Emergency Phone: Listed on shipping documents per regulatory requirements
Hazard Classification: Non-flammable, not classified as hazardous under OSHA GHS
Routes of Exposure: Inhalation of powdered form, skin contact, ingestion
Potential Health Effects: May cause mild irritation to skin and eyes, no severe acute toxicity
Chronic Effects: High doses can impact liver function, as reported in medical literature
Label Elements: No pictogram required; safety phrases recommended for dust control
Target Organs: Liver after ingestion in excessive quantities
Environmental Impact: Low environmental hazard
Main Components: Epigallocatechin gallate (EGCG), epicatechin gallate (ECG), epicatechin (EC), epigallocatechin (EGC)
Concentration (Range): Natural extract, with polyphenols accounting for 80% or more
Additives: Often blended with maltodextrin for improved flow, occasionally silica as anti-caking agent
Impurities: Trace natural plant components such as caffeine, theanine, residual moisture
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes; seek medical advice if irritation persists
Skin Contact: Wash area thoroughly with soap and water; remove contaminated clothing
Inhalation: Move to fresh air and observe for symptoms; seek medical attention for respiratory discomfort
Ingestion: Rinse mouth, drink water, do not induce vomiting; obtain medical attention in case of discomfort
Extinguishing Media: Use water spray, CO2, dry chemical powder, or foam
Specific Hazards: Polyphenols are organic powder; can produce combustion gases like CO, CO2 in case of fire
Protective Equipment: Use self-contained breathing apparatus and full protective clothing
Explosion Risk: Fine dust may create risk of dust explosion if suspended in air and exposed to ignition
Fire-Fighting Procedures: Remove containers from fire zone if safe; cool exposed containers with water spray
Personal Precautions: Avoid breathing dust, use local exhaust ventilation, wear dust mask
Environmental Precautions: Prevent powder runoff to water courses; avoid large spills into drains or soil
Clean-up Methods: Sweep up using methods that avoid dust generation, place in suitable container for disposal
Spill Response: Provide adequate ventilation, clean spill area with water after removal of product residues
Handling: Minimize dust formation, use with adequate ventilation, avoid contact with eyes and prolonged skin exposure
Hygiene Practices: Wash hands and exposed skin after handling, do not eat, drink, or smoke in work area
Storage Conditions: Keep container tightly closed, store in a cool, dry, well-ventilated area
Sensitivity: Protect from exposure to moisture, direct sunlight, elevated temperature
Incompatibilities: Store away from strong oxidizers and acids
Occupational Exposure Limits: None established for tea polyphenols; general dust exposure recommendations apply (ACGIH TLV for nuisance dust: 10 mg/m³)
Engineering Controls: Use local exhaust, process enclosure, general ventilation
Personal Protection: Safety goggles, gloves, protective clothing, dust mask or N95 respirator
Environmental Controls: Prevent emissions to air, soil, water through process control and good housekeeping
Appearance: Fine, pale yellow to brownish powder; color varies with extract purity
Odor: Faint, astringent, characteristic of tea
pH: 4.0–7.5 (1% aqueous solution)
Melting Point: Decomposes above 220°C
Boiling Point: Not applicable (decomposes before boiling)
Solubility: Soluble in hot water, sparingly soluble in ethanol
Flash Point: Not flammable under normal conditions
Stability: Stable at room temperature, sensitive to light and heat
Other Properties: Hygroscopic, may clump in moist air
Chemical Stability: Stable under recommended storage conditions
Hazardous Reactions: May undergo oxidation in presence of air, especially in solution
Conditions to Avoid: High temperature, moisture, direct sunlight
Incompatible Materials: Strong oxidizers, acids, bases
Decomposition Products: Carbon oxides, trace phenolic compounds, tannins
Acute Toxicity: Oral LD50 (rat): >5000 mg/kg; considered non-toxic under normal use levels
Irritation: Slight irritation possible to eyes, mild skin irritation reported in sensitive individuals
Chronic Exposure: High, chronic consumption linked to liver impact in some reports; EFSA and FDA recommend limits for supplements
Allergenic Effects: No known allergenic proteins identified; caution for individuals with tea allergies
Carcinogenicity: Not listed by IARC, NTP, OSHA
Mutagenicity: No significant data indicating genetic hazard
Reproductive Effects: No adverse effects documented at regular consumption levels
Aquatic Toxicity: Low; biodegradable and not expected to accumulate significantly in water systems
Soil Mobility: Binds to soil, breaks down by microbial action
Persistence and Degradability: Readily biodegradable in the environment
Bioaccumulation Potential: Unlikely to bioaccumulate due to water solubility
Other Effects: High concentrations can cause localized water discoloration; no chronic effects documented
Waste Disposal: Dispose of in accordance with local, state, federal regulations
