Impurities: Minimal, mostly unreacted tartaric acid or benzoic acid derivatives in trace amounts
Inhalation: If inhaled, move affected person to fresh air and monitor for respiratory issues; seek medical attention if symptoms persist
Skin Contact: Wash affected area with plenty of water and mild soap, remove contaminated clothing; seek advice if irritation or redness continues
Eye Contact: Rinse eyes gently with running water for at least 15 minutes, keeping eyelids open; seek medical help if discomfort remains
Ingestion: Rinse mouth with water, do not induce vomiting, consult a doctor with the product label or packaging if large amounts swallowed
Note to Physician: Treat symptomatically and provide supportive care as needed
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, or water spray - use methods appropriate for surrounding fire
Unsuitable Extinguishing Media: Do not use a solid water stream, which may spread the burning material
Hazards from Combustion: Carbon oxides and unidentified toxic fumes can form in incomplete combustion
Fire Fighting Instructions: Wear self-contained breathing apparatus and protective equipment; avoid breathing fumes and run-off water
Special Protective Equipment: Standard firefighting gear, chemical-resistant gloves, eye/face protection, and breathing apparatus
Personal Precautions: Avoid contact with skin, eyes, and clothing; ensure proper local exhaust ventilation; use personal protective equipment
Environmental Precautions: Prevent entry into drains, waterways, or soil; keep spilled material from contaminating surface water
Methods for Clean-Up: Sweep up carefully without creating dust, place into suitable labeled container for disposal, ventilate area
Cleanup Equipment: Use chemical-resistant gloves, dust mask or respirator, eye protection; wash hands and affected areas after cleanup
Safe Handling: Handle in a well-ventilated area, use appropriate personal protection, avoid dust inhalation and ingestion; wash hands before breaks and after use
Storage Conditions: Store in a cool, dry, well-ventilated place away from incompatible materials such as strong bases and oxidizers
Incompatible Materials: Oxidizing agents, strong bases, strong acids, moisture
Specific Storage Requirements: Keep tightly closed in original container, away from sunlight and sources of ignition; label workspace for easy emergency access
Safe Transfer Procedures: Minimize movement in open air; use closed transfer systems if available
Engineering Controls: Use laboratory fume hood or local exhaust; ensure adequate general ventilation
Personal Protective Equipment: Chemical-resistant gloves (nitrile or PVC), safety goggles, lab coat, and, if dust-producing, NIOSH-approved dust respirator
Hygiene Measures: Wash hands, forearms, and face thoroughly after handling, especially before eating or drinking; remove contaminated clothing
Exposure Limit Values: No established occupational exposure limits; keep airborne levels as low as possible
Environmental Controls: Prevent spills from entering natural water systems or soil; filter exhaust if possible
Appearance: White to off-white crystalline powder
Odor: Odorless or faint aromatic smell
pH (solution): Not applicable (insoluble in water)
Melting Point/Range: 192-194°C

Hazardous Reactions: No hazardous polymerization expected; violent reactions with oxidizers possible
Conditions to Avoid: Extreme heat, exposure to light, moisture, contact with incompatible chemicals
Incompatible Materials: Strong oxidizing agents, strong bases, nitric acid, strong acids
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, possible organic fumes on thermal decomposition
Acute Toxicity: Low toxicity; no available LD50 or LC50 values, but not known to be acutely toxic
Skin Corrosion/Irritation: May cause mild irritation upon prolonged contact
Serious Eye Damage/Irritation: Dust or splashes may irritate eyes
Respiratory Sensitization: Not a known respiratory sensitizer; dust inhalation can cause mild irritation in sensitive individuals
