Precautionary Statements: Avoid dust formation, wash hands after handling, use in well-ventilated areas.
Hazard Symbol: None required given typical exposure scenarios in workplace and home settings.
Other Information: Dust may cause slight mechanical irritation to eyes or skin, rarely triggers allergy symptoms.
Substance: Calcium Citrate Anhydrous
Chemical Formula: Ca3(C6H5O7)2
Concentration: Product typically contains ≥97% active ingredient.
Impurities: Trace levels of related calcium salts and water not typically present in hazardous amounts.
Additives: No preservatives or chemical stabilizers added.
Inhalation: Move to fresh air, seek medical attention for ongoing symptoms such as coughing or wheezing.
Skin Contact: Wash with water and mild soap, remove contaminated clothing, seek care if redness or irritation develops.
Eye Contact: Flush with water for several minutes, keeping eyelids open with clean fingers, see medical provider if irritation persists.
Ingestion: Rinse mouth with water, drink plenty of fluids, seek medical care if nausea or discomfort continues for more than a few hours.
Most Important Symptoms: Irritation, redness, sneezing, sore throat.
Advice for Healthcare Providers: Symptomatic treatment and supportive care as required.
Suitable Extinguishing Media: Water spray, dry chemical, foam, or carbon dioxide appropriate for surrounding material.
Unsuitable Extinguishing Media: None identified for calcium citrate itself, but consider adjacent hazards.
Specific Hazards: Product does not burn or support combustion, thermal decomposition can release carbon oxides and calcium oxide.
Protective Equipment: Firefighters use self-contained breathing apparatus and protective clothing if dusts or decomposition fumes encountered.
Special Procedures: Remove containers from the area if possible and safe to do so.
Personal Precautions: Minimize dust generation, ventilate area, avoid inhalation and contact with skin or eyes.
Protective Equipment: Wear safety glasses, gloves, dust mask or respirator if dust exceeds workplace exposure limits.
Methods for Clean-up: Sweep up and place in properly labeled containers for reuse or waste disposal, use damp cloth to minimize airborne dust.
Environmental Precautions: Prevent large amounts from entering drains or waterways, collect spills to avoid contamination of soil and water.
Handling: Avoid creating or breathing dust, use in well-ventilated area, wear standard work gloves and eye protection during bulk processing.
Hygiene Measures: Wash hands thoroughly after use, avoid eating, drinking, or smoking during handling.
Storage: Store in cool, dry, well-ventilated area in tightly sealed containers, protect from moisture, keep away from incompatible substances like strong acids.
Incompatible Materials: Strong acids may cause release of citric acid and calcium salts, avoid contact.
Exposure Limits: Occupational exposure guidelines for nuisance dusts: ACGIH TLV (total particulate) 10 mg/m³; OSHA PEL 15 mg/m³.
Engineering Controls: Local exhaust ventilation or mechanical ventilation for dusty operations.
Personal Protective Equipment: Dust goggles for eye protection, gloves for skin protection, dust mask or respirator if exposure exceeds recommended limits.
Other Protective Measures: Wear protective clothing if handling large quantities, have eye-wash stations and hand-washing facilities available.
Appearance: White to off-white odorless powder.
Odor: No significant odor.
pH: Neutral to slightly alkaline (5% solution in water: pH 6-8).
Melting Point/Freezing Point: Decomposes at high temperature, does not melt.
Boiling Point: Not applicable, decomposes before boiling.
Solubility: Very slightly soluble in water; more soluble in ammonium salt solutions; insoluble in alcohol.
Vapor Pressure: Not volatile.
Density: Approximately 2.4 g/cm³.
Other Properties: Stable in normal conditions, forms dust easily if handled carelessly.
Chemical Stability: Remains stable under recommended storage and handling conditions.
Conditions to Avoid: Moist or humid environments, excessive heat, exposure to strong acids.
Incompatible Materials: Strong acids, strong oxidizers.
Hazardous Decomposition Products: Carbon dioxide, carbon monoxide, calcium oxide under strong heating.
Polymerization: Will not occur.
Acute Toxicity: No evidence of adverse effects in typical human exposures; oral LD50 (rat) estimated above 5000 mg/kg.
Chronic Effects: Long-term ingestion at high doses can cause hypercalcemia or gastrointestinal issues, otherwise considered low-risk.
Skin Contact: Minor irritation possible.
Eye Contact: Causes mechanical irritation, may lead to redness, tearing.
Inhalation: Dust may irritate respiratory tract.
Carcinogenicity: Not listed by NTP, IARC, or OSHA.
Mutagenicity: No data suggest genetic risk.
Reproductive Toxicity: No significant effects reported in standard toxicology reviews.
Ecotoxicity: Product contains minerals found naturally in soil, low risk to aquatic and terrestrial life in normal environmental releases.
Persistence and Degradability: Breaks down into natural mineral and organic acid forms.
Bioaccumulation: Low potential for bioaccumulation.
Mobility in Soil: Poor mobility, tends to remain at release site or bind to soil particles.
Other Effects: Large spills may temporarily increase water hardness, possibly impacting aquatic organisms in sensitive streams.
Safe Disposal Methods: Dispose as non-hazardous waste according to local, regional, or national guidelines; landfill or incineration as permitted.
Contaminated Packaging: Rinse empty containers thoroughly before recycling or disposal.
Special Precautions: Avoid dispersal of dust in air, prevent material from entering sewers or watercourses in significant amounts.
Other Considerations: Seek advice from certified waste contractors for disposal of bulk product or residues.
