Impurities: Minor manufacturing solvents or related compounds may appear at low levels depending on supplier
Additives: Some consumer formulations include inert carriers or emollients
Eye Contact: Rinse thoroughly with plenty of water for several minutes, remove contact lenses, keep eyelids open
Skin Contact: Wash affected area with soap and water, remove contaminated clothing, apply moisturizer to minimize dryness
Inhalation: Move affected individual to fresh air, monitor breathing, call a doctor if symptoms persist
Ingestion: Rinse mouth with water, do not induce vomiting, seek medical advice, give water to dilute if patient is conscious
Medical Attention: Seek medical assessment for prolonged irritation, persistent symptoms, or significant exposure; show this document to healthcare personnel
Personal Protective Measures: Use gloves and avoid direct contact if assisting
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, water spray for large fires
Specific Hazards: Burning releases toxic fumes including carbon oxides, nitrogen oxides, possible toluene derivatives
Protective Equipment: Firefighters use self-contained breathing apparatus, full protective gear
Special Precautions: Cool containers with water to prevent rupture, avoid smoke inhalation, control run-off to prevent environmental damage
Personal Precautions: Wear protective gloves, goggles, avoid breathing vapors, ventilate area, prevent skin and eye contact
Environmental Precautions: Prevent further leakage or spillage, do not let substance enter drains or watercourses; contain immediately with sand, earth, or inert absorbent
Cleanup Methods: Soak up with absorbent material, shovel into suitable disposal container; wash spill site thoroughly after collection
Reporting: Report significant spills as required by local and national regulations
Decontamination: Rinse area with water and detergent to remove residues after spill collection
Handling: Use in well-ventilated spaces, avoid inhaling vapors, avoid skin and eye contact, wash hands after use, do not eat, drink, or smoke nearby
Storage: Store in original containers tightly sealed, keep away from heat or open flames, store away from food and animal feed, avoid freezing or extreme temperatures, label containers clearly, limit access to trained personnel
Incompatible Materials: Strong oxidizers, acids, alkalis, avoid mixing with other chemicals unless compatibility is confirmed
Exposure Limits: No specific occupational exposure limits set by US OSHA or NIOSH for DEET, but consider keeping exposure as low as possible
Engineering Controls: Use local exhaust ventilation or fume hoods where vapor or aerosol formation is likely
Personal Protective Equipment: Wear chemical-resistant gloves (nitrile or neoprene), protective safety glasses or goggles, lab coat or apron to protect skin
Respiratory Protection: Use an approved respirator if exposure to vapors is unavoidable or ventilation is inadequate
Hygiene Measures: Wash hands and exposed skin after handling, do not reuse contaminated clothing, keep food and drink away from work area
Appearance: Colorless to pale yellow liquid
Odor: Slight, characteristic aromatic odor
Boiling Point: 288°C (550°F)
Melting Point: -45°C (-49°F)
Flash Point: 93°C (199°F), closed cup
Solubility: Slightly soluble in water, highly soluble in alcohols, ethers, and most organic solvents
Vapor Pressure: 0.001 mmHg at 25°C
Density: 0.995 g/cm³ at 25°C
pH: Not applicable (neutral, nonaqueous)
Partition Coefficient (log Kow): Around 2.2
Viscosity: Low; flows easily at room temperature
Chemical Stability: Stable under normal conditions for storage and use
Potentially Hazardous Reactions: Avoid strong oxidizers, acids, and bases; can react to release hazardous products if heated above decomposition point
Decomposition Products: Carbon monoxide, carbon dioxide, various oxides of nitrogen, possible toluene compounds
Polymerization: Not known to occur under standard storage or use
Storage Considerations: Keep from sources of ignition, avoid sunlight exposure for prolonged periods
Acute Toxicity: Oral LD50 (rat): 1800 mg/kg; Dermal LD50 (rabbit): >5000 mg/kg
Skin Corrosion/Irritation: Mild to moderate irritation possible with prolonged or repeated exposure
Eye Damage/Irritation: Causes mild eye irritation, can cause redness or watering
Respiratory Sensitization: Possible mild irritation of nasal passages and throat if inhaled in large amounts
Sensitization: Rare cases of allergic skin reactions reported
Chronic Effects: No evidence of carcinogenicity; large repeated exposures can sometimes affect the nervous system, manifested as headache, dizziness, restlessness
Medical Observation: Individuals with pre-existing skin, respiratory, or neurological conditions may be more susceptible to adverse effects
Environmental Fate: Moderately persistent, degrades slowly in soil and water; potential for accumulation in aquatic environments
Aquatic Toxicity: Fish LC50 (96 h, rainbow trout): approximately 75 mg/L; toxic to some aquatic invertebrates
Terrestrial Toxicity: Lower toxicity for birds and mammals at normal exposure levels
Bioaccumulation: Moderate potential based on log Kow; unlikely to bioaccumulate to high levels due to metabolism by most organisms
Other Adverse Effects: Can contribute to chemical oxygen demand in waterways, avoid release to environment
Soil Mobility: Moderate; some leaching may occur through sandy or permeable soils
Disposal Methods: Collect waste in labeled containers, deliver to licensed chemical disposal facility; do not dispose with household waste or pour down the drain
Contaminated Packaging: Dispose of using approved hazardous waste management company after thorough rinsing and removal of residue
Special Precautions: Incinerate or treat in accordance with applicable federal, state, and local environmental control regulations; consult local authorities for detailed requirements
