Other Ingredients: Water as diluent, no relevant hazardous additives reported
Inhalation: Move person to fresh air, seek medical advice if breathing becomes difficult
Skin Contact: Remove contaminated clothing, wash exposed areas with soap and water, consult a physician if irritation occurs
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present, get medical attention if irritation persists
Ingestion: Rinse mouth, drink water if conscious, do not induce vomiting, consult a healthcare provider if feeling unwell
Most Important Symptoms: Redness, mild inflammation, respiratory discomfort
Suitable Extinguishing Media: Water spray, carbon dioxide, dry chemical, foam
Unsuitable Media: High-pressure water jets may spread spilled product
Specific Hazards: Product does not burn readily; thermal decomposition may release small amounts of toxic gases such as nitrogen oxides and hydrogen chloride
Protective Equipment: Firefighters need self-contained breathing apparatus and protective clothing to guard against smoke, fumes, and splashes
Advice for Firefighters: Stay upwind, cool containers with water spray to prevent heating and pressure buildup
Personal Precautions: Use personal protective equipment to prevent skin and eye contact, ventilate area
Environmental Precautions: Prevent further leakage or spillage if safe, do not let large quantities enter drains or watercourses
Methods for Cleanup: Absorb with inert material like sand or earth, collect in appropriate containers for disposal, clean spill area with plenty of water to remove residues
Additional Steps: Notify authorities if spill has impacted environment or water supply
Handling: Avoid direct contact, wear gloves and eye protection, prevent aerosol or mist formation, avoid eating or drinking while using
Storage Conditions: Keep containers tightly closed, store in a cool, dry, well-ventilated place, keep out of reach of children
Compatible Materials: Store in containers made of polyethylene, glass, or stainless steel; separate from strong oxidizing agents
Storage Temperature: 5–35°C, prevent freezing and overheating
Special Considerations: Avoid sources of extreme heat, direct sunlight, and moisture contamination in storage
Occupational Exposure Limits: No established limits for PolyDADMAC
Engineering Controls: Provide local exhaust ventilation where aerosol or mist may form
Personal Protective Equipment (PPE): Wear nitrile or neoprene gloves, chemical safety goggles, lab coat or overall, use a respirator if aerosolized
Hygiene Measures: Wash hands and face thoroughly after handling, remove contaminated clothing and launder before reuse
Environmental Controls: Prevent effluent discharge to natural waters without appropriate treatment
Appearance: Clear, colorless to pale yellow liquid
Odor: Slight, amine-like odor
pH: 4.5–7.0 (aqueous solution)
Melting Point/Freezing Point: Below 0°C for aqueous solution
Boiling Point: Above 100°C (solution depends on water content)
Flash Point: Not applicable
Solubility: Completely soluble in water
Density: 1.05–1.20 g/cm³ (depends on concentration)
Viscosity: Varies by solution strength
Vapor Pressure: Similar to water
Other Properties: Non-flammable, does not support combustion, negligible volatility
Chemical Stability: Stable under recommended storage and use conditions
Reactivity: Unreactive with most substances under ambient temperature
Conditions to Avoid: Avoid exposure to freezing temperatures or direct sunlight
Incompatible Materials: Strong oxidizing agents, anionic polymers (may cause precipitation or loss of effectiveness)
Hazardous Decomposition Products: May generate hydrogen chloride and nitrogen oxides if heated to decomposition or burned
Polymerization: Not likely under normal handling or use
Acute Toxicity: Oral LD50 in rats > 5000 mg/kg (relatively low toxicity)
Skin Irritation: Mildly irritating to skin on contact in animal tests
Eye Irritation: Slight irritation possible, especially with sensitive individuals
Sensitization: No evidence of sensitizing in available studies
Chronic Effects: Repeated contact may cause dryness or cracking of skin
Carcinogenicity: No components listed by NTP, IARC, OSHA as carcinogenic
Other Information: No data indicating reproductive or developmental effects; ingestion of large quantities should be avoided to prevent nausea or indigestion
Ecotoxicity: Low toxicity to aquatic life at normal concentrations used in wastewater and water treatment
Biodegradability: Biodegrades slowly, may bind to sludge or sediment
Bioaccumulation Potential: Unlikely to bioaccumulate due to high water solubility and large polymer size
Mobility in Soil: Limited, tends to adsorb to soil surfaces
Aquatic Effects: High doses could affect microorganisms or aquatic invertebrates
Environmental Fate: Most of the product will be removed during waste treatment by adsorption to solids
Waste Treatment Methods: Dispose according to local, national, or regional laws
Product Disposal: Treat effluent with appropriate biological or chemical treatment, avoid direct discharge to surface waters
Waste Packaging: Triple rinse empty containers, then recycle or landfill according to regulations
Special Disposal Precautions: Do not mix with incompatible wastes such as strong oxidants, avoid open dumping or uncontrolled landfilling
Disposal Code: Contact local waste authority for appropriate classification
UN Number: Not regulated under most transport rules
