Pictograms: Exclamation mark, environment
Precautionary Statements: Avoid breathing vapors, use only outdoors or in well-ventilated area, wear protective gloves and eye protection, avoid release to environment, wash hands thoroughly after handling
Substance: Pure Campholenic Aldehyde
Concentration: >99% (by weight)
Impurities: Trace amounts of related bicyclic aldehydes
Additives: None
Odor Threshold: Strong camphor-like scent at low concentrations
Inhalation: Remove to fresh air, provide oxygen if breathing is difficult, seek medical attention for persistent irritation or difficulty breathing
Skin Contact: Remove contaminated clothing, rinse affected area with soap and water for at least 15 minutes, seek care if irritation persists
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing and consult a physician
Ingestion: Rinse mouth, do not induce vomiting, give water to drink only if conscious, seek immediate medical attention
Note to Physician: Treat symptomatically; monitor for respiratory distress
Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam, or water spray
Unsuitable Media: Full water jet could spread the liquid
Specific Hazards: Vapors may form explosive mixtures with air, combustion produces irritating and toxic gases including carbon monoxide and carbon dioxide
Protective Equipment: Firefighters require self-contained breathing apparatus and full protective gear
Advice: Use water spray to cool containers near fire, avoid runoff entering drains or water bodies
Personal Precautions: Evacuate area, ventilate if possible, avoid breathing vapors, wear gloves, goggles, and mask
Environmental Precautions: Prevent leakage or spillage from entering drains, surface water, or soil
Spill Response: Absorb with sand, inert material, or specific spill kits, collect in container for disposal, clean contaminated area thoroughly
Emergency Procedures: Follow site-specific emergency protocols for chemical release
Precautions for Safe Handling: Handle in well-ventilated area, avoid contact with skin or eyes, keep away from ignition sources, ground containers during transfer
Hygiene Measures: Do not eat, drink, or smoke while handling, wash hands after use, remove contaminated clothing and equipment before entering break areas
Storage Recommendations: Store in tightly closed container in cool, ventilated, dry area, protect from sunlight and incompatible chemicals like strong oxidizers and acids, segregate from food and drink
Occupational Exposure Limits: No specific national exposure limits known; use general nuisance limits if around other organics
Engineering Controls: Use local exhaust ventilation or general mechanical ventilation to reduce vapor concentration
Personal Protective Equipment: Chemical-resistant gloves (nitrile, neoprene), safety goggles, lab coat or apron, flame-resistant clothing in bulk operations, organic vapor respirator when ventilation is inadequate
Environmental Controls: Prevent material and run-off from reaching sewers or surface water
Appearance: Colorless to pale-yellow clear liquid
Odor: Strong, camphoraceous
Melting Point: -12°C
Boiling Point: 208–210°C
Flash Point: 86°C (closed cup)
Autoignition Temperature: Not readily available
Explosive Limits: Data not conclusive
Vapor Pressure: Low at room temperature
Solubility: Insoluble in water, soluble in ethanol, diethyl ether, and oils
Relative Density: 0.97–0.99 g/cm3
Partition Coefficient (log Kow): Approx. 3 or higher (lipophilic)
Chemical Stability: Stable under normal conditions
Reactivity: Avoid contact with strong oxidizing agents, acids, and bases
Conditions to Avoid: Heat, sparks, open flame, static discharge, direct sunlight
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, low-molecular-weight hydrocarbons
Polymerization: No hazardous polymerization known under normal use
Acute Toxicity: Oral LD50 (rat): >2000 mg/kg; Inhalation LC50 (rat): not well-defined, suspected low hazard
Skin Irritation: Causes redness, dryness, may cause allergic reaction in sensitive individuals
Eye Irritation: Causes moderate irritation
Respiratory Effects: Vapor may irritate respiratory tract on high exposure
Chronic Exposure: No substantial evidence of long-term toxicity, potential for cumulative skin or eye irritation
Carcinogenicity, Mutagenicity, Reproductive Toxicity: No conclusive data to date
Toxicity: Toxic to aquatic life, acute LC50 (fish): 1–10 mg/L (estimated)
Persistence and Degradability: Moderately biodegradable, but caution around persistent environmental contamination
Bioaccumulation Potential: Moderate to high due to lipophilicity
Mobility in Soil: Low water solubility suggests limited mobility
Other Ecological Effects: Accumulation in aquatic environment can disrupt local ecosystems
Disposal Methods: Incinerate or incinerate with energy recovery in accordance with local, regional, and national regulations; do not release to sewer
Container Disposal: Triple rinse, puncture, and dispose of according to local environmental authority requirements
Contaminated Packaging: Dispose of as hazardous waste unless adequately cleaned
