Chemical Name: Iron(II) Lactate Hydrate
Common Use: This compound shows up in food fortification, animal nutrition, and as a laboratory reagent.
Appearance: Looks like a pale green, slightly granular powder. The hydrate form pulls in extra moisture.
Odor: Typically, there's no strong smell, but a faint earthy odor appears sometimes.
Molecular Formula: C6H10FeO6·xH2O
Molecular Weight: Based on hydration, typically about 253 g/mol.
Potential Health Effects: Breathing dust can irritate nose, mouth, or throat, sometimes making breathing rough if exposure lasts too long. Swallowing large amounts may lead to iron poisoning, showing up as nausea or abdominal pain. Iron compounds never treat a careless attitude lightly; misuse brings trouble.
Eye Irritation: Dust may sting or redden eyes.
Skin Contact: Prolonged exposure might cause minor irritation or redness.
Environmental Risks: Iron rarely creates disaster in small spills, but regular dumping upsets soil and aquatic habitats over time.
Hazard Pictograms: Not usually classified as hazardous under GHS, so no scary symbol, but precaution makes sense.
Precautionary Statements: Avoid inhaling dust, keep out of eyes, and avoid unnecessary contact with bare hands.
Main Ingredient: Ferrous lactate, hydrated
CAS Number: 5905-52-2
Purity: Often >90%, though trace amounts of other iron salts and lactic acid may tag along from production.
Inhalation: Move to open air, cough out the dust, relax, and sip water if throat feels rough.
Skin Contact: Wash away dust and residue with running water and mild soap. Dry well.
Eye Contact: Rinse gently under running water, taking time to blink and clear out grit.
Ingestion: Rinse mouth right away, drink water, and go seek medical advice if feeling faint, dizzy, or sick. Large amounts warrant immediate professional help.
Advice to Responders: Gloves, goggles, and organized thinking help more than panic.
Flammability: This salt refuses to burn, but containers still melt or burst if exposed to fire.
Suitable Extinguishing Media: Use water spray, dry chemical, or foam. Let old habits guide you—basic fire-fighting principles always serve. No unique hazards from its own properties.
Special Hazards: Thermal decomposition may release carbon oxides and iron fumes. Smoke inhalation never helps.
Protective Equipment: Wear standard firefighter gear—no shortcuts.
Surroundings: Remove containers from fire area if safe to do so.
Personal Precautions: Avoid creating clouds of dust, step back, and put on basic dust protection—dust mask, gloves, goggles.
Environmental Precautions: Sweep up without flushing down drains; iron salts feed algae in water bodies and upset balance.
Clean-up Methods: Shovel spills into strong containers, wipe surfaces with damp mop to catch stray powder, ventilate the area if possible.
Disposal: Collect for proper disposal instead of tossing in trash, as routine dumping in soil or water creates more harm than good.
Safe Handling: Minimize dust, use in ventilated space, and keep food and drink away from work area.
Avoiding Exposure: Wear gloves for frequent handling, follow hygiene basics—do not eat or smoke nearby.
Storage Conditions: Store in a dry, cool spot, seal containers tightly, and keep away from acids or oxidizers. Humidity causes caking and ruins consistency.
Incompatibilities: Iron salts react with strong acids—store apart from cleaners and peroxides.
Engineering Controls: Good local exhaust or regular fans cut down airborne dust. Keep work area tidy.
Eye Protection: Safety glasses with side shields work well.
Skin Protection: Gloves made of nitrile or latex handle most splashes and dust.
Respiratory Protection: Dust mask or respirator recommended when clouds can’t be avoided.
Work Practices: Wash up after handling, keep dusty clothes out of reach of food, and don’t bring powder home on your hands.
Physical State: Crystalline powder
Color: Pale green
Odor: Slight, earthy
Melting Point: Decomposes before melting
Solubility: Dissolves in water; gives a clear, greenish solution
pH in Solution: Typically neutral to slightly acidic
Vapor Pressure: Not volatile
Density: Around 1.8 – 2.0 g/cm³, varies with hydration
Other Properties: Caked lumps signal moisture exposure.
Chemical Stability: Stays stable in normal storage, but exposure to air and moisture creates clumping or slow oxidation.
Conditions to Avoid: Humid air, high temperatures, acids, and strong oxidizers.
Incompatible Materials: Strong acids, oxidizing agents like bleach.
Hazardous Decomposition: Upon strong heating, releases carbon oxides, iron dust, and sometimes acrid fumes.
Acute Toxicity: Effects depend on the dose. Large ingestion cases report symptoms of iron poisoning, including stomach pain, vomiting, and fatigue. Rare exposures cause more serious problems in young children.
Local Effects: The dust sometimes stings or dries out sensitive skin or eyes.
Chronic Effects: Regular, high exposure leads to excess iron in the body, putting strain on liver and other organs.
Routes of Exposure: Inhalation, ingestion, skin/eye contact all matter.
Carcinogenicity: There’s no indication that this iron compound causes cancer.
Ecotoxicity: Iron supports plant life in tiny doses, but high concentration patches around disposal areas mess up local water and soil chemistry.
Aquatic Impact: Fish suffer in water loaded with iron salts; algae blooms also become a problem.
Mobility in Soil: Iron binds strongly, but mobile forms reach water if spread too loosely.
Persistence: Iron stays in soil and water for ages, transforming chemically as it moves.
Safe Disposal: Package into sturdy, sealed containers and hand over to professional chemical disposal. Keeping it out of normal garbage and city drains prevents slow buildup in urban soils and waterways.
Recycling: Most small labs and workplaces can’t recover usable iron from waste, so safe disposal trumps reuse.
Legal Status: Some regions mark iron salts as regulated waste once dumped—local governments update these rules from time to time.
UN Classification: Not typically covered by hazardous goods transport regulations.
Labeling: Routine packaging, marked with product name, no major warnings.
Precautions: Seal containers to keep moisture out during shipping.
Spill Management: If the packaging leaks, sweep up and repackage, wash residue from floors, and caution against slipping.
GHS Status: Mostly unregulated, but workplace exposure rules still apply.
OSHA: Not specified as hazardous, but standard rules on handling chemicals still apply.
REACH, TSCA: Iron(II) lactate hydrate appears on several regional inventories, which means proper record-keeping stays important.
Worker Right-to-Know: Employees working with any iron salt benefit from access to clear instructions and hazard explanations.
Other Guidelines: Food-grade uses follow strict purity standards; all other uses focus on safe handling, storage, and disposal.
