Chemical formula: C6H10O4Zn
CAS number: 557-28-8
Impurities: May contain trace moisture or propionic acid as byproducts from production
Other hazardous components: None expected above threshold limits relevant to workplace safety
Eye contact: Rinse cautiously with water for 15 minutes, remove contact lenses if present and easy to do, seek medical attention if irritation persists
Skin contact: Remove contaminated clothing, wash with plenty of soap and water, obtain medical advice for persistent redness or irritation
Inhalation: Move person to fresh air, provide oxygen if breathing is difficult, seek medical help if coughing or irritation lingers
Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical attention and provide product information
Note for physicians: Treat symptomatically, monitor for respiratory distress and secondary symptoms such as nausea or vomiting
Suitable extinguishing media: Dry chemical, foam, carbon dioxide, water spray for larger fires
Unsuitable media: Direct water stream risks spreading powder, avoid contact with reactive metals
Special hazards: Dust can form explosive mixtures with air in rare cases, decomposes at high temperatures releasing irritating fumes such as zinc oxides and propionic acid vapors
Protective equipment for firefighters: Self-contained breathing apparatus, full protective gear to limit exposure to smoke and fumes
Special firefighting procedures: Fight fire from upwind side, control run-off to prevent entry into drains or watercourses, cool containers exposed to flames
Personal precautions: Use personal protective equipment including gloves, safety goggles, and dust mask, evacuate unprotected personnel from area
Environmental precautions: Prevent further leakage or spillage if safe to do so, keep from entering waterways, soil, or drains
Methods for clean-up: Collect spillage using a vacuum equipped with HEPA filtration or damp sweeping to limit dust, transfer to labeled containers for disposal, ventilate area once clean-up finishes
Disposal: Place collected material in designated hazardous waste containers, seal and label appropriately until disposal
Safe handling: Minimize dust generation, work in well-ventilated area, avoid direct contact with skin or eyes, do not eat or drink near product
Storage conditions: Store in tightly closed, original containers in a dry, cool, and well-ventilated location away from sources of moisture and incompatible substances such as strong oxidizers and acids
Special storage requirements: Protect from humidity and physical damage, store away from foods and feedstuffs, ensure containers remain sealed when not in use
Engineering controls: Use local exhaust or general ventilation to control airborne dust, provide emergency eyewash stations near where material is handled
Personal protective equipment: Safety goggles or face shield for eye protection, chemical-resistant gloves such as neoprene or nitrile, lab coat or apron for skin protection, NIOSH-approved dust mask or respirator if airborne exposure is possible
Exposure limits: Occupational exposure limits for zinc compounds generally sit at 2 mg/m³ (respirable, as Zn), check local regulations for specifics
Hygiene measures: Wash hands thoroughly after handling, remove contaminated clothing before entering eating areas
Appearance: White or off-white crystalline powder
Odor: Mild, slightly pungent (from propionic acid)
Molecular weight: 211.54 g/mol
Melting point: Starts to decompose near 205°C
Solubility: Slightly soluble in water, more readily dissolves in organic solvents such as methanol or ethanol
Boiling point: Not applicable—product decomposes before boiling
pH: Solution tends to be slightly acidic
Vapor pressure: Negligible at standard temperature
Flammability: Not classified as highly flammable, but dust may ignite in confined areas
Bulk density: Ranges from 0.8 to 1.2 g/cm³ (typical for crystalline solids)
Other properties: Stable under most storage and handling conditions, generates little static electricity unless handled in bulk
Chemical stability: Stable under recommended storage and handling conditions
Thermal decomposition: Releases irritating fumes of zinc oxides and propionic acid
Reactivity: Reacts with strong acids forming propionic acid and zinc salts, avoid mixing with oxidizers
Hazardous reactions: Does not polymerize, no dangerous reactions expected except under extreme exposures
Conditions to avoid: Moisture, high heat, open flames, strong oxidizing agents, and acids
Routes of exposure: Inhalation, ingestion, skin and eye contact
Acute toxicity: Estimated oral LD50 for rats sits above 2000 mg/kg indicating relatively low toxicity but still harmful in quantity
Skin irritation: Prolonged or repeated contact may cause redness, dryness, or irritation
Eye irritation: Causes burning, watering, and redness on direct contact
Chronic effects: Long-term exposure may aggravate pre-existing skin, eye, or respiratory conditions
Carcinogenicity: No data linking to cancer in humans
Mutagenicity / Reproductive toxicity: No specific data, not regarded as a genotoxic or reproductive risk under normal handling
Sensitization: Low risk for sensitization, though sensitive individuals may react to zinc ions
Ecotoxicity: Toxic to aquatic life in excessive concentrations; zinc compounds often persist and accumulate in aquatic environments
Mobility: Limited mobility in soil due to zinc’s strong affinity for organic and inorganic material
Persistence and degradability: Not readily degradable, zinc ions are stable and accumulate over time
Bioaccumulation: Zinc builds up in aquatic organisms, impacts higher up the food chain
Aquatic toxicity values: LC50 (fish, 96 hr): typically ranges from 0.1-1 mg/L for soluble zinc compounds
Other adverse effects: Runoff from improper disposal harms streams, rivers, and ponds
Waste treatment methods: Collect residues and contaminated materials in sealed, labeled containers
Disposal of product: Dispose of through a licensed chemical waste disposal contractor following local and national regulations
Disposal of packaging: Decontaminate containers if possible, then recycle or dispose of as hazardous waste based on local rules
Precautions for disposal: Prevent waste from entering surface water, soil, and drains, never discharge to environment
UN number: Not classified as hazardous for transport under most regulations
Proper shipping name: Zinc Propionate
Transport hazard class: Generally does not fall under dangerous goods regulations, check with carrier for regional variations
Packing group: Not assigned
Environmental hazards: Not classified as marine pollutant, though excessive spills require reporting
Special transport precautions: Prevent package damage, ensure containers remain tightly sealed and dry during shipment
Transport labels: None required beyond standard product and handling identification
Regulatory status: Zinc Propionate appears on chemical inventories such as TSCA (US), REACH (EU), DSL (Canada)
OSHA classification: Hazardous substance under US worker safety standards
SARA Title III: Zinc compounds included as reporting chemicals under Section 313
Other regulations: Subject to workplace exposure limits for zinc, governed by national and regional laboratory safety laws
Labeling requirements: Requires hazard pictograms, warning statements, and supplier information on all containers
