Impurities: Possible presence of minor organic or inorganic contaminants, residual solvents, trace mineral acids as per production batch, check batch specification for details
Inhalation: Move to fresh air, loosen tight clothing, allow rest, seek medical attention if breathing becomes difficult, provide oxygen if trained personnel are available
Skin Contact: Rinse area thoroughly with soap and water, remove contaminated clothing, avoid rubbing affected area, seek medical evaluation for persistent redness
Eye Contact: Rinse with gentle stream of lukewarm water for 15–20 minutes, keep eyelids apart, consult medical personnel for continued irritation
Ingestion: Rinse mouth with clean water, do not induce vomiting unless directed by medical provider, consult doctor immediately
Suitable Extinguishing Media: Water spray, dry chemical, foam, or carbon dioxide extinguishers used for organic solids
Unsuitable Extinguishing Media: High-pressure water streams (with risk of chemical runoff)
Specific Hazards: Emits fumes of sulfur oxides and organic vapors at high temperature, risk of toxic decomposition products if combustion occurs in confined space
Protective Equipment: Firefighters should wear self-contained breathing apparatus, chemical resistant suit and gloves to avoid exposure to off-gassing byproducts
Special Precautions: Minimize runoff into sewer systems, douse contaminated clothing with water before removal
Personal Precautions: Put on gloves, goggles, lab coat, and a dust mask to prevent contact or inhalation, restrict access to spill area
Containment: Stop leak if safe, prevent spilled solid from entering drains or waterways, cover area with damp absorbent material
Cleaning Methods: Scoop spilled product into a container for disposal, wash surfaces with plenty of water, ventilate area thoroughly after cleanup
Environmental Precautions: Avoid direct discharge to the environment, follow local disposal guidelines, report significant spills to authorities according to regulations
Handling: Wear protective clothing, work in a well-ventilated space, prevent dust formation by handling gently, avoid ingestion or inhalation, do not eat or drink in handling areas
Storage: Keep in tightly closed, labeled container, store in cool, dry place protected from sunlight and moisture, segregate from incompatible substances like strong oxidizers, acids, keep away from food and beverages
Special Requirements: Ground containers before transfer, use chemical-resistant shelving, keep records of usage and storage times to ensure traceability
Engineering Controls: Operate with local exhaust ventilation or fume hood to reduce airborne dust, use explosion-proof equipment if dust generation possible
Respiratory Protection: Use particulate filter mask (N95 or higher), especially during transfer
Hand Protection: Wear chemical-resistant gloves (nitrile or neoprene recommended)
Eye Protection: Tight-fitting safety goggles or face shield during preparation or spill cleanup
Skin Protection: Wear lab coat or overalls, avoid contact with exposed skin
Hygiene Measures: Wash hands and face after handling, wash contaminated clothing before reuse
Appearance: White to off-white crystalline powder
Odor: Faint characteristic odor or none
pH: 6.5–8.0 for 1% aqueous solution
Melting Point: Decomposes above 200°C
Boiling Point: Not applicable (decomposes before boiling)
Solubility: Soluble in water
Density: 1.35–1.44 g/cm³
Vapor Pressure: Negligible at room temperature
Flash Point: Not available (organic salt, non-volatile at room temperature)
Partition Coefficient (log Pow): Data not established
Chemical Stability: Stable under recommended storage conditions outside direct sunlight and moisture
Incompatible Materials: Strong oxidizers, acids, bases, peroxides, reducing agents
Hazardous Decomposition Products: Benzoyl byproducts, sulfur oxides, carbon oxides under decomposition or combustion
Reactivity: No risk of hazardous polymerization under standard conditions
Conditions to Avoid: Excess heat, moisture, direct light, incompatible substances
Acute Toxicity: Harmful orally; laboratory rats showed LD50 around 600 mg/kg, skin absorption data more limited but suggests mild to moderate irritation
Skin Irritation: Can cause inflamed or reddened skin in direct contact
Eye Damage: Rabbit test data showed moderate irritation; delayed recovery in some cases
Inhalation Effects: Prolonged exposure to high dust can cause mild respiratory irritation, sneezing, coughing
Chronic Effects: No known mutagenic or carcinogenic risks based on current studies, but chronic exposure data remain limited
Sensitization: Not known to be a skin sensitizer after repeated contact
Ecotoxicity: Acute aquatic toxicology: LC50 (fish, 96h) = 75 mg/L, EC50 (daphnia, 48h) = 50 mg/L; toxic in high concentrations to aquatic organisms
Persistence and Degradability: Chemical expected to degrade slowly in water and soil; sulfonate group lends moderate persistence
Bioaccumulation Potential: Low risk due to hydrophilic profile, unlikely to bioaccumulate appreciably in aquatic or terrestrial environments
Mobility: Readily soluble in water, mobile in soil if released
Other Adverse Effects: Limited data; recommend measures to avoid uncontrolled environmental release
Waste Disposal Methods: Collect product and contaminated cleaning materials in sealable, clearly marked chemical waste containers. Dispose through licensed hazardous waste contractor complying with local, regional and national regulations
Disposal of Packaging: Rinse empty containers thrice, puncture and send to hazardous waste facility, avoid general landfill
