Chemical Name: Epigallocatechin gallate
Synonyms: EGCG
Chemical Formula: C22H18O11
Appearance: Light yellow powder
Odor: Odorless
Use: Found in green tea and sometimes added to dietary supplements for its antioxidant properties
Health Hazard: Might cause irritation if it gets in the eyes, on the skin, or if inhaled
Environmental Hazard: Reports indicate limited impact if small amounts get into soil or water, though best practice is to avoid unnecessary environmental release
Fire Hazard: Dust can present a small risk of explosion if allowed to accumulate in confined spaces
Label Elements: Hazard pictograms rarely assigned, but common sense suggests using general caution iconography in a workplace setting
Main Ingredient: Epigallocatechin gallate
Concentration: Purity typically exceeds 90% in commercial samples
Impurities: Trace amounts of other catechins, moisture sometimes present if packaging is compromised
Eye Contact: Prompt washing with plenty of water, eyelids pulled apart to flush thoroughly
Skin Contact: Wash with soap and water; remove contaminated clothing if irritation appears
Inhalation: Move to fresh air, seek medical attention if coughing or discomfort persists
Ingestion: Rinse mouth with water, seek advice from a physician if any unusual symptoms develop
Suitable Extinguishing Techniques: Use water spray, foam, dry chemical, or carbon dioxide
Specific Hazards: Product can burn and release carbon monoxide or carbon dioxide, avoid breathing smoke
Protective Equipment: Firefighters should use self-contained breathing apparatus and full protective clothing, especially in poorly ventilated spaces
Precautions: Avoid generating dust, ventilate the area if any is present
Personal Protection: Wear gloves, goggles, and a dust mask or respirator; refrain from eating or drinking near spills
Clean-Up Methods: Sweep material up carefully into a container for proper disposal, wash area with plenty of water
Handling: Use local exhaust if needed, minimize dust, avoid direct skin or eye contact, handle containers gently
Storage: Keep container tightly closed in a cool, dry place, away from light and sources of ignition; segregate from oxidizers and acids
Engineering Controls: Work with good ventilation or fume hood, install dust collection if handling large volumes
Personal Protective Equipment: Gloves, safety glasses, dust masks provide reasonable safety
Hygiene: Wash hands after use, keep food and drink away from work area, change clothes if contamination occurs
Physical State: Solid powder
Color: Pale yellow to light brown
Melting Point: Around 220°C (decomposes on melting)
Solubility: Slightly soluble in water, more soluble in alcohol
Odor: No significant odor
Vapor Pressure: Not volatile under standard conditions
Chemical Stability: Stable under recommended storage conditions, sensitive to light, heat, and air exposure
Potentially Incompatible Materials: Strong oxidizing agents, acids
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide during combustion
Routes of Exposure: Eyes, skin, inhalation, ingestion
Acute Effects: Eye or skin irritation, sore throat or coughing if dust is inhaled
Chronic Effects: Studies in lab animals suggest high doses over time might affect the liver, though normal dietary intake shows little risk
Carcinogenicity: No evidence links EGCG to cancer risk at levels found in food or supplements based on available studies
Mutagenicity: Lab tests give mixed results, so handling with care remains a smart approach
Ecotoxicity: Not especially toxic to aquatic life, but large spills might have temporary local effects
Persistence and Degradability: Breaks down slowly in the environment, usually doesn’t persist
Bioaccumulation: Tends not to build up in the tissues of organisms
Safe Disposal: Collect waste material and send to a licensed chemical disposal facility
Disposal of Containers: Triple rinse bottles or bags, then follow local regulations for chemical waste
Avoid: Do not dump in drains, sewers, or water courses
General Guidance: Store in tightly closed containers, transport in dry, cool conditions
Packing: Protect from moisture and excessive heat, keep containers upright and sealed
Shipping Regulations: Not considered hazardous for general transportation, no special shipping hazard noted for small laboratory or retail quantities
Local and National Guidelines: EGCG falls under regulations that apply to food additives or dietary supplements in many countries
International Standards: Not listed as a hazardous substance by main regulatory agencies such as OSHA, IARC, or REACH for general consumer use
Labeling: Labeling requirements focus on purity, presence in food products, and warnings about overconsumption, especially in supplement form
