
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, foam, or water spray
Unsuitable Extinguishing Media: Jet of water may spread dust
Specific Hazards: Burning produces fumes of carbon oxides and aluminum oxides
Protective Equipment: Firefighters should use self-contained breathing apparatus and protective clothing
Special Precautions: Control dust to reduce risk of explosive mixtures in air
Personal Precautions: Avoid inhaling dust; ventilate area; wear dust mask and safety goggles
Environmental Precautions: Prevent loose material from entering drains, surface, or groundwater
Containment: Scoop up material; place in container for proper disposal
Cleanup Methods: Use vacuum or wet sweeping to avoid dust generation; wash spill site with water after cleaning
Handling: Prevent formation of airborne dust; use protective equipment and ensure good ventilation; avoid contact with skin and eyes
Storage Conditions: Store in dry, cool, and well-ventilated place away from food and incompatible chemicals; keep containers tightly sealed
Incompatible Materials: Strong acids, alkalis, oxidizers
Storage Class: Chemical storage, non-combustible solids
Control Parameters: No specific occupational exposure limits for aluminum monostearate; use general limits for nuisance dust: 10 mg/m³ (inhalable), 3 mg/m³ (respirable)
Engineering Controls: Provide local exhaust ventilation where dust is generated; use general dilution ventilation in work area
Eye Protection: Safety goggles
Skin Protection: Wear chemical-resistant gloves and clean clothing
Respiratory Protection: Use particulate mask for dusty conditions
Hygiene Measures: Wash hands before eating, drinking, or smoking; launder clothing regularly if contamination occurs

Hazardous Decomposition: Carbon monoxide, carbon dioxide, aluminum oxides may form in fire or overheating
Acute Toxicity: Low oral and dermal toxicity reported for similar aluminum soaps
Skin Irritation: Mild irritation possible from prolonged or repeated contact
Eye Irritation: Mechanical irritation possible with high dust exposure
Inhalation Toxicity: Dust may irritate respiratory tract; chronic exposure to high levels uncommon, but can worsen existing airway problems
Sensitization: No evidence of sensitizing effects under normal use
Chronic Effects: Not classified as carcinogenic or mutagenic
Other Effects: No evidence of reproductive or developmental toxicity for aluminum monostearate itself
Aquatic Toxicity: Not considered hazardous to aquatic life in usual concentrations
Persistence and Degradability: Components may partly biodegrade in water or soil over time
Bioaccumulative Potential: Low, due to limited solubility in water
Mobility in Soil: Tends to remain in soil or sediment due to insolubility
Other Ecological Data: Reducing dust spread and materials entering water systems can limit impact on local ecosystems
