Composition / Information on Ingredients

Main Component: Cassia Oil (Cinnamomum cassia)
Major Constituent: Cinnamaldehyde (60–90%)
Other Components: Coumarin, cinnamyl acetate, cinnamic acid, benzaldehyde, linalool, eugenol (in small concentrations)
Impurities: Trace organic and natural volatile substances

First Aid Measures

Inhalation: Move affected person to fresh air, seek medical attention if irritation or respiratory symptoms persist
Skin Contact: Remove contaminated clothing, wash skin with water and soap for several minutes, consult a physician if symptoms continue
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, remove contact lenses, seek medical help
Ingestion: Rinse mouth, do not induce vomiting, call poison control or a medical professional immediately

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide
Unsuitable Media: Water jet may spread fire
Special Hazards: Vapors may form explosive mixtures with air, combustion may release toxic fumes including carbon oxides
Advice for Firefighters: Wear self-contained breathing apparatus and protective clothing, evacuate area if needed; cool exposed containers with water spray

Accidental Release Measures

Personal Precautions: Remove ignition sources, ensure adequate ventilation, avoid inhalation or skin contact, use personal protection
Environmental Precautions: Prevent further leakage or spillage, do not allow product to enter drains, surface water, or soil
Methods for Clean-Up: Absorb with inert material (sand, earth), use non-sparking tools, place in suitable closed container for proper disposal; ventilate affected area

Handling and Storage

Safe Handling Recommendations: Handle in well-ventilated areas, avoid open flames and heat sources, use personal protective equipment, practice good hygiene
Storage Conditions: Store in a tightly sealed, light-resistant container in a cool, dry, well-ventilated area away from strong oxidizers and ignition sources
Incompatible Materials: Oxidizing agents, acids, strong bases
Special Requirements: Ground and bond containers during transfer, keep away from food and drinks

Exposure Controls and Personal Protection

Occupational Exposure Limits: Cinnamaldehyde TLV/TWA not established; use workplace ventilation
Engineering Controls: Use fume hoods or local exhaust ventilation
Personal Protective Equipment (PPE): Chemical-resistant gloves (nitrile suggested), splash-resistant safety goggles, long-sleeved protective clothing; in high vapor settings, use NIOSH-approved respirator
General Hygiene: Wash hands before eating or drinking, avoid skin and eye contact, keep contaminated clothing separate
