Pictograms: Corrosive, Exclamation mark, Environment
Precautionary Statements: Avoid contact with skin, eyes, and clothing, Avoid release into the environment, Wear protective gloves, clothing, eye and face protection, Do not breathe dust or mists
Chemical Name: Benzethonium Chloride
Concentration: 98-100% (varies depending on supplier and intended use)
Impurities: May contain trace amounts of related quaternary ammonium compounds, limited to regulated specifications
Additives: No intentional additives listed, some preparations dissolve in water or alcohol
Inhalation: Move person to fresh air immediately, provide artificial respiration if breathing slows or stops, seek prompt medical care
Skin Contact: Remove contaminated clothing, flush skin with copious amounts of water and mild soap, seek medical attention if irritation persists or burns appear
Eye Contact: Rinse cautiously with clean water for a minimum of 15 minutes, keep eyelids open, remove contact lenses, get medical attention right away
Ingestion: Rinse mouth thoroughly, do not induce vomiting, never give anything by mouth to an unconscious person, contact poison control or a physician urgently
Suitable Extinguishing Media: Water spray, carbon dioxide, foam, or dry chemical fire extinguishers
Specific Hazards: May emit toxic fumes such as hydrogen chloride and nitrogen oxides
Protective Equipment: Firefighters require self-contained breathing apparatus and full protective clothing
Special Precautions: Evacuate area, stay upwind during fire, remove containers if safe to do so, use water spray to cool fire-exposed containers
Personal Precautions: Evacuate area, wear chemical-resistant gloves, goggles, boots, and protective clothing
Environmental Precautions: Prevent release to drains, sewers, and waterways, contain spillage using non-combustible absorbent materials such as sand or vermiculite
Clean-up Methods: Scoop up and transfer spilled product to clearly labeled disposal containers, wash area with water and detergent, ventilate area thoroughly
Handling: Handle with local exhaust or general dilution ventilation, avoid generating dust or aerosols, minimize splashing, wash hands after handling, keep container tightly closed
Storage: Store locked up, keep in original tightly closed container, store in cool, dry, well-ventilated area away from foodstuffs and incompatible substances such as strong oxidizers and acids, shield from direct sunlight and moisture, segregate from flammables and combustibles
Occupational Exposure Limits: No specific occupational limits established, follow internal guidelines and regulations for chemical handling
Engineering Controls: Ensure good general ventilation, consider local exhaust at points of emission
Personal Protection: Eye/face protection (chemical safety goggles or face shield), hand protection (chemical-resistant gloves such as nitrile or neoprene), protective clothing (long-sleeved, chemical-resistant apron or gown), respiratory protection (if ventilation insufficient, use NIOSH-approved respirators for dust or mists)
Appearance: White or off-white crystalline powder, sometimes granular
Odor: Odorless or faint aromatic odor
Solubility: Soluble in water and alcohol,
pH (1% solution): Typically between 5 and 7
Melting Point: 163–168°C
Boiling Point: Decomposes before boiling
Vapor Pressure: Negligible at room temperature
Specific Gravity: 1.0–1.1 (water = 1)
Flash Point: Not applicable to solids
Partition Coefficient (n-octanol/water): Not measured directly, but moderate due to amphiphilic structure
Decomposition Temperature: Above 200°C (releases toxic fumes)
Chemical Stability: Stable under normal storage and handling conditions, sensitive to light and moisture
Reactivity: May react with strong oxidizing agents or acids
Hazardous Decomposition Products: Emits toxic fumes of hydrogen chloride, nitrogen oxides if heated to decomposition
Polymerization: Will not polymerize
Conditions to Avoid: Prolonged exposure to heat, open flames, acids, and oxidizers, avoid moisture ingress
Acute Toxicity: Oral LD50 (rat): 410 mg/kg, Dermal LD50 (rabbit): 230 mg/kg—shows substantial toxicity based on amount and exposure route
Skin Corrosion/Irritation: Causes severe irritation or burns
Eye Damage/Irritation: Can cause blindness if not quickly and thoroughly rinsed
Inhalation: Inhalation of dust or aerosols may cause nose, throat, lung irritation
Chronic Effects: Repeated exposure may cause dermatitis, no strong evidence linking to reproductive toxicity or carcinogenicity yet documented
Sensitization: Not reported as a skin or respiratory sensitizer in most guidelines
Ecotoxicity: Very toxic to aquatic organisms, can bioaccumulate in aquatic life, hazardous even at very low concentrations
Persistence and Degradability: Not readily biodegradable, remains in water and soil for extended periods
Mobility: Moderate in soil and water, significant run-off possible if released
Bioaccumulation: Has been shown to persist in aquatic organisms and the food chain
Other Adverse Effects: Disrupts bacterial and algae populations, alters aquatic ecosystem balance
Waste Disposal: Dispose of as hazardous waste in accordance with local, regional, national, and international regulations, do not pour into waterways or drains, consider incineration at approved chemical disposal facilities
Contaminated Packaging: Empty residues must be triple-rinsed, containers disposed of as hazardous waste or according to governmental regulations
