Name: Alkyl Dimethyl Amine Oxide
Common usage: Household cleaners, personal care products, industrial detergents
Physical form: Clear to pale yellow liquid
Odor: Mild, typical for surfactants with an amine structure
Family: Amine oxides, a group prized for their ability to boost cleaning performance in hard and soft water
Chemical formula: C14H31NO for lauryl dimethyl amine oxide (most used variant)
Molecular weight: 229.4 g/mol for lauryl derivative
Synonyms: N,N-dimethyldodecylamine N-oxide, C12 Amine Oxide
Main hazard: Irritation to skin, eyes, and respiratory tract
Signal word: Warning
Health risks: Redness or discomfort on contact, might worsen dermatitis in sensitive individuals
Inhalation hazard: Mist or vapor can irritate nose, throat, upper chest
Environmental hazard: Harmful to aquatic life at high concentrations, not rapidly degradable, but unlikely to bioaccumulate
Flammability: Not flammable in solution, but can support combustion when dehydrated
Chronic toxicity: Low under normal use, but repeated skin exposure sometimes causes sensitization
Active ingredient: Alkyl (C12–C18) dimethyl amine oxide, content typically ranges 27–35% in formulations
Water: Balance
Stabilizers: Trace, proprietary
Impurities: Low levels of primary amines or secondary amines
No regulated hazardous contaminants present above reportable thresholds
Eye contact: Flush gently with water for at least 15 minutes, remove contact lenses, seek medical advice if irritation persists
Skin contact: Wash area with soap and water, remove contaminated clothing
Inhalation: Move to fresh air, seek medical care if breathing gets difficult or coughing continues
Ingestion: Rinse mouth, drink water, avoid forced vomiting, get medical help if large volumes swallowed or symptoms worsen
Observe for delayed effects, especially in cases of concentrated chemical exposure
Extinguishing media: Use water spray, foam, dry chemical, or CO2
Special hazards: Smoke might carry irritant decomposition products like amines and oxides of nitrogen
Protective gear: Wear self-contained breathing apparatus and protective clothing
Thermal decomposition: Ammonia, amines, and carbon oxides released above 150°C
Fire spread: Low risk in solution; higher if residue dries out on absorbent surfaces
Spill cleanup: Absorb with sand or inert material, scoop into containers for disposal
Small spills: Mop up and flush area with plenty of water
Ventilation: Increase air flow to disperse vapors
Personal protection: Gloves, safety goggles, avoid breathing mist
Environmental caution: Prevent entry into drains, sewers, waterways
Wash spill site with detergent and water to remove residue
Handling: Use in well-ventilated areas, keep away from incompatible chemicals like strong acids or oxidizers
Personal safety: Avoid skin and eye contact, do not ingest or inhale concentrated product
Storage: Store in tightly sealed containers, out of direct sunlight, away from heat, at typical room temperature
Segregation: Keep apart from foodstuffs and incompatible materials
Labeling: Mark containers clearly, note hazards
Engineering controls: Local exhaust or general ventilation where mist or vapors could be generated
Protective wear: Chemical-resistant gloves (nitrile, rubber), safety goggles or face shield, lab coat or apron
Eye wash station: Should be available nearby
Respiratory protection: Not needed at normal concentrations; NIOSH-approved mask if aerosolized
Hygiene practices: Wash hands after use, remove contaminated clothes promptly
Occupational exposure limits: No established threshold limit value, but prudent avoidance of unnecessary exposure advised
Appearance: Clear to pale yellow liquid
Odor: Faint, amine-like
pH (10% solution): Around 6–8
Solubility: Completely miscible with water
Boiling point: Above 100°C due to water content
Flash point: None in aqueous solution
Density: Approximately 1.02 g/ml for commercial grades
Vapor pressure: Low at room temperature
Decomposition: Produces amines, oxides of nitrogen, and other volatiles with strong heat
Observation: Surfactant properties reduce surface tension significantly
Chemical stability: Stable under typical storage and use
Safety risk: Decomposes with strong oxidation, releases potentially hazardous gases upon burning
Incompatible materials: Strong acids, strong oxidizers, some reducing agents
Polymerization: Not known to occur
Storage life: At least one year in sealed container at room temperature
Acute oral toxicity: LD50 values in rats generally above 2000 mg/kg
Skin irritation: Moderate potential, especially with repeated exposure
Eye irritation: Can be severe depending on concentration
Chronic effects: No clear link to long-term systemic toxicity in humans at workplace levels
Sensitization: Low frequency, but possible with continued skin contact
Mutagenicity: No evidence supporting genetic risk in standard assays
Carcinogenicity: Not listed as a suspected carcinogen by major agencies
Biodegradability: Fair, moderate breakdown in standard wastewater treatment
Aquatic toxicity: LC50 to fish in low mg/L range, harmful at high concentrations
Persistence: Does not readily persist or bioaccumulate, but toxic to aquatic invertebrates above threshold amounts
Soil mobility: High, disperses easily in water
Environmental best practice: Prevent direct release to streams or lakes
Disposal: Small quantities diluted with lots of water can go to municipal sewer if local regulations allow
Industrial quantities: Send to licensed chemical waste processor
Container handling: Triple rinse containers, dispose as chemical waste
Do not incinerate pure product unless using approved facility
Local regulations: Always follow laws about disposal of cleaning chemicals
Reuse and recycling: Containers sometimes recyclable after thorough cleaning
DOT status: Not regulated as hazardous for ground or air shipping
UN number: Not classified under dangerous goods regulations
Packaging: Use leak-tight containers, protect from puncture or rupture, keep upright
Special precautions: Avoid stacking heavy items on top, label clearly
Damaged shipments: Inspect quickly, secure leaks
Regulatory listings: Not classified as hazardous by OSHA, EPA, or international bodies at typical concentrations
Labeling: Must reflect irritation and environmental hazard aspects
Safety Data Sheet: Required to be available at point of use in industrial settings
Right-to-know: Users should get direct access to health and environmental data
Registration: Registered for use in cleaners and cosmetics across North America, EU, and many Asia-Pacific countries
Reporting requirements: Not a listed substance on major threshold reporting lists under normal circumstances
Providing high-quality chemical products and logistics solutions for global trade partners.
