Synonyms: Iron(II) glycinate, Iron bisglycinate
Recommended Use: Nutritional supplement, food additive, feed additive
Supplier: Contact details available on product packaging
Emergency Contact: National Poison Control, local first response numbers, or site safety officer
Intended Users: Laboratory personnel, production staff, transportation and storage handlers, quality assurance workers
Physical Hazards: Low fire hazard in powder form; dust can create air-suspended explosions under strong ignition
Health Hazards: May cause irritation to respiratory tract, eyes and skin; ingestion of large amounts may result in iron poisoning symptoms, including nausea, vomiting, abdominal pain
GHS Classification: Acute Oral Toxicity (Category 4), Eye Irritation (Category 2B)
Signal Word: Warning
Hazard Statements: Harmful if swallowed, causes eye and skin irritation
Precautionary Statements: Wash hands after handling, avoid breathing dust, wear protective equipment, avoid contact with eyes and skin
Chemical Name: Ferrous Glycinate
Concentration: 98-100%
Impurities: May contain trace mineral salts or unreacted precursors (glycine, iron salts); levels vary by manufacturer
Molecular Weight: 203.96 g/mol
Inhalation: Move to fresh air. Seek medical attention if symptoms such as shortness of breath or cough develop.
Skin Contact: Remove contaminated clothing and wash affected area with soap and water. Get medical attention if irritation persists.
Eye Contact: Rinse with plenty of water for 15 minutes lifting eyelids occasionally; seek prompt medical advice if irritation or vision changes occur.
Ingestion: Rinse mouth. Do not induce vomiting. Provide water to drink. Seek immediate medical help to assess risk of iron overdose.
Suitable Extinguishing Media: Use dry chemical, carbon dioxide, water spray, or foam depending on surrounding fire; avoid high-pressure water jets
Specific Hazards: Product itself doesn't burn, but dust can ignite and produce toxic fumes including oxides of carbon and nitrogen
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear
Firefighting Instructions: Move containers away from fire if safe; prevent fire-fighting runoff from entering water systems
Personal Precautions: Evacuate non-essential personnel; ventilate areas; minimize dust generation
Personal Protective Equipment: Gloves, dust mask or respirator, safety goggles and coveralls
Spill Cleanup: Sweep or vacuum up product using methods that don’t generate dust. Place in properly labelled container for disposal.
Environmental Precautions: Prevent run-off into drains and surface waters; notify authorities if spillage contaminates water bodies
Handling: Use only in well-ventilated areas; avoid dust formation; handle with appropriate protection; wash thoroughly after handling
Storage Conditions: Store tightly closed in a cool, dry, well-ventilated place; keep away from incompatible substances (strong oxidizers); store away from moisture and food
Special Handling Instructions: Avoid inhalation of dust, ingestion, and eye/skin contact; keep storage area clean, free of incompatible materials, and clearly labelled; use local exhaust ventilation in work areas
Occupational Exposure Limits: No established exposure limit for ferrous glycinate as a compound; observe general dust limits: OSHA PEL for nuisance dusts (15 mg/m³ total, 5 mg/m³ respirable, 8hr TWA)
Engineering Controls: Local exhaust ventilation, dust collection systems to reduce airborne concentrations
Personal Protection: NIOSH-approved dust respirator, chemical-resistant gloves (nitrile or rubber), safety goggles, lab coat or protective clothing
Hygienic Measures: Remove contaminated clothing quickly; wash hands before breaks, after handling, and before eating or drinking
Appearance: Light yellow to beige powder
Odor: Faint, typical amino acid
Odor Threshold: Not available
pH (1% solution): 3.5–7.0
Melting Point: Decomposes before melting
Boiling Point: Not applicable (solid)
Flash Point: Not flammable
Solubility in Water: Soluble
Vapor Pressure: Not applicable
Density: ~1.8–2.1 g/cm³
Partition Coefficient (n-octanol/water): Not determined
Decomposition Temperature: >200°C
Chemical Stability: Stable under standard ambient conditions; sensitive to moisture
Reactivity: Reacts with strong oxidizers or acids
Hazardous Reactions: Formation of toxic gases under fire conditions (carbon oxides, nitrogen oxides, iron oxides)
Conditions to Avoid: High humidity, elevated temperatures, contact with incompatible substances
Incompatible Materials: Strong oxidizing agents, mineral acids
Decomposition Products: Carbon monoxide, carbon dioxide, nitrogen oxides, iron oxides
Acute Toxicity: Limited data; based on compositions, estimated oral LD50 for rats is >300 mg/kg
Inhalation: May cause respiratory tract irritation; chronic exposure uncommon
Skin Contact: Mild to moderate irritation possible; not a known skin sensitizer
Eye Contact: May cause temporary irritation, redness, tearing
Ingestion: Risk of iron toxicity in significant overdose (liver, gastrointestinal damage, metabolic acidosis); gastrointestinal distress possible at lower doses
Chronic Effects: Prolonged exposure to excessive levels of iron can lead to hemosiderosis or organ damage in sensitive populations
Carcinogenicity/Mutagenicity: Not classified as carcinogenic; not expected to cause genetic damage
Reproductive/Developmental Toxicity: Not known to cause reproductive harm
Ecotoxicology: Not classified as dangerous for the environment; may cause local increases in bioavailable iron, contributing to eutrophication in some systems
Aquatic Toxicity: Not acutely toxic at predicted concentrations for regular usage; data lacking on chronic effects to aquatic invertebrates and algae
Persistence/Degradability: Expected to be biodegradable over time; degradation products include inorganic iron salts and amino acids
Bioaccumulation: Not expected to bioaccumulate
Mobility in Soil: Product is soluble and may leach in wet soils; iron typically binds to soil particles, reducing risk of ground water contamination
Waste Treatment Methods: Dispose of according to local, regional and national regulations; consult waste disposal authority for guidance
Product Disposal: Unused product and contaminated packaging should be collected and sent to approved disposal or recycling facility; never pour into waterways or public sewer systems
Container Handling: Containers should be emptied completely, rinsed, and recycled or disposed as hazardous waste if contaminated
Special Precautions: Do not attempt burning; avoid creating dust during transfer to waste containers
UN Number: Not applicable (not classified as a hazardous material under most transport regulations)
UN Proper Shipping Name: Not regulated
Transport Hazard Class: Not classified as dangerous
Packing Group: Not regulated
