Hazard Symbols: None required for general food/feed grade
Signal Word: None assigned
Precautionary Statements: Avoid generating dust; use only in well-ventilated areas
Active Ingredient: Iron complexed with yeast cellular material
Typical Iron Content: 2% to 8% (by weight), usually as ferrous or ferric compounds
Carrier Matrix: Saccharomyces cerevisiae or other nutritional yeast strains
Impurities: Moisture 2–8%, protein 40–60%, trace minerals (zinc, copper, manganese)
Additives: May contain stabilizers or anti-caking agents depending on manufacturer
CAS Numbers: Not available due to mixture and biological content
Eye Contact: Rinse eyes with clean water for several minutes, seek medical attention if irritation persists
Skin Contact: Remove contaminated clothing, wash skin with plenty of soap and water
Inhalation: Move to fresh air, seek medical support if respiratory symptoms develop
Ingestion: Rinse mouth, drink water; contact medical services in case of large ingestion or if symptoms arise
Most Important Symptoms: Mild irritation, nausea in susceptible persons after excessive exposure
Special Notes for Physicians: Supportive treatment, monitor for iron toxicity with high ingestion
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, water spray
Unsuitable Extinguishing Media: Direct water stream may scatter powdered material
Combustion Hazards: Product itself is generally non-combustible, but organic constituents may burn at high temperatures
Special Protective Equipment: Firefighters should use self-contained breathing apparatus for particulate or smoke
Hazardous Combustion Products: Iron oxides, carbon dioxide, and traces of carbon monoxide if burned
Special Procedures: Cool exposed containers with water spray, avoid inhaling combustion fumes
Personal Precautions: Avoid dust formation; use dust mask and protective eyewear
Environmental Precautions: Prevent large amounts from entering water systems, avoid unnecessary spillage
Method of Clean-Up: Sweep or vacuum up material, place into suitable container for reuse or disposal
Disposal of Residues: Wash contaminated area with water, prevent dust dispersal
Safe Handling: Handle in a clean, ventilated area; minimize generation of airborne particles
Hygiene Practices: Wash hands after use, remove dust from work clothes
Storage Requirements: Store in dry, cool area away from moisture and strong oxidizers
Shelflife: Typically 12–24 months unopened at ambient temperature
Incompatible Materials: Strong acids, strong bases, and oxidizers can react with contents
Packaging: Use sealed bags, drums, or containers to prevent contamination and caking
Engineering Controls: Local exhaust ventilation or fume hood to control dust
Personal Protection: Use safety glasses, dust mask (NIOSH N95 or equivalent) for bulk handling, gloves for sensitive skin
Occupational Exposure Limits: No specific limits set for mixture; iron dust TLV (ACGIH): 1 mg/m³ as Fe (respirable fraction)
General Protection: No eating, drinking, or smoking during handling; avoid contamination of work surfaces
Monitoring Methods: Air monitoring in facilities handling tonnage quantities, routine checks for respirable dust
Appearance: Light to dark brown or tan free-flowing powder, may appear granular
Odor: Slightly yeasty, mild and non-offensive
Melting Point: Not applicable (decomposes before melting)
Solubility: Partially soluble in water, disperses to form suspension
pH (1% solution): Neutral to slightly acidic (pH 5.0–7.5)
Bulk Density: 0.3–0.6 g/cm³ depending on granulation
Flash Point: Not relevant for standard handling
Decomposition Temperature: Organic decomposition above 160°C
Particle Size: Fines to medium granules
Vapor Pressure: Not volatile
Chemical Stability: Stable under normal ambient conditions
Reactivity: Minimal with most substances under storage and use conditions
Conditions to Avoid: Prolonged exposure to high humidity, contact with strong oxidants
Hazardous Reactions: None reported in standard feed or food settings
Decomposition Products: Iron oxides, water vapor, trace gases on burning or decomposition
Polymerization: Not applicable
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Toxicity: Not acutely toxic in recommended uses; excessive ingestion may pose risk of iron toxicity, especially in children
Chronic Toxicity: Overconsumption may contribute to iron accumulation; long-term industrial inhalation might lead to lung irritation
Known Effects: Nausea, gastrointestinal discomfort, irritant to mucous membranes possible
Sensitization: No widespread reports of allergic or sensitizing effects
Carcinogenicity: No evidence for carcinogenicity in humans (IARC: Not classifiable for yeast and iron preparations in this form)
Mutagenicity: Not known to cause mutations in current food/feed use levels
Ecotoxicology: Large releases may alter aquatic microbial balance if organically loaded waters receive high quantities
Persistence and Degradation: Yeast matrix is biodegradable; iron cycles through soil rebinding and plant uptake
Bioaccumulation: Little potential, iron is an essential mineral; no persistent organic pollutant properties
Transport in Environment: May adhere to sediment and undergo natural breakdown
Toxicity to Aquatic Life: No acute aquatic toxicity expected in typical accidental spills, but chronic iron loading can promote algal growth
Effect on Soil: Minimal, may slightly boost soil iron if repeatedly spilled
Waste Disposal Methods: Dispose as non-hazardous food or feed-grade material in accordance with local authority requirements
Container Disposal: Clean, empty containers can be recycled or disposed as solid waste
Restrictions: Avoid disposing in water bodies or drains to prevent nutrient loading
Best Practices: Composting with non-contaminated food waste or use as agricultural amendment if permissible
UN Number: Not regulated for transport
