Inhalation: Move affected person to fresh air, provide oxygen if breathing becomes difficult, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, wash exposed skin area thoroughly with mild soap and water, seek medical attention for irritation that does not resolve
Eye Contact: Rinse eyes gently with plenty of water for at least 15 minutes, lift eyelids occasionally, seek medical attention if irritation continues
Ingestion: Rinse mouth, give plenty of water if person is conscious, do not induce vomiting, seek medical attention immediately
Suitable Extinguishing Media: Water spray, dry chemical powder, foam, carbon dioxide
Unsuitable Media: Direct jet of water may spread material
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, nitrogen oxides, possible formaldehyde fumes if strong heat
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective clothing
Special Precautions: Cool exposed drums or containers with water spray, stay upwind to avoid smoke
Personal Precautions: Wear gloves, goggles, suitable protective clothing to avoid skin and eye contact
Environmental Precautions: Prevent spilled liquid from entering drains, natural water flows, or soil, contain leaks with sand or inert absorbent
Cleanup Methods: Soak up with inert absorbent material such as sand or diatomaceous earth, collect spilled material in suitable containers for disposal, wash area with water after cleanup, ventilate area
Disposal of Cleanup Waste: Dispose of in accordance with local, regional, and national regulations
Handling: Use in well-ventilated areas, avoid contact with eyes and skin, keep containers tightly closed when not in use, avoid generating mists or aerosols
Hygiene: Wash hands thoroughly after handling, do not eat, drink, or smoke near the material
Storage Conditions: Store in original or compatible containers, keep in cool, dry, and well-ventilated location, protect from frost, humidity, and direct sunlight
Incompatible Materials: Strong oxidizing agents, strong acids, and anionic surfactants in high concentrations
Packaging: Prefer polyethylene, glass, or other resistant containers that prevent moisture ingress
Control Parameters: No established occupational exposure limits for Dodecyl Dimethyl Betaine
Engineering Controls: Use local mechanical ventilation or enclosed handling systems to minimize mist and vapor
Personal Protective Equipment: Chemical resistant gloves (nitrile, neoprene), safety goggles or face shield, protective clothing or aprons
Hygiene Measures: Keep work clothes separate, shower after work if contacted
Respiratory Protection: Use mask or respirator if mist forms or ventilation insufficient
Appearance: Clear to pale yellow liquid
Odor: Mild, almost odorless or faint amine-like
pH (1% solution): 6.0 – 8.5
Melting Point: Below room temperature
Boiling Point: Above 100°C (due to water content)
Flash Point: None to boiling (aqueous solution)
Solubility: Readily soluble in water
Relative Density: 1.00 – 1.10 g/cm³
Viscosity: Fluid, viscosity varies by temperature and dilution
Vapor Pressure: Negligible at room temperature
Partition Coefficient (log Kow): Not established, amphoteric structure leads to moderate partitioning
Chemical Stability: Stable under normal storage and handling conditions
Decomposition: Strong heating or fire may generate toxic fumes including carbon and nitrogen compounds
Polymerization: Does not polymerize
Incompatible Materials: Mixing with strong acids or oxidizers may cause reaction
Conditions to Avoid: Excessive heat, open flames, freezing temperatures
Acute Toxicity: Oral LD50 (rat) above 5,000 mg/kg, low acute toxicity
Skin Corrosion/Irritation: Moderate irritation possible with prolonged or repeated exposure
Eye Damage/Irritation: Causes significant irritation, no permanent damage at typical workplace concentrations
Respiratory Effects: Inhalation of mist may cause mild temporary discomfort to upper respiratory tract
Chronic Effects: No evidence of carcinogenicity, mutagenicity, or reproductive toxicity in available studies
Other Routes: Not a skin sensitizer in standard patch testing
Aquatic Toxicity: LC50 for fish above 1–10 mg/l, harmful to aquatic life at high concentrations
Persistence and Degradability: Readily biodegradable in natural environments, does not accumulate in the food chain
Bioaccumulation Potential: Low, surfactants rapidly degraded by microbes
Mobility in Soil: High due to water solubility; improper disposal may affect soil microfauna briefly
Other Hazards: Spills can result in foaming and oxygen depletion in watercourses
Waste Treatment: Send to licensed chemical disposal facility or treat in accordance with local wastewater laws
Container Disposal: Rinse thoroughly before recycling or disposal, puncture plastic drums to avoid reuse
Precautions: Avoid release to environment, never dump in drains or watercourses
