Eye Contact: Rinse immediately with clean, gently flowing water for at least 15 minutes. Seek medical attention if discomfort continues.
Skin Contact: Remove contaminated clothing. Wash affected area with soap and water. Consult a physician if symptoms appear.
Inhalation: Move to fresh air. Support breathing as needed with supplemental oxygen. Consult a healthcare provider if respiratory symptoms do not resolve.
Ingestion: Rinse mouth. Do not induce vomiting. Drink water. Seek medical advice if large quantities are swallowed or adverse symptoms occur.
Advice to Physician: Symptomatic treatment and supportive care, treat burns from splashes like those from strong acids for eye exposures.
Suitable Extinguishing Media: Dry chemical, alcohol-resistant foam, carbon dioxide, water spray
Unsuitable Extinguishing Media: High-pressure water jets can stir up dust clouds
Special Hazards: Decomposition in heat or fire releases carbon oxides and irritating fumes
Fire-Fighter Protection: Self-contained breathing apparatus and full protective gear suggested. Avoid breathing combustion products.
Further Information: Keep containers cool with water spray. Prevent contaminated water runoff from entering watercourses or drains.
Personal Precautions: Wear chemical splash goggles, gloves, dust mask or respirator if significant dust is present.
Environmental Precautions: Stop discharge to soil, drains, or watercourses. Contain spill with dikes or inert material.
Spill Clean-Up Methods: Sweep up and shovel into suitable dry, sealable containers for disposal or recovery. Avoid generating dust.
Decontamination: Wash spilled residue with water, use non-metallic tools if possible.
Disposal: Collected material and washings handled following local hazardous waste protocols.
Handling: Work in a well-ventilated area or exhaust hood. Minimize contact with skin, eyes, and clothing. Avoid ingesting food, drink, or smoking near the material.
Storage: Keep in tightly closed containers in a dry, cool, well-ventilated place. Avoid contact with incompatible materials such as strong bases and oxidizers.
Container Materials: Store in dedicated plastic or chemically-resistant metal bins labeled for tartaric acid. Use secondary containment for bulk storage.
Storage Temperature: Below 30°C recommended for long-term stability. Avoid excessive heat and direct sunlight.
Occupational Exposure Limits: No OSHA PEL or ACGIH TLV established for tartaric acid. Use good workplace hygiene practices to keep dust below 10 mg/m3 as a general respirable dust guideline.
Engineering Controls: Local exhaust, dust collection, or general ventilation systems. Use process enclosures for powder transfers.
Eye Protection: Chemical splash goggles or safety glasses
Skin Protection: Chemical-resistant gloves (nitrile, PVC, or rubber), lab coat or overalls
Respiratory Protection: Dust mask (P2 or N95) if airborne concentrations approach nuisance levels. Respirators in poorly ventilated spaces.
Hygiene Measures: Wash hands after handling. Do not eat, drink, or smoke while working with this material.
Appearance: White crystalline powder or clear, colorless crystals
Odor: Odorless or barely perceptible acid tang
pH (1% solution): 2.0 – 2.5 at 25°C
Melting Point: 170°C - 172°C (338-342°F) decomposes before boiling
Boiling Point: Not applicable (decomposes prior to boiling)
Solubility in Water: 139 g/L at 20°C
Solubility in Other Solvents: Moderately soluble in ethanol, insoluble in ether and chloroform
Vapor Pressure: Negligible at ambient temperatures
Density: 1.76 g/cm3 at 25°C
Partition Coefficient (log Kow): -2.65 (predicted, low bioaccumulation risk)
Other Characteristics: Stable under normal ambient storage, deliquescent in humid air
Chemical Stability: Chemically stable under recommended storage and handling conditions. Breakdown can occur if heated above 170°C.
Conditions to Avoid: Excessive moisture, open flames or temperatures above melting point, strong light sources; high humidity accelerates clumping.
Incompatible Materials: Strong oxidizers, alkalis, bicarbonates, some metals (aluminum, zinc react slowly)
Hazardous Decomposition Products: Carbon dioxide, carbon monoxide, organic acids, acrid smoke or fumes in incomplete combustion
Polymerization: Does not undergo hazardous polymerization in storage or handling.
Acute Toxicity (Oral): Estimated LD50 rat > 2000 mg/kg
Skin Irritation: Mild and reversible irritation may occur; redness, itching reported in sensitive persons
Eye Effects: Causes moderate to severe irritation; risk of temporary damage with prolonged or unwashed exposures
Respiratory Effects: Dust can provoke throat irritation, cough, or sneezing; asthmatic individuals more sensitive
Sensitization: No known severe allergies; rare mild rashes documented
Long-Term Exposure: No evidence of carcinogenicity, mutagenicity, or reproductive toxicity from standard laboratory studies
Other Effects: Overdose by ingestion can cause gastrointestinal upset—vomiting, cramps, diarrhea
Aquatic Toxicity: Low toxicity to aquatic life at expected concentrations; rapid biodegradation in water and soil
Persistence and Degradability: Readily biodegradable according to OECD methods; primary breakdown to carbon dioxide and water
Bioaccumulation Potential: Low, as shown by partition coefficient and short environmental residence time
Mobility in Soil: High in moist soils; readily leaches but does not persist
Other Environmental Effects: Large accidental discharges increase acidity in water courses, which can harm aquatic organisms
