Formula: C13H26O3
Inhalation: Remove person to fresh air, seek medical attention for breathing difficulty, support vital functions. Possible symptoms: dizziness, headache, irritation to respiratory tract.
Skin Contact: Wash thoroughly with soap and water for at least fifteen minutes, remove contaminated clothing, seek medical attention for persistent irritation.
Eye Contact: Flush eyes immediately with plenty of water for at least fifteen minutes, lift eyelids, obtain medical help without delay.
Ingestion: Do not induce vomiting, rinse mouth with water, call poison control and obtain immediate medical care.
General Advice: Show this data sheet to the emergency medical personnel.
Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide; avoid water jet as it may spread the fire
Unsuitable Media: Water on bulk product may worsen the fire due to violent reaction with oxidizers
Special Hazards: Decomposition can release flammable gases, toxic fumes including carbon oxides and potentially explosive peroxides
Protective Equipment: Firefighters need self-contained breathing apparatus, full protective clothing
Further Advice: Remove containers from fire area if safe, cool adjacent containers with water spray, keep upwind
Personal Precautions: Evacuate area, ventilate, remove ignition sources, wear chemical protective equipment including gloves and goggles
Environmental Precautions: Prevent entry into sewers, waterways, soil. Notify authorities if release causes significant environmental impact
Cleanup Methods: Collect with inert, non-combustible absorbent (like vermiculite), place in secure container away from organic or combustible materials. Wash spill site after material pickup is complete
Disposal: Dispose as hazardous waste in line with local regulations, do not reuse empty containers
Decontamination: Wash contaminated surfaces thoroughly once material has been picked up
Handling: Use only in well-ventilated areas, keep away from heat, sparks, and open flames, avoid contact with skin, eyes, and clothing. Use spark-proof tools and proper grounding.
Storage: Store in original container, separate from incompatible substances such as acids, bases, reducing agents, and combustibles. Maintain storage temperatures as recommended by the supplier (usually cool and below 30°C, away from sunlight). Keep tightly closed and upright.
Special Notes: Storage rooms need effective ventilation, spill containment systems, and clearly marked emergency exits. Segregate from sources of ignition and incompatible materials.
Workplace Controls: Use exhaust ventilation, chemical fume hood, explosion-proof equipment, and local exhaust controls
Exposure Limits: No ACGIH or OSHA exposure limits established; minimize exposure by good practice
Personal Protection: Wear chemical-resistant gloves (nitrile or neoprene), splash-proof goggles and faceshield, flame-resistant clothing; use organic vapor respirator in circumstances of inadequate ventilation
Hygiene Measures: Wash hands and face before breaks and after handling; no eating, drinking, or smoking during handling
Environmental Controls: Use containment and scrubbers for process exhaust, avoid wastewater contamination
Appearance: Clear, colorless to pale yellow liquid
Odor: Faint, slightly pungent organic odor
pH: Not applicable
Melting Point/Freezing Point: Below -20°C
Boiling Point: Decomposes before boiling
Flash Point: Around 25°C (closed cup, can vary)
Evaporation Rate: Not determined
Flammability: Not directly flammable, but supports combustion
Vapor Pressure: Moderate at ambient temperature
Solubility: Insoluble in water, soluble in organic solvents
Partition Coefficient (n-octanol/water): Not determined precisely, but presumed to favor organic phase
Decomposition Temperature: Decomposes above 40°C, avoid heating
Viscosity: Low to medium viscosity
Density: Approximately 0.95 g/cm³ at 20°C
Chemical Stability: Sensitive to heat, light, and contamination; stable under recommended storage conditions. Peroxide bond can break, releasing energy
Reactivity: Reacts with strong acids, bases, reducing agents, and combustible materials. May generate heat and flammable byproducts
Hazardous Reactions: Violent decomposition possible under heat, pressure, or contamination; may detonate if confined
Conditions to Avoid: Excessive heat, sparks, static electricity, shock, friction
Hazardous Decomposition Products: Carbon oxides, small molecules, hazardous peroxides
Acute Toxicity: LD50 (oral, rat): estimated 800 mg/kg, indicative of moderate oral toxicity
Inhalation: May cause respiratory tract irritation, headache, nausea, drowsiness. Long exposure at high concentrations can affect central nervous system
Skin Contact: Causes moderate to severe irritation; prolonged exposure may produce dermatitis
Eye Contact: Serious irritation, redness, burning, possibly irreversible damage
Chronic Effects: Data on repeated dose toxicity is limited, but organic peroxides can sensitize skin or cause target organ effects at high doses
Carcinogenicity: Not classified as carcinogenic by IARC, OSHA, or NTP
Other Effects: Contains no known mutagens or reproductive toxicants at relevant concentrations
Aquatic Toxicity: Toxic to aquatic life, especially fish and invertebrates, with potential bioaccumulation risks
Persistence/Degradability: Organic peroxides degrade over time; breakdown products may persist if released to soil or water
Bioaccumulative Potential: Moderate, due to organic structure and poor water solubility
Mobility in Soil: Likely to be adsorbed to soil organic matter owing to low solubility. Risk of groundwater contamination if released
Other Adverse Effects: Spills can threaten aquatic systems, leading to fish kill events and disruption of ecosystems
Waste Treatment Methods: Collect waste in clearly labeled, sealed containers; isolate from incompatible and organic material
Incineration: Use licensed chemical incinerator with afterburner and scrubber, monitored by professionals
Land Disposal: Not recommended due to risk of fire and soil contamination
Special Instructions: Neutralize with reducing agents under expert supervision before disposal; comply with national hazardous waste regulations
Container Handling: Triple rinse, puncture, and dispose via hazardous waste contractor; never reuse for food or water storage
