Ingestion: Rinse mouth with water; do not induce vomiting; seek medical guidance for persistent symptoms
Flash Point: Not flammable under normal processing and storage conditions
Extinguishing Media: Use water spray, carbon dioxide, dry chemical or foam; select agents suitable for surrounding materials
Special Hazards: Produces irritating fumes such as carbon oxides when burned at elevated temperatures
Protective Equipment: Firefighters wear self-contained breathing apparatus, gloves, and full protective gear
Explosion Risk: Fine dust dispersed in air has minimal risk of dust explosion under ordinary handling
Personal Precautions: Use personal protective equipment to avoid inhalation and contact
Environmental Precautions: Prevent spillage from entering drains or watercourses
Methods for Cleanup: Collect material mechanically; use a vacuum equipped with a HEPA filter if available; avoid sweeping to minimize dusting; place in labeled, sealable containers for disposal or recovery
Decontamination: Ventilate spill area, wash residues with plenty of water
Safe Handling: Wear suitable gloves, masks, and protective eyewear; use in designated areas with proper ventilation; avoid eating, drinking, or smoking in work space
Storage Conditions: Store in tightly sealed containers made of compatible materials; keep container dry, away from sources of moisture and strong oxidizers; preferred temperature range is ambient, up to 25°C
Incompatibility: Avoid mixing with strong acids, strong bases, oxidizing agents; keep segregated from foods not labeled for supplements
Exposure Limits: No official occupational exposure limit for magnesium gluconate; general dust threshold: 10 mg/m³ (inhalable, total particulates, time-weighted average)
Engineering Controls: Use local exhaust ventilation or process enclosures for dust containment; provide eyewash stations in immediate working area
Personal Protection: Wear dust mask (P2 or N95), safety goggles, latex/nitrile gloves, laboratory coat or coveralls
Hygiene Measures: Wash hands before eating, after handling; launder contaminated clothing before reuse
Appearance: White to off-white, free-flowing, crystalline powder
Odor: Odorless or slight carbohydrate odor
pH (1% solution): 6.5 – 7.5
Melting Point: Decomposes prior to melting, above 170°C
Solubility: Water-soluble, insoluble in non-polar organic solvents
Boiling Point: Not applicable
Density: 1.7 g/cm³
Vapor Pressure: Negligible
Partition Coefficient: Not determined; expected to be low due to high water solubility
Other: Stable under recommended storage; hygroscopic if left open
Chemical Stability: Stable under normal handling, storage, and temperature range
Reactivity: No hazardous reactions anticipated with common food ingredients; may react with oxidizers or acids at elevated temperatures
Conditions to Avoid: Moisture, excessive heat
Hazardous Decomposition: Produces carbon dioxide, carbon monoxide, magnesium oxides when heated to decomposition
Polymerization: Not known to occur
Acute Toxicity: Oral LD50 (rat): greater than 5000 mg/kg, indicating very low toxicity
Irritation: Dust may cause mild and transient mechanical irritation to eyes, skin, and respiratory tract
Chronic Effects: No evidence of carcinogenicity, reproductive toxicity, or mutagenicity found in available literature
Allergy Potential: Not recognized as an allergen or sensitizer
Additional Information: Safe for use in food and supplements at established levels, as recognized by regulatory authorities
Ecotoxicity: Low immediate risk for aquatic or terrestrial environments; ingredient naturally degrades
Persistence and Degradability: Decomposes to naturally occurring ions and glucose in environment
Bioaccumulation: Unlikely due to water solubility and metabolic breakdown
Mobility in Soil: Highly mobile and disperses readily in water
Other: Not expected to cause adverse effects in natural concentrations used in supplements or food
Product Waste: Dispose according to local, regional, and national legislation; landfilling or incineration in line with non-hazardous organic chemicals
Contaminated Packaging: Clean before recycling whenever possible; if heavily contaminated, treat the same as chemical waste
Recommended Methods: Prevent release to the environment; do not incinerate material with food residues
