Impurities: Commercial batches may contain minimal water, traces of tartaric acid or sodium salts
Additives: No additional stabilizers or preservatives added under standard supply
Eye Contact: Rinse gently with plenty of water for at least 15 minutes, seek medical attention if irritation persists
Skin Contact: Wash affected area with soap and water, remove contaminated clothing
Inhalation: Move injured person to fresh air, keep at rest, seek medical assistance if respiratory symptoms continue
Ingestion: Rinse mouth with water, drink water to dilute if conscious, do not induce vomiting, obtain medical help if feeling unwell
Special Notes: Allergic reactions rare, but report immediately if shortness of breath develops
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Unsuitable Media: Direct water jet may disperse dust clouds
Special Hazards: In combustion, releases CO, CO₂, low levels of organic acids; fine dust can ignite
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective clothing
Additional Information: Avoid inhaling fumes generated from burning; remove containers from fire zone if safe
Personal Precautions: Wear dust-proof gloves, goggles, and suitable respirator
Environmental Precautions: Prevent material from entering drains, watercourses, or soil
Methods for Cleanup: Gently sweep or scoop spilled product into secure containers, use industrial vacuum with HEPA filter for residue
Disposal of Waste: Place waste in labeled, sealed containers for authorized chemical disposal
Other Considerations: Avoid creating airborne dust during cleanup
Handling: Use in well-ventilated area, minimize dust generation, avoid ingestion and eye or skin contact
Storage: Store in sealed containers away from moisture and incompatible materials, keep in a dry, cool space
Incompatibilities: Store separate from strong oxidizers and acids; keep container tightly closed
Special Handling Equipment: Local exhaust ventilation and dust collection recommended in bulk operations
Storage Life: Stable for several years under recommended conditions, but exposure to moisture reduces efficacy
Exposure Limits: No OSHA or ACGIH limits set; keep airborne dust below nuisance dust threshold (10 mg/m³ recommended)
Engineering Controls: Use appropriate dust extraction systems and HEPA-filter vacuums
Personal Protection: Chemical-resistant gloves, safety goggles, dust mask with N95 or better rating
Hygiene Measures: Wash hands after handling, avoid contact with eyes, do not eat, drink, or smoke while using
Additional Protection: Wear lab coat or protective clothing to prevent contamination of street clothes

Acute Toxicity: Low oral and skin toxicity; estimated LD50 (rat, oral): >2000 mg/kg
Chronic Effects: No significant data on chronic toxicity in humans
Potential Health Effects: Eye or skin irritation, cough or sore throat from dust inhalation
Carcinogenicity: Not listed by IARC, NTP, or OSHA as carcinogenic
Reproductive Toxicity: No evidence found for teratogenic or reproductive effects
Sensitization: Not a known sensitizer
Ecotoxicity: Aquatic organisms show low risk at common exposure levels
Mobility: Soluble in water, can leach through soil into groundwater in significant spills
Degradability: Biodegradable; breaks down quickly in environment
Bioaccumulation: Unlikely due to low fat solubility and rapid breakdown
Other Adverse Effects: Material should not be released in bulk to water bodies or drainage systems
Waste Disposal Methods: Dispose of in accordance with local, regional, and national regulations; small amounts can enter normal waste streams, but bulk material should go to approved chemical disposal
Contaminated Packaging: Rinse and reuse if possible or dispose of as chemical waste
Special Precautions: Small-scale disposal through dilution in excess water, large-scale through licensed chemical waste contractors
