Nature: Botanical extract derived from the dried leaves of Camellia sinensis
Physical Form: Fine brown powder or viscous dark liquid
Inhalation: Remove from exposure. Move to fresh air. Seek medical attention for persistent symptoms such as coughing or throat irritation.
Skin Contact: Remove contaminated clothing. Wash skin with plenty of water and mild soap. Consult a doctor if irritation, redness or rash persists.
Eye Contact: Rinse cautiously with water for at least 10 minutes. Remove contact lenses. Continue rinsing. Medical attention recommended if discomfort continues.
Ingestion: Rinse mouth with water. Do not induce vomiting. Give water or milk to drink only if conscious. Get medical attention if feeling unwell or experiencing abdominal pain.
Most Important Symptoms: Mild irritation of eyes, skin, or airways. Overconsumption may cause gastrointestinal effects.
Suitable Extinguishing Media: Use water spray, foam, dry chemical, or carbon dioxide.
Special Hazards: Combustible as organic material. Dust may form explosive mixtures in air under high concentrations.
Protective Equipment: Wear self-contained breathing apparatus and protective clothing to avoid inhaling smoke and fumes.
Hazardous Combustion Products: May release carbon monoxide, carbon dioxide, and minor nitrogen oxides under fire conditions.
Advice for Firefighters: Keep containers cool with water spray. Avoid inhaling vapors. Prevent the release of contaminated runoff to sewers.
Personal Precautions: Use adequate ventilation. Avoid dust formation and contact with eyes and skin. Wear protective gloves and a dust mask.
Environmental Precautions: Prevent entry into drains, surface water, or soil. Collect spill to prevent environmental release.
Cleanup Methods: Scoop up spilled material and place in appropriate waste container. Wipe residue with damp cloth or wash area with water.
Disposal: Follow local regulations for waste disposal. Non-hazardous solid waste category.
Precautions for Safe Handling: Avoid contact with skin, eyes, and clothing. Avoid inhalation of dust or vapor. Ensure good ventilation or local exhaust at workplace.
Safe Storage Conditions: Store in tightly closed containers. Keep in cool, dry, and well-ventilated place, away from strong oxidizers, acids, and sources of ignition.
Special Storage Requirements: Protect from moisture, heat, and direct sunlight to maintain potency and prevent clumping.
Occupational Exposure Limits: No specific limits set for black tea extract. Keep dust below general nuisance thresholds (e.g., 10 mg/m³, 8 hr TWA for total dust).
Engineering Controls: Use local exhaust or process enclosure to reduce airborne dust.
Personal Protective Equipment: Wear safety goggles, gloves, lab coat or apron, and dust mask (N95 or similar).
Hygiene Measures: Wash hands thoroughly after handling. Remove contaminated clothing and wash before reuse. Do not eat, drink, or smoke in the work area.
Appearance: Brown to dark brown fine powder; liquid version is dark brown and mobile
Odor: Characteristic tea aroma
pH: 4.0 – 7.0 (1% solution in water)
Melting Point/Range: Not applicable for mixture; main components decompose above 120°C
Boiling Point/Range: Not determined (decomposes before boiling)
Flash Point: Not flammable under normal circumstances
Solubility: Readily soluble in water. Slightly soluble in alcohol.
Density: Approximately 0.35 – 0.6 g/cm³ (powder)
Auto-ignition Temperature: Not available, expected >220°C (organic solids)
Partition Coefficient (n-octanol/water): Not measured for mixture
Other Properties: Stable under recommended storage conditions. Bulk density may vary due to particle size.
Stability: Stable under normal storage conditions. Sensitive to air, humidity, and light.
Reactivity: Not reactive with most common materials.
Incompatible Materials: Strong oxidizing agents, acids, bases.
Hazardous Decomposition Products: Carbon dioxide, carbon monoxide, and other organic vapors possible upon combustion.
Polymerization: Will not occur.
Acute Toxicity: Data on acute oral toxicity indicate LD50 (rat) estimated above 5000 mg/kg. Low acute toxicity.
Skin Corrosion/Irritation: Prolonged skin contact can cause mild irritation on sensitive individuals.
Eye Damage/Irritation: Causes minor, reversible discomfort or redness.
Respiratory Effects: Inhalation of dust may produce minor irritation or coughing.
Chronic Effects: No evidence of mutagenicity, carcinogenicity, teratogenicity shown in animal studies for tea components.
Other Effects: May cause mild gastrointestinal disturbance if ingested in large amounts due to caffeine and tannins.
Ecotoxicity: Not classified as dangerous for the environment. Rapidly biodegradable. Components found in tea are plant-derived and break down naturally.
Aquatic Toxicity: No significant effects at expected environmental concentrations. High levels may lead to nutrient enrichment.
Persistence and Degradability: Readily biodegradable through standard wastewater treatment processes.
Bioaccumulation Potential: Expected to be low. Polyphenols and caffeine do not persist or bioaccumulate in the environment.
Mobility in Soil: Water-soluble components may leach into soil but degrade rapidly.
Disposal Methods: Dispose in accordance with local, regional, and national regulations for non-hazardous waste. No special handling required.
Contaminated Packaging: Rinse containers with water before recycling or disposal.
