Recommendation for Immediate Medical Attention: Direct prolonged eye or skin exposure; any respiratory distress or ingestion with symptoms requires urgent medical evaluation.
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide (CO2)
Unsuitable Extinguishing Media: Direct water jet could spread burning material
Hazards from Combustion: Fumes containing nitrogen oxides, carbon monoxide, carbon dioxide, amines.
Protective Equipment for Firefighters: Self-contained breathing apparatus (SCBA), full protective gear
Special Precautions: Cool exposed containers with water spray, avoid breathing fumes, evacuate area if uncontrollable fire develops.
Fire/Explosion Hazard: Material does not present unusual fire or explosion hazards under normal conditions, can become slippery from runoff which may present slip hazard for personnel.
Personal Precautions: Wear gloves, goggles, chemical-resistant clothing, limit unprotected personnel in the spill area, ensure adequate ventilation.
Environmental Precautions: Prevent entry into sewers, surface water, or groundwater, contain spill with dikes if safe to do so.
Methods for Cleaning Up: Absorb with inert material (sand, earth), collect residue into suitable container for disposal, wash contaminated surface with water and detergent.
Decontamination: Clean equipment with water, prevent spread of material by placing barriers, dispose processed waste through authorized channels.
Reporting: Notify authorities if spill could reach natural water systems or exceeds regulatory thresholds.
Handling: Use only with adequate ventilation, avoid contact with eyes or skin, wash hands thoroughly after use, do not eat or drink in handling area, keep containers tightly closed when not in use.
Storage: Store in cool, dry, well-ventilated area away from direct sunlight, sources of ignition, strong oxidizers, or acids; use corrosion-resistant containers; keep separate from food and drink.
Storage Temperature: 5°C to 30°C recommended, avoid freezing or excessive heat above 40°C.
Incompatibilities: Strong acids, strong bases, oxidizing agents; avoid storage with nitrites or nitrates.
Shelf Life: Typical product shelf life is one year if kept in unopened original containers and recommended conditions.
Exposure Limits: No established workplace exposure limit specific for this compound, follow general industry good practice.
Engineering Controls: Use local exhaust ventilation in areas of frequent or high-volume use, provide eyewash stations and safety showers in work areas.
Personal Protective Equipment (PPE): Chemical-resistant gloves (nitrile or neoprene), splash-proof safety goggles, protective clothing (long sleeves, lab coats or aprons), respiratory protection if mists generated.
Hygiene Measures: Wash hands and face thoroughly after handling, remove contaminated clothing promptly; do not reuse contaminated PPE.
Environmental Controls: Collect all process spillages, avoid aerosol generation; minimize rinse water discharge to environment.
Appearance: Pale yellow to amber liquid, may appear viscous at room temperature
Odor: Mild, characteristic, slightly amine-like
pH (concentrate): 9–11
Melting Point/Freezing Point: Not determined, generally remains liquid at room temperature
Boiling Point: Not readily available; decomposition may occur before boiling
Flash Point: > 100°C
Solubility: Soluble in water, forms emulsions
Density: 0.98–1.03 g/cm³
Viscosity: Typically 70–200 mPa.s depending on concentration
Vapor Pressure: Negligible under normal conditions
Partition Coefficient (log Kow): Not measured, expected to be relatively low due to surfactant nature
Decomposition Temperature: May decompose above 180°C with release of toxic gases.
Chemical Stability: Stable under recommended storage and handling conditions
Reactivity: Can react with strong oxidizing agents
Conditions to Avoid: Avoid excessive heat, direct sunlight, freezing, incompatible chemicals
Incompatible Materials: Strong acids, strong oxidizers, materials containing nitrites
Hazardous Decomposition Products: Nitrogen oxides (NOx), carbon oxides (CO, CO2), amines
Polymerization: No hazardous polymerization should occur under normal industrial conditions.
Acute Toxicity: Estimated LD50 (oral, rat) > 2000 mg/kg, low acute oral toxicity

Serious Eye Damage/Irritation: Causes moderate to severe irritation
Respiratory Sensitization: Not expected under normal conditions
Skin Sensitization: No reliable evidence of skin sensitization reported
Chronic Toxicity: No chronic effects known with recommended use; avoid frequent repeated direct exposure
Carcinogenicity, Mutagenicity, Reproductive Toxicity: No data available for carcinogenic, mutagenic, or reproductive effects in humans
Other Effects: High concentrations of fumes or vapors may cause drowsiness, headache in poorly ventilated areas.
Ecotoxicity: Toxic to aquatic life, especially fish and invertebrates (EC50 values for Daphnia and algae in the range of 1–10 mg/L)
Persistence and Degradability: Expected to be biodegradable under typical environmental conditions, may not degrade rapidly in all settings
Bioaccumulation Potential: Low based on surfactant properties, does not tend to build up in aquatic organisms
Mobility in Soil: High water solubility suggests good mobility in soil, possible leaching risk to groundwater
Other Adverse Effects: Potential for foaming in natural waterways, which can disrupt gas exchange for aquatic organisms
