Chemical Name: Alpha-Pinene Oxide
Concentration: ≥95% by weight
Impurities: Minor terpene oxides, residual solvents (less than 2%)
Additives: None listed for standard laboratory product
Ingredient Hazard: Main component responsible for all listed hazards—other impurities have low toxicological impact compared to alpha-pinene oxide itself.
Inhalation: Move person to fresh air immediately, loosen tight clothing, provide artificial respiration if breathing stops, seek medical attention for persistent symptoms
Skin Contact: Wash thoroughly with soap and water for at least 15 minutes, remove contaminated protective gear and wash before reuse, seek medical attention if irritation persists
Eye Contact: Rinse cautiously and continuously with water for 15 minutes, remove contact lenses if present, seek medical help promptly in case of burning or visual disruption
Ingestion: Rinse mouth with water (if person is conscious); never induce vomiting; seek immediate medical attention for possible toxic effects or persistent symptoms
Most Important Symptoms: Burning in airways or eyes, ringing in ears, upset stomach; rare cases show allergic reactions.
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, sand, alcohol-resistant foam
Unsuitable Extinguishing Media: Direct water spray could cause fire to splatter
Special Hazards: Produces dense, choking smoke and irritating vapors under fire, risk of explosion if stored near oxidizers
Protective Equipment for Firefighters: Self-contained breathing apparatus, full firefighting protective wear, avoid inhaling fumes
Advice for Firefighters: Contain runoff with sand or earth, keep drums cool with water spray from safe distance, ventilate area after fire
Combustion Products: Carbon monoxide, carbon dioxide, volatile organic compounds, possibly other aldehydes or organic acids.
Personal Precautions: Evacuate unprotected personnel, ventilate affected area, avoid contact with skin, eyes, and clothing
Protective Measures: Wear gloves, splash-proof goggles and chemical-resistant apron, breathing protection if ventilation is insufficient
Environmental Precautions: Prevent undiluted liquid from entering drains, sewers, groundwater, or open bodies of water—stop flow with inert absorbent like sand
Containment: Use dikes or absorbent barriers, collect up spillage into clearly labeled chemical disposal containers, seal immediately after collection
Clean-Up Methods: Wipe small spills with absorbent towel or inert media, larger spills require specialized suction or pump and secondary containment, dispose per local regulations.
Handling: Maintain strict hygiene practices, avoid all direct contact with product, use in ventilated space or under fume hood, no open flames or ignition sources
Precautions: Never eat, drink, or smoke near product, keep away from incompatible materials like strong oxidants
Storage Conditions: Keep container tightly closed in a cool, ventilated, fire-proof area, store away from light to prevent degradation, label all hazardous contents clearly
Incompatible Materials: Strong acids, strong bases, oxidizers, peroxides
Container Materials: Store in amber glass or non-reactive high-density polyethylene; metal containers (other than stainless steel) could corrode or leak
Storage Temperature: Ideal storage below 25°C, avoid freezing or excessive heat.
Occupational Exposure Limits: No established OSHA or ACGIH limits; good hygiene and engineering controls are critical
Technical Controls: Laboratory-style chemical fume hoods, local exhaust ventilation reduce vapor build-up
Personal Protection: Chemical-resistant gloves (such as nitrile or butyl), splash-proof goggles, long sleeves, lab coat; wear respiratory protection if vapor exposure suspected
Hygiene Measures: Wash hands before eating, smoking, or handling restroom breaks; keep contaminated clothing segregated
Monitoring: Regular air sampling in case of bulk handling; visual inspection for leaks or degradation of storage containers.
Appearance: Clear to pale yellow liquid
Odor: Distinct turpentine, pine-like
Odor Threshold: Noticeable at low ppm concentrations
Molecular Weight: 152.23 g/mol
Boiling Point: 60°C at reduced pressure; decomposes at higher atmospheric pressure
Melting Point: -40°C
Flash Point: About 55°C (closed cup)
Auto-ignition Temperature: Estimated above 220°C
Explosion Limits: Vapors may form explosive mixture with air
Density: Around 0.94 g/cm³ at 20°C
Solubility: Practically insoluble in water, mixes well with most organic solvents
Viscosity: Low, fluid liquid
Evaporation Rate: Moderate, subject to ambient conditions.
Chemical Stability: Stable under recommended storage, but forms peroxides over long exposure to air and light
Reactivity: Undergoes exothermic reactions with strong acids, bases, or oxidizing agents
Conditions to Avoid: Excessive temperatures, direct sunlight, open flames
Incompatible Materials: Strong oxidants, acids, bases, peroxides
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, aldehydes, small amounts of other organic vapors
Danger of Polymerization: Not expected under normal storage.
Routes of Entry: Inhalation, skin absorption, eye contact, ingestion
Acute Toxicity: LD50 oral (rat): 2100 mg/kg; inhalation LC50 data limited, could cause narcosis at higher concentrations
Symptoms of Overexposure: Headache, skin or eye inflammation, dizziness, loss of coordination, stomach upset
Skin Sensitization: Can provoke allergic reactions after repeated exposure
Chronic Effects: Repeated, long-term exposure associated with possible nervous system effects; insufficient data for carcinogenicity
Specific Target Organ Toxicity: May affect central nervous and respiratory systems
Mutagenicity/Carcinogenicity: Not known as human carcinogen; limited mutagenicity data; handle with caution in absence of long-term studies
Medical Conditions Aggravated: Pre-existing dermatitis, asthma, or respiratory illness could worsen symptoms.
Toxicity to Aquatic Life: Harmful to fish and aquatic invertebrates, low LC50 values indicate potential environmental hazard
Persistence and Degradability: Moderately biodegradable over time, but can persist under low-oxygen or anaerobic conditions
Bioaccumulative Potential: Moderately bioaccumulative; could persist in organisms due to slow metabolic breakdown
Mobility in Soil: Strongly adsorbed to organic matter, could migrate if spilled near water sources
Other Adverse Effects: Volatile, can contribute to low-level ozone and atmospheric reactivity.
Environmental Precautions: Keep out of surface water, groundwater, and sewage systems; long-term effects possible in aquatic food chains.
Waste Treatment Methods: Hand over to licensed hazardous waste disposal contractor, use incineration with appropriate gas scrubbing; do not dump in drains, waterways or regular waste bins
Container Disposal: Rinse empty drums or bottles with suitable solvent and treat as hazardous waste; puncture only if authorities allow
Disposal Precautions: Follow all local, state, and federal regulations for chemical disposal; collect larger waste in sealed, clearly marked containers; avoid release to environment.
Special Handling: Do not attempt to neutralize or destroy with household chemicals.
