Inactive Ingredients: Water to balance percentage (up to 40%)
Impurities: Trace levels of residual monomers and side products from manufacturing, tested to remain below specified industrial thresholds
Eye Contact: Rinse cautiously with water for up to 15 minutes, hold eyelids open, remove contact lenses if present and easy
Inhalation: Move person to fresh air, monitor breathing, seek medical attention for symptoms like cough or shortness of breath
Skin Contact: Remove contaminated clothing immediately, rinse affected skin area with soap and water for several minutes, seek help if irritation or immune response persists
Ingestion: Rinse mouth, do not induce vomiting, seek prompt medical care, information about ingestion and chemical identity for provider
Symptoms of Overexposure: Redness, swelling, itching, possible allergic reactions, gastrointestinal discomfort if swallowed
Suitable Extinguishing Media: Water fog, alcohol-resistant foam, dry chemical powder, carbon dioxide
Unsuitable Media: High-pressure water jets may cause product to spread
Special Hazards: Incomplete combustion yields toxic gases including hydrogen chloride, nitrogen oxides, irritating organic vapors
Protective Equipment and Precautions: Self-contained breathing apparatus, full protective gear for responders
Other Fire Considerations: Containers exposed to heat may rupture, spillage increases slip hazard on floors
Personal Precautions: Wear gloves, goggles, chemical-resistant clothing, prevent inhalation and skin contact
Environmental Precautions: Prevent run-off into drains, sewers, surface water due to aquatic toxicity
Cleanup Methods: Contain and absorb spills with inert material like sand or earth, collect in labeled waste containers, clean area with water to prevent residue buildup
Notification: Report large spills to relevant authorities following local guidelines and threshold requirements
Handling: Use only in well-ventilated spaces, keep away from incompatible materials such as strong oxidizers and bases, avoid any direct contact
Storage Conditions: Store in cool, dry, ventilated areas, keep containers tightly closed and labeled, protected from direct sunlight and heat sources
Incompatibilities: Oxidizing agents, reducing agents, strong acids, metals may corrode in presence of chloride ions
Special Considerations: Install secondary containment to minimize risk from leaks or spills, access to eyewash stations and emergency showers
Engineering Controls: Local exhaust and general dilution ventilation systems
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), splash-proof goggles, face shield, lab coat or chemical coveralls
Respiratory Protection: Approved respirator if airborne concentrations exceed permissible exposure limits or if irritation occurs
Exposure Limits: OSHA PEL and ACGIH TLV for general dusts and vapors followed if specific DMDAAC limits undefined
Hygiene Measures: Wash hands thoroughly before eating, drinking, or smoking, decontaminate protective gear after use
Appearance: Clear to pale yellow liquid, viscous
Odor: Mild, ammoniacal scent
Odor Threshold: Not experimentally established for DMDAAC
pH: Range: 5.0–7.0 (as supplied aqueous solution)
Melting Point/Freezing Point: Below -5°C
Boiling Point: Over 100°C (aqueous solution factor)
Flash Point: Not flammable under standard testing
Evaporation Rate: Slower than water
Flammability: Non-flammable, but may burn with external source
Vapor Pressure: Low at room temperature
Solubility in Water: Fully miscible
Partition Coefficient (n-octanol/water): Negligible, favors aqueous phase
Decomposition Temperature: Above 180°C releases toxic gases
Viscosity: Viscous in concentrated solution, varies with dilution
Chemical Stability: Stable under normal conditions, avoid uncontrolled heating above 140°C
Possible Reactions: Strong oxidizers and bases may lead to hazardous decomposition
Hazardous Decomposition Products: Hydrogen chloride, dimethylamine, carbon oxides, nitrogen oxides
Polymerization: No risk of uncontrolled polymerization in storage or handling
Incompatible Materials: Strong acids, alkalis, oxidizing solutions, reactive metals like aluminum and zinc
Other Reactivity: Avoid contact with substandard plastics or metals liable to corrosion in presence of chlorides
Acute Toxicity: Oral LD50 for rats approximately 200–1000 mg/kg, moderate toxicity
Skin Contact: Causes moderate irritation, may cause sensitization on repeated or prolonged exposure
Eye Contact: Causes significant irritation, possible chemical burns
Inhalation: Vapors or mists may irritate respiratory tract, limited risk at ambient temperatures unless sprayed or heated

Ecotoxicity: Toxic to aquatic life, LC50 for fish (96h) between 30–100 mg/L, EC50 for daphnia 20–50 mg/L
Persistence and Degradability: Slowly biodegradable, potential for accumulation in sediment, breaks down under aerobic conditions
Bioaccumulation Potential: Low as DMDAAC is water-soluble, low log Kow
Mobility in Soil: High mobility due to solubility in water, potential for groundwater contamination
Other Harmful Effects: Discharges into biological treatment plants may disrupt microbial activity
