Name: trans-Cinnamaldehyde
Other Names: Cinnamic aldehyde
Chemical Formula: C9H8O
CAS Number: 104-55-2
Appearance: Yellowish liquid with a strong, sweet cinnamon-like odor
Common Uses: Flavoring in foods, ingredient in fragrances, and intermediate in chemical synthesis
Origin: Derived mainly from cinnamon bark oil, but also produced synthetically
Main Hazards: Irritant to eyes and skin, may cause allergies
Health Risks: Breathing in vapors or contact with the substance potentially triggers respiratory or skin sensitization; can provoke allergic reactions after repeated exposure
Warning Symbols: Classified as harmful, with a risk of serious eye damage and sensitization
Environmental Dangers: Harmful to aquatic organisms, potential for negative impact even with small releases into waterways
Chronic Risks: Some evidence shows repeated handling might bring about dermatitis and respiratory discomfort
Main Component: trans-Cinnamaldehyde: 98% or higher, depending on source
Impurities: Other related aromatic aldehydes sometimes present in minor quantities
Additives: Purity varies, but reputable sources deliver product with limited or no additives
Inhalation: Move to fresh air, support breathing, and seek medical help if coughing or irritation persists
Skin Contact: Wash off thoroughly with soap and water; remove contaminated clothing
Eye Contact: Flush with running water for at least 15 minutes, get medical attention if irritation continues
Swallowing: Rinse mouth, do not induce vomiting, and seek medical advice if feeling unwell
Warnings: Immediate professional intervention helps reduce irritation and allergy risk, especially in sensitive individuals
Fire Risks: Flammable liquid and vapor
Combustion Byproducts: Can release smoke, carbon monoxide, and irritating fumes
Extinguishing Tools: Use CO2, dry chemical powder, or foam; water may spread the fire if sprayed directly
Precautions: Approach from upwind; wear protective gear to guard against fumes
Explosion Potential: Vapor mixtures may ignite with air in specific situations, so ventilated detection matters
Small Spills: Absorb with inert material such as sand or earth, clean up promptly
Large Spills: Block off area, contain spill, and use cleanup crews with proper gear
Ventilation: Ensure area is well-ventilated to prevent inhaling concentrated vapor
Protective Measures: Wear gloves, goggles, and suitable clothing to prevent exposure
Environmental Care: Prevent entry to waterways or drains to limit spill impact on ecosystems
Handling: Use only in well-ventilated settings, wear personal protection as routine
Storage: Keep in cool, sealed containers away from heat, sparks, or flames
Separation: Separate from incompatible substances, especially strong oxidizers and acids
Container Integrity: Use containers of appropriate materials to avoid leaks or chemical reaction
Spill Prevention: Regular checks of container seals and careful transfer processes reduce accident risk
Engineering Controls: Use exhaust ventilation or local capture systems when used in bulk
Protective Clothing: Wear gloves made of chemical-resistant material, goggles or face shield, and protective apron or coat
Respiratory Protection: Organic vapor respirators recommended if ventilation is lacking or handling in bulk
Workplace Limits: No official occupational exposure limits in many regions, but prudent operations require regular air checks
Hygiene: Wash hands after handling, keep contaminated clothing separate until laundered
Form: Oily liquid
Color: Pale yellow to yellow
Odor: Strong, sweet-spicy cinnamon
Boiling Point: Around 248°C
Melting Point: Approximately -8°C
Solubility: Insoluble in water, readily mixes with alcohol and organic solvents
Density: Roughly 1.05 g/cm³
Vapor Pressure: Low at room temperature
Flash Point: About 71°C
Chemical Stability: Stable under common storage conditions
Reactive Substances: Contact with strong oxidizing agents and acids brings possibility of hazardous reaction
Hazardous Decomposition: Can break down to carbon monoxide, carbon dioxide, and irritating fumes if overheated or burned
Conditions to Avoid: Takes minimal effort to keep away from ignition sources or extreme temperatures
Main Routes: Inhalation, skin, and eye contact
Short-Term Exposure: Causes irritation, can provoke skin allergies on repeated exposure
Long-Term Exposure: Prolonged skin contact links to eczema and chronic dermatitis for sensitive individuals
Oral Toxicity: Moderate toxicity in lab animals; not advisable for oral use in quantities above flavoring levels
Mutagenicity/Carcinogenicity: No strong evidence points to cancer risk but caution around chronic exposure stays justified
Reproductive Effects: Current research hasn’t shown significant reproductive harm, yet responsible handling reduces all risks
Ecotoxicity: Toxic to aquatic life, especially fish and invertebrates
Mobility: Tends to evaporate from surface, but if spilled into water, poses threat due to slow breakdown
Persistence/Degradability: Biodegrades over time, but not fast enough to avoid harm in concentrated spills
Bioaccumulation: Low risk of accumulation in living organisms at typical exposure levels
Best Practices: Take waste to licensed chemical disposal facilities
Environmental Safety: Never pour waste down a drain or throw out with regular garbage
Container Rinsing: Wash empty containers thoroughly and handle rinse water as hazardous
Local Rules: Follow area-specific hazardous waste regulations, which often require documentation and approved handlers
Classification: Flammable liquid
Packing Considerations: Use UN-approved containers suited for flammable substances
Accident Protocols: Emergency kits and clear labeling on every shipment reduce mishap chances
Spill Response: Train transport staff on quick containment and evacuation procedures if a leak occurs
Global Status: Regulated as a hazardous chemical in many jurisdictions
Workplace Safety: Subject to general chemical handling laws, including training and labeling requirements
Transport Laws: Recognized as a regulated item under most national and international guidelines for flammable materials
Environmental Regulation: Controlled for release into waterways due to aquatic toxicity
Consumer Product Limits: Permitted in foods and fragrances within strict concentration boundaries, as set by food safety agencies
