Chemical Ingredient: Tallowtrimethylammonium Chloride
CAS Number: 61789-97-7
Concentration: Typically present as greater than 85% active, remainder water or inert material
Impurities: May contain traces of tri- and di-methylammonium compounds depending on raw tallow sources and synthesis process.
Inhalation: Remove person to fresh air, keep at rest in comfortable breathing position. Get medical attention if symptoms persist.
Skin Contact: Wash skin with soap and plenty of water for at least 15 minutes. Remove contaminated clothing. If irritation occurs, seek medical care.
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, holding eyelids apart. Remove contact lenses if present. Seek medical advice.
Ingestion: Rinse mouth, do not induce vomiting, drink water to dilute. Call a toxicologist or doctor for further instructions. Never give an unconscious person anything by mouth.
Suitable Extinguishing Media: Use water spray, foam, dry chemical, or carbon dioxide extinguishers. Avoid high-pressure water jets.
Specific Hazards: Burning generates toxic fumes including nitrogen oxides and hydrogen chloride gas. Containers exposed to heat may burst.
Protective Equipment for Firefighters: Full protective gear and self-contained breathing apparatus (SCBA) recommended. Prevent runoff from entering drains or watercourses.
Special Firefighting Procedures: Cool exposed containers with water spray. Approach from upwind and evacuate surrounding area if fire occurs.
Personal Precautions: Wear appropriate personal protective equipment including gloves, goggles, and respiratory protection for powder.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Keep away from drains, surface water, and soil.
Spill Response: Absorb with inert material (sand, earth, vermiculite). Collect using non-sparking tools and transfer to suitable containers for disposal.
Cleanup Methods: Wash area with plenty of water after collection. Ventilate area and avoid dust formation if material is solid.
Safe Handling: Avoid contact with skin, eyes, and clothing. Do not breathe dust or mist. Use in well-ventilated area. Practice good industrial hygiene.
Storage Conditions: Store in tightly sealed containers in cool, dry, well-ventilated area away from direct sunlight, heat sources, and incompatible materials.
Storage Incompatibilities: Strong oxidizers, acids, and moisture extremes.
Special Considerations: Ensure containers are properly labeled. Avoid storing near food or consumables. Keep away from children and untrained individuals.
Engineering Controls: Use local exhaust ventilation and process enclosure to control exposure. Install emergency eyewash and safety showers where handling powder or solution.
Occupational Exposure Limits: No established exposure limits for this specific compound. Handle under established company health and safety guidelines.
Personal Protective Equipment: Use chemically resistant gloves (e.g., nitrile), goggles or face shield, and industrial coveralls. If ventilation inadequate, use NIOSH/MSHA approved respirator.
Hygiene Measures: Wash hands and face thoroughly after handling and before eating, drinking, or smoking. Remove contaminated clothing before entering communal areas.
Appearance: White to pale yellow waxy solid, can turn into a viscous liquid at elevated temperature.
Odor: Slight fatty or tallow odor.
pH (1% solution): 6.0 – 8.0
Melting Point/Freezing Point: 35 – 55°C
Boiling Point: Not available — decomposition expected before boiling
Solubility: Soluble in water, alcohol; insoluble in hydrocarbons.
Flash Point: > 93°C (closed cup)
Vapor Density: Not determined
Vapor Pressure: Negligible
Relative Density: 0.95 – 1.05 (at 25°C)
Partition Coefficient (log Kow): High, expected to bioaccumulate
Evaporation Rate: Not applicable
Decomposition Temperature: Begins to break down above 200°C
Chemical Stability: Stable under recommended storage and handling conditions.
Possibility of Hazardous Reactions: May react with strong oxidizing agents; does not polymerize.
Conditions to Avoid: Prolonged heat exposure, strong acids or alkalis, incompatible substances.
Hazardous Decomposition Products: Carbon oxides, nitrogen oxides, hydrogen chloride gas, other unidentified organic compounds.
Incompatibilities: Acids, oxidizing agents, and strong bases may cause hazardous conditions or decomposition.
Routes of Exposure: Skin and eye contact, inhalation of dust/mist, accidental ingestion.
Acute Effects: Skin and eye irritant, moderate oral toxicity, potential for chemical pneumonitis if aspirated.
Chronic Effects: Prolonged or repeated skin contact may cause dermatitis. No reliable evidence of carcinogenicity, mutagenicity, or reproductive toxicity with normal use.
LD50 (oral, rat): 500 – 2,000 mg/kg depending on formulation
Sensitization: Not sensitizing by dermal exposure under normal handling.
Symptoms of Exposure: Burning sensation, redness, coughing, nausea if mist is inhaled, vomiting if swallowed large quantity.
Ecotoxicity: Toxic to aquatic organisms, potential long-term adverse effects in the aquatic environment. LC50 (fish, 96 h) estimated at 1 – 10 mg/L.
Persistence and Degradability: Moderately biodegradable; quaternary ammonium structure can resist rapid breakdown in environment.
Bioaccumulation: Significant; cationic quats tend to bind to sediments and bioaccumulate in aquatic species.
Mobility in Soil: Low — adsorbs to soil particles and organic matter, reducing migration potential.
Other Adverse Effects: May cause foaming in wastewater treatment and reduce oxygenation in surface waters if released in large quantities.
Waste Handling: Collect and dispose as hazardous or special waste under local, regional, and national regulations. Do not mix with non-compatible substances.
Disposal Methods: Incinerate in approved facility or landfill with proper containment if allowed. Always neutralize if required before disposal.
Contaminated Packaging: Empty and clean containers may be recycled after decontamination. Cover label information and dispose according to regulations.
Special Precautions: Do not allow material to enter drains, sewers, or water bodies. Report large spills to relevant environmental authority.
