Eye Contact: Rinse carefully with water for at least 15 minutes, keep eyelids open, seek medical attention if irritation persists
Skin Contact: Wash with plenty of water and soap, remove contaminated clothing, seek medical attention for persistent irritation
Inhalation: Move to fresh air, provide oxygen if breathing is difficult, seek medical attention if respiratory discomfort continues
Ingestion: Rinse mouth with water, drink water, do not induce vomiting, seek medical advice if large amounts are swallowed or symptoms develop
Acute Symptoms: Possible mild irritation, no severe risks expected under typical use
Notes for Physicians: Treat symptomatically, no antidote required
Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, foam
Unsuitable Media: Avoid using a heavy water stream on fires involving chemical stockpiles
Special Fire-Fighting Procedures: Use self-contained breathing apparatus, wear chemical-resistant protective gear
Explosion Data: Dust may form an explosive mixture with air, avoid generating dust clouds
Hazardous Combustion Products: Magnesium oxide, carbon oxides (CO, CO2)
Advice for Firefighters: Approach fire from upwind, cool adjacent containers with water
Personal Precautions: Wear appropriate protective equipment such as gloves, goggles, dust mask
Environmental Precautions: Prevent large spills from entering waterways or sewers
Methods for Containment: Avoid generating dust, contain spill with inert absorbent such as sand or vermiculite
Cleanup Procedures: Sweep up and place in a suitable container for disposal, ventilate area, wash residues away with plenty of water
Special Tools Required: Dustpan, brush, vacuum with HEPA filter if available
Disposal Considerations: Dispose of according to local, regional, and national regulations
Handling: Use in well-ventilated areas, avoid dust generation, wear protective gloves and eyewear during handling or transfer
Storage: Store in a cool, dry location in tightly closed containers; avoid humidity and direct sunlight
Incompatible Materials: Strong acids and oxidizing agents
Hygiene Measures: Clean hands thoroughly after handling, prevent eating, drinking, or smoking in handling areas
Spill Prevention: Keep containers closed when not in use, use appropriate tools for transfer
Exposure Limit Values: No official occupational exposure limits set for magnesium malate
Engineering Controls: Local exhaust ventilation recommended where dust forms
Personal Protective Equipment: Safety glasses or chemical goggles, impervious gloves, laboratory coat, NIOSH-approved dust respirator if dust levels exceed comfort
Environmental Exposure Controls: Do not release in large amounts to soil or water systems
General Safety Practices: Follow good laboratory hygiene, keep containers labeled, report accidental exposures immediately
Appearance: White to off-white powder

Conditions to Avoid: Excessive heat, open flame, moisture
Materials to Avoid: Strong acids, oxidizers
Hazardous Decomposition Products: Releases magnesium oxide and carbon oxides on decomposition
Polymerization: Does not occur
Shelf Life: Up to two years under recommended storage conditions
Acute Toxicity: Oral LD50 (rat) not established; magnesium salts generally considered low toxicity, very large doses may cause digestive upset
Skin Corrosion/Irritation: Not expected to cause significant irritation on intact skin
Serious Eye Damage/Irritation: May cause mild, reversible eye irritation
Respiratory Sensitization: Slight risk of irritation if dusty conditions prevail
Germ Cell Mutagenicity: No evidence from relevant data
Carcinogenicity: Not listed as carcinogen by IARC, NTP, OSHA
Reproductive Toxicity: No evidence of reproductive toxicity
STOT – Single/Repeated Exposure: No significant hazards identified for single or prolonged exposure based on current studies
Aspiration Hazard: Not an aspiration toxicant
Ecotoxicity: No known significant effects or critical hazards, low toxicity to aquatic life in typical concentrations, avoid large releases
Persistence and Degradability: Inorganic magnesium degrades in the environment into naturally occurring ions; malate biodegrades easily
Bioaccumulative Potential: Low potential for bioaccumulation
Mobility in Soil: Mobile in water, magnesium and malate are released as nutrients in soil
Other Adverse Effects: None known if handled responsibly
Environmental Fate: Dilutes and disperses in surface waters, does not persist or pose a chronic hazard
Disposal Methods: Dispose of in accordance with local, regional, or national regulations for non-hazardous chemicals
Container Disposal: Rinse thoroughly before discarding as general waste or recycle where possible
