Chemical Formula: C7H12O2
Chemical Name: Allyl Butyrate
Common Uses: This colorless liquid brings a fruity aroma and lands in plenty of flavor fragrance projects, from enhancing certain beverages to lifting up the scents of soaps and detergents.
Appearance: Clear, oily liquid with a pineapple-like or fruity fragrance.
CAS Number: 2051-83-8
Scent Profile: Recognizable, strong, and sweet, something that tempts folks to overlook safety—not a good idea in any workplace.
Health Hazards: Skin and eye irritation turn up pretty fast, and expecting no reaction after heavy inhalation would be a mistake. Expect coughing, headaches, or worse if enough vapors build up.
Hazard Class: Flammable Liquid and Vapor. Not only is it easily ignited, but its vapors, heavier than air, stay low and can travel back to ignition sources.
Other Concerns: Breathing in too much can lead to central nervous system symptoms, including dizziness or drowsiness. Overexposure isn’t rare in small workshops, especially in warm conditions.
Main Component: Allyl Butyrate (often above 98 percent in its pure form)
Impurities: Trace amounts of related esters or alcohols might tag along, though nothing that significantly alters primary safety messages.
Mixture Risk: If blended into consumer or industrial products, check what else comes along; some added solvents or stabilizers can push fire risks higher.
Eye Contact: Rinse eyes gently yet thoroughly with plenty of water for several minutes; skip trying to neutralize, just flush and seek medical advice for redness or pain that hangs around.
Skin Contact: Remove contaminated clothing, wash skin with mild soap and water. It makes sense to avoid scrubbing since raw skin worsens the outcome.
Inhalation: Move to fresh air fast, and let rest replace panic. If the cough gets worse or breathing locks up, call for medical help right away.
Ingestion: Don’t chase with water or try to induce vomiting; medical support matters most. The risks from chemical burns can creep up if not treated quickly.
Suitable Extinguishing Media: Use foam, dry powder, or carbon dioxide. Water sprays dampen vapors but don’t expect them to put out flaming pools.
Special Hazards: Fierce heat brings out toxic fumes, including gases like carbon monoxide or irritating smoke.
Protective Equipment for Firefighters: Full gear, including a self-contained breathing apparatus, keeps responders safe in smoky or vapor-heavy air.
Firefighting Tactics: Keep containers cool with water from a safe distance. Direct spray may spread flaming liquid, so the right touch matters more than eagerness.
Explosion Risk: Closed containers exposed to fire can burst, turning a controlled event into chaos in seconds.
Personal Precautions: Good ventilation knocks down the risk. Protective gloves, goggles, and protective clothing are not for show.
Environmental Concerns: Spills threaten aquatic life, so block off drains and waterways. Absorb with sand, earth, or another inert material before cleanup.
Clean-Up Advice: Shovel or sweep up solids into suitable containers for disposal. Clean residue with a damp cloth. High vapor risk means avoiding sparks or flame anywhere near.
Emergency Measures: Evacuate non-essential workers and restrict area entry until cleanup finishes.
Handling: Work with Allyl Butyrate in well-ventilated places—a lesson you learn fast in any cramped lab or workshop. No eating, drinking, or smoking when handling. Minimize splashes, and close up containers promptly after use.
Storage: Keep in tightly closed containers, tucked away in a cool, dry spot with good airflow. Separate from heat, sparks, and open flames. Strong acids, alkalis, and oxidizing agents need to stay on the other side of a sturdy wall.
Transfer Risk: Ground and bond containers when transferring to prevent static; many have learned the hard way on dry winter days.
Safe Labelling: Clear labels, legible at a glance, prevent cross-contamination or mistakes during busy shifts.
Exposure Limits: Specific occupational exposure limits for Allyl Butyrate don’t turn up in every country. In absence of official values, treat low levels seriously.
Engineering Controls: Fume hoods and general ventilation help trap vapors before they reach breathing spaces.
Personal Protection: Safety goggles, resistant gloves (nitrile or butyl rubber do the job well), and long sleeves cut risk. Working with large amounts means considering an organic vapor respirator.
Hygiene: Wash hands thoroughly after handling. Clothing exposed to splashes needs changing promptly.
Environmental Monitoring: Check workplace air for build-up if volumes or frequency rise—never trust scent alone, as acclimation builds fast.
Boiling Point: Between 156 and 158 degrees Celsius means slow evaporation in cool rooms, but warm weather speeds up loss.
Melting Point: Dropping below -65 degrees Celsius, it stays liquid under normal storage.
Flash Point: Around 40 degrees Celsius in closed cup tests, underlining the risk from even moderate heat.
Odor: Sweet, fruity, sometimes overwhelming if left uncorked.
Vapor Pressure: Considerable at room temperature, giving rise to inhalation hazards.
Density: About 0.89 (water = 1), so spilled liquid floats and spreads.
Solubility: Limited in water, though it mixes quickly with most organic solvents.
Color: Clear or pale yellow, with oil-like consistency.
Stability: Stable at room temperature in absence of ignition sources.
Decomposition: Releases irritating or toxic gases under uncontrolled heat or fire.
Incompatible Materials: Avoid contact with strong oxidizers, acids, bases, or materials that can start unwanted reactions.
Polymerization: Doesn’t typically self-polymerize, yet mix-ups or heat may trigger unexpected chemistry in complex blends.
Risk Sources: Sunlight or high temperatures nudge it toward instability or increased vapor development.
Routes of Exposure: Skin, eyes, inhalation, and accidental ingestion.
Potential Acute Effects: Irritation of eyes, skin, and respiratory tract. In high concentrations, symptoms may escalate to nausea, headache, muscle weakness, or more severe central nervous system effects.
Chronic Effects: Evidence on long-term risks sits thin but repeated exposure ramps up chances of sensitization or dermatitis.
Reported Poisoning Cases: Uncommon in the public setting, though laboratory misuse or industrial incidents pop up in safety records every year.
Aquatic Toxicity: Harm to aquatic organisms counts as more than a theoretical risk. Esters in this family can disrupt fish and invertebrates in localized spills.
Persistence and Biodegradability: Biodegrades over time, but breakdown in waterways isn’t fast enough to ignore responsible disposal.
Bioaccumulation: Low to moderate risk, with rapid dilution if handled sensibly.
Other Environmental Effects: Runoff or large spills give off vapors that can travel and impact air quality, especially indoors or in industrial corridors lacking airflow plans.
Waste Handling: Treat as hazardous waste even in small batches. Pouring down drains invites regulatory trouble and pollution.
Preferred Methods: Incinerate in regulated facilities or deliver sealed containers for specialized disposal—never ordinary landfills.
Container Advice: If containers aren’t empty, keep them closed and label for hazardous content. Rinsing with water alone won’t neutralize leftovers.
Local Regulations: Follow municipal and national hazardous waste laws.
UN Number: Classified for flammable liquids.
Transport Hazards: Flammable, so keep away from heat, sparks, and fire during transit.
Packing Instructions: Leak-proof packaging with clear hazard identification cuts risk in transit.
Special Transport Measures: Vehicle ventilation prevents vapor buildup. Drivers and handlers need to know emergency procedures.
Regulation Coverage: Many countries flag Allyl Butyrate as hazardous under workplace safety, environmental protection, and transportation safety sets of rules.
Labels and Signage: Required hazard pictograms, including flame and exclamation mark, communicate risk at a glance.
Registration: Chemical inventories in Europe, North America, and many Asian countries log Allyl Butyrate, so notification or pre-market approval may apply.
Workplace Rules: Employers must train staff in safe handling, provide access to spill kits, and post safety instructions where exposure risk stays high.
