Product: Calcium Acetate
Chemical Formula: C4H6CaO4
CAS Number: 62-54-4
Common Uses: Applied as a food additive, stabilizer, and in pharmaceuticals for managing phosphate levels in kidney disease; also used in laboratories and for wastewater treatment.
Hazard Class: Often considered nonhazardous, but large exposures bring issues.
Acute Health Risk: Inhalation or ingestion of high doses leads to minor mucus membrane irritation, nausea, or vomiting.
Reactivity Risk: Reacts with strong acids, producing acetic acid fumes.
Environmental Hazard: Large spills may locally alter pH in aquatic environments.
Main Ingredient: Calcium Acetate, nearly pure in most grades.
Impurities: Commonly low, trace minerals from manufacturing process.
Physical Form: White, odorless powder or granules, freely soluble in water.
Inhalation: Move outside, give fresh air, monitor for cough or discomfort.
Skin Contact: Wash thoroughly with soap and water; rinse continued exposure.
Eye Contact: Rinse with water, remove contacts if safe, see medical attention if irritation persists.
Ingestion: Rinse mouth, drink water; seek medical advice for chronic or intentional consumption.
Flammability: Not highly flammable on its own, but dust can burn.
Suitable Extinguishing Media: Use water spray, dry chemical, or foam for surrounding fires.
Special Protective Equipment: Wear self-contained breathing apparatus to avoid acetic acid byproducts.
Hazardous Byproducts: Heating above decomposition brings acetic acid fumes.
Personal Precautions: Use gloves, avoid breathing dust.
Environmental Precautions: Prevent large quantities from entering waterways to avoid local pH changes.
Cleanup Methods: Sweep up gently, avoid creating fine dust, store materials in sealed containers for disposal.
Handling: Work in well-ventilated areas, keep powder away from incompatible chemicals (especially strong acids).
Storage: Keep containers tightly closed, store dry and cool.
Incompatible Materials: Strong acids, moisture accelerates hydrolysis and cake formation.
Engineering Controls: Local exhaust for regular industrial handling.
Personal Protection: Respirator masks for employees handling bulk powder; eye protection; rubber gloves.
Exposure Limits: No strict occupational exposure limits documented, but minimize inhalation and skin contact.
Appearance: White powder or granules.
Odor: Odorless
Solubility: Readily dissolves in water.
Melting Point: 160°C (decomposition begins)
Boiling Point: Not applicable; decomposes before boiling.
Density: Roughly 1.5 g/cm³
pH (solution): Mildly alkaline (7-9 for 5% aqueous solution)
Chemical Stability: Stable under normal dry storage.
Hazardous Reactions: Contact with strong acids liberates acetic acid vapor.
Thermal Decomposition: Produces acetic acid, calcium oxide, and carbon dioxide if overheated.
Incompatible Substances: Strong acids, some oxidizers.
Acute Effects: Swallowing large amounts brings gastrointestinal distress, nausea, and vomiting.
Chronic Exposure: Not known to build up in the body, but repeated poor handling may cause mild respiratory irritation.
Carcinogenicity: Not classified as a carcinogen by OSHA, NTP, or IARC.
Other Health Risks: In large therapeutic doses, some risk of hypercalcemia exists for susceptible individuals.
Environmental Fate: Breaks down in water to calcium and acetate ions, both of which occur naturally.
Acute Eco-Toxicity: High concentrations may briefly alter water systems; otherwise, little risk at normal discharge levels.
Bioaccumulation: Not considered bioaccumulative.
Persistence: Degrades quickly in soil and water.
Preferred Disposal: Small amounts flushed with plenty of water if in line with local regulations.
Bulk Disposal: Take to landfill following local ordinances; avoid incineration to prevent acetic acid vapor.
Container Management: Clean thoroughly before recycling or disposal to prevent accidental contamination.
UN Number: Not typically regulated for transport.
Hazard Class: Not classified as dangerous.
Packing Group: Not applicable for standard amounts.
Transport Precautions: Use sealed, labeled containers to avoid leaks or spills in transit.
Labeling Requirements: Usually labeled according to local chemical safety law, noting calcium acetate and potential mild irritant.
Other Regulatory Listings: Used in food industry under E263 in many regions; recognized as safe in limited doses.
Workplace Controls: Standard workplace chemical safety guidelines apply, with greater restrictions for high-volume industrial use.
