Name: Polaprezinc
Chemical Formula: C12H10N4O3Zn
Appearance: White to off-white powder or crystalline substance
Common Uses: Featured in clinical treatments for gastric and duodenal ulcers, known for mucosal protective functions, often used in nutritional supplementation and research settings
Odor: Odorless or slightly characteristic smell, not particularly offensive to most people
Main Hazards: Exposure may irritate eyes, skin, and respiratory tract. Inhalation of fine powder can lead to coughing or sneezing. Direct ingestion in larger quantities has the potential to upset the digestive system.
Warning Symbols: Generally not considered highly hazardous, but standard precautions suit occupational settings.
Routes of Entry: Mainly inhalation, dermal contact, accidental ingestion
Acute Effects: Mild irritation possible for sensitive individuals
Chronic Effects: Studies have not found major long-term toxicity at therapeutic doses, though repeated overexposure is not recommended
Main Ingredient: Polaprezinc complex (zinc ion chelated with L-carnosine)
Active Component Percentage: Typically between 16-23% zinc by weight, balance comprised of L-carnosine
Other Substances: Trace excipients may be present depending on manufacturing process
Chemical Family: Metal-amino acid complex
Inhalation: Move the person to fresh air. Seek attention if coughing or respiratory discomfort persists.
Skin Contact: Wash affected area with soap and water. Remove contaminated clothing if necessary.
Eye Contact: Rinse eyes gently with water for at least 15 minutes. Avoid rubbing.
Ingestion: Rinse mouth with water if the substance is swallowed accidentally. Medical advice should be sought if symptoms develop.
Symptoms of Exposure: No severe symptoms typically present with occupational exposures, but prompt basic first aid remains important.
Suitable Extinguishing Media: Water spray, foam, dry chemical, or carbon dioxide work for fires involving solid organic substances
Hazardous Combustion Products: Combustion might generate zinc oxides, nitrogen oxides, carbon monoxide, carbon dioxide
Protective Equipment: Firefighters should wear standard protective gear and a self-contained breathing apparatus
Additional Advice: Avoid inhalation of smoke or dust. Combustion residues may irritate airways.
Personal Precautions: Avoid creating dust. Use gloves and a particulate mask if required.
Environmental Precautions: Avoid spreading material into soil or water systems. Sweep up spillage with care.
Methods for Cleanup: Collect mechanically or with a damp cloth to reduce dust; dispose of in line with regulations.
Hygiene Recommendations: Wash hands thoroughly after cleanup; avoid eating or drinking during handling.
Handling: Limit dust generation; avoid inhalation and prolonged skin contact. Use personal protective equipment if necessary.
Storage: Store in a tightly closed container. Place in a cool, dry place away from direct sunlight, moisture, and incompatible chemicals.
Incompatibilities: Strong acids, bases, or oxidizing agents may react with polaprezinc.
Special Notes: Ensure the area is ventilated, and keep materials clearly labeled.
Engineering Controls: Use of local exhaust ventilation can help manage dust exposure in workspaces.
Eye Protection: Safety glasses or chemical splash goggles can prevent accidental exposure.
Skin Protection: Gloves, lab coats, or aprons provide a practical barrier.
Respiratory Protection: A particulate respirator comes in handy during dusty operations.
Work Practices: Wash hands before eating, drinking, or using restroom facilities.
State: Solid
Color: White to off-white
Odor: Nearly odorless
Boiling Point: Not applicable for solid substance
Melting Point: Specific melting point not widely reported, though stable at room temperature
Solubility: Poorly soluble in water, more soluble in dilute acids
pH: pH of a suspension lies close to neutral
Density: Varies by manufacturer
Chemical Stability: Stable under normal conditions of handling and storage
Incompatibility: Strong oxidizing agents, concentrated strong acids, and bases
Hazardous Decomposition: Zinc oxides, carbon oxides, nitrogen oxides from high-temperature decomposition
Other Risks: Avoid exposure to elevated temperatures and sources of ignition
Acute Toxicity: Oral toxicity studies suggest polaprezinc has a favorable safety profile at clinical doses
Potential Health Effects: Mild gastrointestinal disturbance at very high doses; symptoms like nausea, abdominal discomfort possible with large accidental ingestion
Chronic Exposure: Evidence does not point to significant risk when used within recommended ranges. Animal studies have not shown carcinogen or mutagen signals for this compound.
Special Sensitivities: Zinc sensitivity sometimes triggers mild reactions but rare in practice
Ecotoxicity: Zinc in high concentrations affects aquatic life, so safe handling matters near water sources.
Persistence and Degradability: Polaprezinc breaks down into zinc salts and amino acid derivatives, both of which occur naturally in the environment.
Bioaccumulation Potential: No strong evidence of bioaccumulation for this substance, though zinc itself can persist in some systems.
Mobility: Solid form limits rapid movement through soil.
Proper Disposal: Any waste should be offered to a certified waste disposal facility in accordance with local, regional, and national laws.
Avoid: Do not discharge into drains, surface water, or natural environments.
Packaging: Dispose of contaminated packaging following official regulations for non-hazardous but trace metal–containing waste.
Regulatory Status: Not classified as a dangerous good for transport across most agencies including UN, IMO, and IATA.
Precautions: Ensure containers are closed tightly and protected from damage or breakage.
Special Arrangements: Label shipments clearly if in large quantities; keep away from reactive chemicals during transport.
International Inventories: Zinc compounds are listed under various chemical regulations, and polaprezinc itself falls under dietary supplement controls in some jurisdictions.
Specific Restrictions: Medical and food safety regulations can impact its acceptance for various uses.
Workplace Guidelines: Where used in industry or laboratories, general occupational safety standards for metal-organic compounds apply.
