Product Name: Manganese(II) gluconate
Synonyms: Gluconic acid, manganese(2+) salt
Chemical Formula: C12H22MnO14
CAS Number: 6485-39-8
Manufacturer: Provided upon request
Recommended Uses: Nutritional supplement, laboratory reagent, fortification in food products
Emergency Contact: Supplied by distributor or manufacturer
Classification: Not classified as hazardous according to GHS
Routes of Exposure: Inhalation, ingestion, dermal, ocular
Potential Health Effects: Over-exposure through inhalation may cause irritation of the respiratory tract, headache, dizziness, or cough. Skin or eye contact can bring irritation, redness, or itching. Ingestion of small quantities rarely leads to acute symptoms, though chronic exposure has links to central nervous system impacts.
Pictogram: None required for typical exposure
Signal Word: None
Hazard Statements: May cause irritation to eyes, skin, or respiratory tract on excessive exposure.
Precautionary Statements: Avoid occupational exposure if unprotected, observe workplace limits.
Chemical: Manganese(II) gluconate
CAS Number: 6485-39-8
Proportion: >98% (by weight)
Impurities: Less than 2%; often traces of gluconic acid or manganese salts
Eye Contact: Rinse with clean water for at least 10 minutes. Avoid rubbing the eyes. Medical attention is needed if redness or irritation continues.
Skin Contact: Wash with water and a mild soap. Remove contaminated clothing. Persistent irritation deserves medical evaluation.
Inhalation: Move victim to fresh air. If breathing difficulties remain, seek medical advice.
Ingestion: Rinse mouth. Drink water to dilute. Only seek urgent help if substantial amounts consumed or symptoms persist.
Special Notes: Medical personnel should address symptomatically.
Suitable Extinguishing Agents: Water spray, foam, dry chemical, or carbon dioxide
Fire Hazards: Product itself does not burn and does not pose a flammability risk. Combustion can produce oxides of manganese and carbon.
Protective Equipment: Firefighters should use full protective gear, including self-contained breathing apparatus.
Explosion Risk: No significant risk known.
Personal Protection: Use dust mask or respirator, wear gloves and goggles to prevent direct contact.
Spill Response: Scoop up to container for disposal. For small spills, avoid generating dust and use damp methods. Ensure adequate ventilation.
Environmental Caution: Large spills entering water systems may disturb aquatic life. Limit entry to drainage systems or surface waters.
Handling Practices: Avoid breathing dust. Wear basic PPE in occupational settings. Use with local exhaust ventilation.
Storage Conditions: Store tightly closed in a cool, dry, and well-ventilated area. Keep away from incompatible materials such as strong oxidizers and acids.
Incompatibilities: Avoid storing with concentrated acids or powerful oxidizing agents.
Special Precautions: Keep container labeled and avoid rough handling to prevent breakage.
Occupational Exposure Limits: ACGIH TLV for manganese (as Mn): 0.1 mg/m³ (inhalable fraction)
Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to reduce airborne levels.
Personal Protective Equipment: Respiratory protection in dusty areas, safety goggles, gloves, and lab coat recommended.
Hygiene Measures: Wash hands before eating, smoking, or leaving the work area.
Appearance: Pale pink to light brown powder or crystals
Odor: Odorless
Solubility: Freely soluble in water, insoluble in alcohol
Melting Point: Decomposes before melting point is reached
pH (1% solution): Slightly acidic to neutral
Boiling Point: Not applicable (decomposes)
Density: Approximately 1.8 g/cm³
Vapor Pressure: Not applicable
Chemical Stability: Stable under recommended storage conditions
Conditions to Avoid: Excess moisture, extreme heat
Incompatible Materials: Strong acids, oxidizing agents
Hazardous Decomposition Products: Oxides of manganese, carbon monoxide, carbon dioxide on combustion or excessive heating
Polymerization: Will not occur
Acute Toxicity: Low toxicity for single oral or dermal exposures
Chronic Toxicity: Long-term inhalation or ingestion may contribute to adverse effects on the central nervous system, especially for workers in manufacturing environments. Manganese overexposure links to neurological symptoms similar to Parkinson’s disease.
Skin and Eye Irritation: Can irritate on significant contact
Sensitization: Not known to cause allergic sensitization
Mutagenicity/Carcinogenicity: No evidence of genotoxic properties or carcinogenicity from current studies.
Aquatic Toxicity: Manganese compounds can accumulate in aquatic environments. High concentrations in surface water harm fish and other aquatic organisms, especially with repeated or large releases.
Persistence and Degradability: Not rapidly degradable but disperses in water and soil. Manganese is a naturally occurring element.
Bioaccumulative Potential: Negligible for gluconate complexes.
Mobility in Soil: Fairly mobile, especially in soluble form.
Other Adverse Effects: Avoid disposal to natural water systems unless treated.
Waste Disposal Methods: Collect waste in designated containers. Disposal at licensed chemical waste facilities, according to local regulations.
Container Disposal: Triple rinse and dispose of as hazardous or non-hazardous waste based on local requirements.
Environmental Precautions: Prevent large releases into sewers, storm drains, or waterways.
Recycling: Not typically recycled or reused; prioritize reduction of excess chemical inventory.
UN Number: Not regulated for transport
ADR/RID/IMDG/IATA: Not classified as dangerous goods
Transport Precautions: Avoid damage to packaging; secure containers to prevent spillage in transit. Follow shipping regulations for chemical substances.
Special Measures: Label transport containers clearly if shipped in bulk.
EU Regulations: Not classified as hazardous under CLP Regulation (EC No 1272/2008).
US Regulations: Not listed as a hazardous waste under RCRA. Listed under TSCA inventory for industrial chemicals. OSHA does not consider manganese(II) gluconate by itself as a hazardous chemical, though manganese compounds fall under specific workplace exposure guidelines.
Other Regulations: Complies with international standards such as REACH. Review local regulations for use in food or supplements.
Label Requirements: Product labeling should indicate chemical identity and necessary precautions for occupational settings.
Employee Training: Facilities using or handling require routine chemical safety training to reduce risks.
