Chemical Name: L(+) Tartaric Acid
Content: 99% or greater (food or industrial grade, as specified)
Impurities: Trace amounts of water (<1%), negligible levels of inorganic salts
Other Ingredients: No additional substances intentionally present; product is not blended with any anti-caking agents in this form
Eye Contact: Rinse immediately with clean water for at least 15 minutes, keeping eyelids apart; seek medical attention if irritation continues
Skin Contact: Wash exposed area with mild soap and water; remove contaminated clothing; if rash or irritation appears, obtain medical advice
Inhalation: Move to fresh air; rest in comfortable position; rinse mouth and nose with water; persistent symptoms require medical assessment
Ingestion: Rinse mouth; drink water if person is conscious; seek medical advice for discomfort or persistent symptoms
Suitable Extinguishing Media: Water spray, dry chemical, foam, or carbon dioxide; avoid strong jets that may spread dust
Unsuitable Extinguishing Media: None known for tartaric acid; verify based on packaging material
Hazardous Combustion Products: Carbon oxides (CO, CO2), smoke, minor organic decomposition products at very high temperature
Fire and Explosion Hazards: Fine powders may create dust clouds; potential risk of dust explosion in confined space with ignition source
Protective Equipment: Firefighters should wear self-contained breathing apparatus and protective clothing to limit exposure to fumes
Personal Precautions: Avoid breathing dust; use particulate respirator if necessary; ventilate area; prevent contact with eyes, skin
Environmental Precautions: Prevent bulk spills from entering drains, surface water, or soil; material is water soluble and increases organic load if discharged
Cleanup Methods: Sweep or shovel dried powder into suitable containers; avoid generating dust; flush remainder with water if permitted and area can be cleaned safely
Disposal: Gather residue for authorized waste disposal as per regulations
Handling: Control dust formation using proper transfer techniques; keep good ventilation in processing or packing areas; wash thoroughly after handling
Protective Measures: Use goggles and dust mask where airborne particles are present; minimize skin contact with glove use if necessary
Storage Conditions: Store in tightly sealed containers, away from moisture; keep in dry, cool, well-ventilated area, away from alkaline materials and strong oxidizers
Further Information: Keep product in manufacturer’s packaging or approved bulk bins; avoid prolonged exposure to air to prevent caking and absorption of humid air
Occupational Exposure Limits: Not specified for tartaric acid; general dust limits apply (in many countries, total dust <10 mg/m³, respirable dust <5 mg/m³)
Engineering Controls: Local exhaust or process enclosure to minimize airborne dust
Personal Protection: Use safety glasses with side shields, dust mask or respirator as appropriate for concentration, gloves for extended handling
Hygiene Practices: No eating, drinking, or smoking where material is handled; wash thoroughly after exposure
Appearance: Fine, white crystalline powder
Odor: Odorless or very faint acidic smell
pH: Approx. 2 (1% solution in water)
Melting Point: 170°C (decomposes above)
Solubility: Freely soluble in water, slightly soluble in ethanol
Density: 1.79 g/cm³
Molecular Weight: 150.09 g/mol
Other Data: Stable under standard conditions; absorbs moisture from air
Chemical Stability: Stable in dry, sealed containers under normal handling and storage temperatures
Incompatible Materials: Strong bases and strong oxidizers; reacts with carbonates to form CO₂ gas; incompatible with sodium or potassium hypochlorite solutions
Hazardous Reactions: Exposure to humidity increases caking; vigorous reaction possible with alkali and certain hypochlorites
Decomposition Products: Carbon oxides formed under fire or high temperature
Polymerization: Not likely under normal conditions
Acute Toxicity: Low—oral LD50 (rat) 4900 mg/kg; not considered toxic at food additive levels
Skin Corrosion/Irritation: Mild irritant to skin on extended contact; regular brief contact presents low risk
Eye Damage/Irritation: Direct dust may cause soreness and watering; avoid rubbing if exposed
Respiratory Effects: Inhalation of dust causes cough or throat irritation; large amounts may temporarily overwhelm mucosal defenses
Long-Term Effects: No evidence of carcinogenicity or chronic toxicity in approved uses
Sensitization: Not known to produce allergic responses in general population
Ecotoxicity: Readily biodegradable; breaks down rapidly in soil and water into naturally occurring products
Aquatic Toxicity: Low aquatic toxicity; high concentrations may alter pH in small bodies of water, temporarily affecting aquatic organisms
Bioaccumulation: Not likely to accumulate in living organisms
Mobility in Soil: Soluble in water, will leach into soil, but decomposes quickly by microbial action
Additional Information: Use with reasonable care in large quantities near water to limit unnecessary nutrient input
Waste Disposal Methods: Dispose as non-hazardous chemical waste if uncontaminated; dilute solutions may be disposed with copious amounts of water after ensuring compliance with local wastewater regulations
Packaging Disposal: Used containers should be emptied thoroughly and recycled or disposed in accordance with regulations; avoid releasing large quantities to environment
Legal Note: Check local, regional, and national legislation before disposal of bulk product
UN Number: Not regulated for road, rail, air, or sea transport
Transport Hazard Class(es): Not classified as hazardous under international transport rules
Packing Group: Not applicable
Environmental Hazards: None required based on typical shipment form
Additional Precautions: Ship in sealed, labeled containers; protect from moisture, segregate from incompatible substances during transport
Food Additive Status: Approved for use in many countries (e.g., FDA GRAS status in the United States, E334 in the EU)
Inventory Listing: Present on major chemical inventories, including TSCA, EINECS, AICS, DSL/NDSL
Occupational Health Regulations: General dust regulations may apply to workplace exposure; no specific mandatory limits for tartaric acid powder
Labeling: Standard labeling required for food and industrial use; symbols not required for non-hazardous classification in transport
Other Compliance: Meets safety standards for handling, labeling, and transport as determined by international and regional regulatory agencies
Providing high-quality chemical products and logistics solutions for global trade partners.
