Emergency Overview: Pale to clear viscous liquid with slight to no odor, often supplied as an aqueous solution
GHS Classification: Not classified as hazardous according to OSHA or EU CLP regulations
Main Hazards: May cause mild eye irritation; skin contact can occasionally lead to redness in sensitive individuals; inhalation risk is low due to low volatility; not known to be mutagenic or cause chronic toxicity
Signal Word: None required
Hazard Statements: May cause mild mechanical irritation to eyes and skin
Precautionary Statements: Avoid contact with eyes, rinse thoroughly with water if contact occurs
Other Hazards: Spills may create a slip hazard on floors; product is often blended with water so concentration may affect hazard potential
Chemical Composition:
Diallyldimethylammonium chloride-acrylamide copolymer (concentration typically between 5%-10% by weight in solution), Water (balance)
Hazardous Ingredients: None in reportable concentrations
Additives: May contain trace preservatives or stabilizers as per manufacturer formulation
Impurities: Does not intentionally contain regulated impurities above threshold values; trace acrylamide levels generally below regulatory concern as monomer removal is controlled during production
Eye Contact: Rinse cautiously with clean water for several minutes, holding eyelids open; remove contact lenses if easily possible; seek medical attention if irritation develops or persists
Skin Contact: Wash thoroughly with soap and water; if redness or discomfort occurs, discontinue exposure and consult a healthcare professional
Inhalation: Move to fresh air; product is not expected to produce harmful vapor or fumes at ambient temperature
Ingestion: Rinse mouth with water; give water to drink in small sips if person is conscious; seek medical advice if symptoms persist or for larger amounts
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Unsuitable Extinguishing Media: Avoid high pressure water jets directed at surface
Specific Hazards: Product is not flammable; in a fire, containers may burst from heat; incomplete combustion may produce carbon or nitrogen oxides
Protective Equipment: Wear self-contained breathing apparatus and protective suit
Firefighting Instructions: Evacuate area; use water spray to cool containers; prevent runoff from reaching watercourses
Personal Precautions: Use personal protective equipment such as gloves and goggles to avoid direct contact
Environmental Precautions: Prevent product from entering drains, surface water, or soil
Spill Containment: Absorb spill with inert material (sand, earth, absorbent pads), collect in containers for disposal; wash residual area with water
Cleanup Procedures: Ventilate area; clean surfaces to avoid slipping hazard; dispose of waste material in accordance with local regulations
Precautions for Handling: Avoid contact with eyes and skin; handle in well-ventilated area; wash hands after use; avoid contamination of foodstuffs; keep containers tightly closed when not in use
Conditions for Storage: Store in cool, dry, ventilated place away from direct sunlight and incompatible materials such as oxidizing agents; product freezes below zero Celsius, which may change its physical properties; avoid temperatures above 40°C
Storage Materials: Keep in original packaging or suitable polyethylene or stainless steel containers; avoid long-term contact with metals prone to corrosion
Exposure Limits: No established occupational exposure limits; monitor air for nuisance particulates in industrial applications
Engineering Controls: Use local exhaust ventilation for large scale handling; avoid aerosol generation
Personal Protective Equipment:
Appearance: Clear to slightly hazy viscous liquid
Odor: Nearly odorless or faint characteristic smell
pH: Typically 5.0 – 7.0 (as supplied)
Melting Point/Freezing Point: Freezes below 0°C
Boiling Point: Approximately 100°C (water-based solution)
Flash Point: Not applicable
Evaporation Rate: Comparable to water
Flammability: Not classified as flammable
Vapor Pressure: Similar to water
Specific Gravity: 1.0 – 1.2
Solubility: Completely miscible in water
Partition Coefficient: Not determined
Auto-ignition Temperature: Not applicable
Decomposition Temperature: Above 200°C
Viscosity: Varies with grade; typically 1,000 – 10,000 cP
Chemical Stability: Stable under normal conditions of storage and use
Conditions to Avoid: Freezing temperatures, excessive heat, strong light exposure may lead to degradation
Incompatible Materials: Strong oxidizing agents, strong acids; avoid copper and aluminum for extended storage
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, nitrogen oxides possible on thermal decomposition
Polymerization: Does not undergo hazardous polymerization
Acute Toxicity: Oral LD50 (rat): >5,000 mg/kg; low toxicity by ingestion
Dermal Toxicity: Not expected to be absorbed through skin in harmful amounts
Eye Effects: May cause transient irritation upon direct contact
Skin Effects: Mild, non-sensitizing; reports of very slight redness in rare cases
Chronic Effects: Not expected under normal exposure scenarios
Genotoxicity/Carcinogenicity: Not classified as genotoxic or carcinogenic
Target Organs: None known for humans at typical exposure levels
Ecotoxicity: LC50 (28 days, fish): >100 mg/l (practically non-toxic)
Aquatic Fate: Dissolves and disperses in water; eventual biodegradation by aerobic microorganisms
Persistence: Moderate; slow removal in surface waters
Bioaccumulation: No significant bioaccumulation due to high water solubility
Mobility: Mobile in aquatic systems; diluted easily
Other Adverse Effects: High concentrations may cause localized foaming in surface water
Waste Disposal: Dispose according to local, state, and national regulations; non-hazardous waste in most locations
Methods: Prefer landfill or waste water treatment for dilute solutions; incineration if accepted
Contaminated Packaging: Triple rinse containers and offer for recycling or appropriate disposal
Precautions: Do not release into surface water or soils at undiluted concentrations
