Chemical Name: α-Tocopherol Other Names: Vitamin E, tocopherol Molecular Formula: C29H50O2 Molecular Weight: 430.71 g/mol Appearance: Slightly yellow to amber clear viscous liquid Odor: Mild, characteristic Major Use: Antioxidant in food, supplements, cosmetics Common Exposure: Production, finished products, handling in food processing, lab and retail settings Solubility: Insoluble in water, soluble in ethanol and oils
Main Risks: Skin irritation for sensitive individuals, eye irritation, possible respiratory irritation from vapors; overexposure at high intake levels can cause headache, fatigue, nausea GHS Labeling: Not classified as hazardous under US OSHA or EU CLP for most workplace uses Warning Symbols: Usually not required, but eye protection may be noted Routes of Entry: Skin contact, eye contact, inhalation if misted, ingestion Long-Term Concerns: Chronic overdose by ingestion linked to increased bleeding risk Signal Words: "Caution" in some contexts, especially in concentrated or industrial form
Main Ingredient: α-Tocopherol (over 90%) Impurities: Small amounts of tocopherols (beta, gamma, delta), trace solvents from extraction Additives: None unless diluted or in formulated products Allergens: Seldom reported, but purity and source should be noted Intended Purity: Food-grade or USP/EU pharmacopeia standard in many uses
Eye Contact: Rinse cautiously with water for several minutes; remove contacts if possible Skin Contact: Wash with soap and water; for irritation, seek medical advice Inhalation: Move to fresh air if discomfort from vapor or mist; seek help if symptoms persist Ingestion: Rinse mouth; usually not harmful in small amounts, but massive overdosing requires medical attention Unusual Reactions: Seek immediate care for allergic response or persistent symptoms
Ignition Risk: Combustible at high temperatures Suitable Extinguishers: CO2, dry chemical, foam Hazardous Combustion Products: Carbon monoxide, carbon dioxide, irritating fumes Special Gear for Firefighters: Standard turnout gear plus self-contained breathing apparatus Firefighting Challenges: Viscous oil can spread flames; potential for slippery floors in bulk storage
Spill Response: Absorb with earth, sand, or inert material to prevent slipping Personal Precautions: Wear gloves, goggles, clothing to avoid skin or eye contact Environmental Precaution: Block run-off to drains or waterways – high concentrations could harm aquatic life Cleanup Process: Sweep up residue, wash area with soap and water Waste Handling: Collect residue safely, dispose as oily waste or according to regulations
Handling Advice: Keep containers closed; transfer slowly to avoid spills and splashes Storage Conditions: Store at cool room temperatures, away from heat and light Container Material: Preferably amber glass or food-grade plastics Incompatible Agents: Strong oxidizers and acids can degrade tocopherol Bulk Practices: Use clean tools, avoid contamination with food or cosmetics Personal Measures: Wear gloves if sensitive or in frequent contact
Workplace Exposure Limits: None established for α-tocopherol due to low acute toxicity Personal Protective Equipment: Gloves for frequent or high-volume handling, goggles in case of splash, lab coat or apron Ventilation: Adequate air movement prevents vapor build-up, especially for heated or misted formulas Hygiene: Wash hands after use; avoid eating or drinking near material Special Precautions: In rare cases, sensitive individuals may show dermatitis or respiratory reaction
State: Liquid at standard temperature Color: Pale to deep yellow, nearly clear Odor: Faint, characteristic Viscosity: Thick, oily consistency Melting Point: About 2.5°C Boiling Point: Degrades before boiling at 200°C+ Flash Point: Around 199°C Solubility In Water: Nearly insoluble; remains in oil phase Solubility In Solvents: Soluble in ethanol, acetone, dichloromethane Partition Coefficient: High octanol-water partition reflects tendency to accumulate in fats
Chemical Stability: Stable under recommended storage conditions; sensitive to air, heat, light which speeds up decomposition Reactivity Hazards: Oxidation can produce breakdown products; strong acids or bases may trigger reactions Dangerous Decomposition Products: Carbon monoxide, carbon dioxide, peroxides if exposed to open flame or strong oxidizers Incompatible Materials: Strong acids, oxidizing compounds, alkali metals Shelf Life: Best used within 24 months of manufacture in unopened containers
Acute Toxicity: Extremely low toxicity for skin or inhalation exposure; oral LD50 in rats is over 2,000 mg/kg Chronic Exposure Risks: High-dose, long-term ingestion may impair blood clotting Irritation: In rare cases can cause mild skin or eye irritation Allergenicity: Few cases, normally related to contaminated or oxidized product Sensitization: Not reported in workplace studies Carcinogenicity: Not listed as a carcinogen by IARC, NTP, OSHA Reproductive Effects: No evidence of harm at dietary or supplement levels Mutagenicity: Not documented as a mutagen
Aquatic Toxicity: Low, but oil can coat fish gills or aquatic plants at large spills Persistence: Breakdown slows in the environment due to fat solubility Bioaccumulation: Possible in aquatic fat stores, but rapid natural degradation limits risk Mobility: Remains in soils and sediments instead of leaching to water tables Degradation: Natural bacteria and sunlight break down compound over time
Preferred Disposal: Treat oil as non-hazardous waste unless mixed or contaminated Recycling: Many facilities accept waste edible oils and bio-based chemicals for energy recovery Incineration: Permitted at regulated facilities Drain Disposal: Avoid disposal to drains; greasy residues clog pipes and harm aquatic habitats Landfill: Permissible if local rules allow, though landfilling liquids is widely discouraged Regulatory Note: Always check local or national rules before disposal of bulk product
Shipping Name: Usually shipped as “non-hazardous” UN Classification: Not regulated as dangerous goods for road, rail, sea, or air transport Packing Group: Does not require special packing unless bulk volumes Labeling: Product name and care instructions Special Problems: Viscosity may present challenges if container leaks or breaks
Inventory Status: Listed on all major chemical inventories, including US TSCA, EU REACH Food and Drug Approvals: Approved for food fortification and supplements in many regions Restrictions: Very high doses regulated in specific foods or supplements; workplace limits advised in rare cases Environmental Status: Not classed as hazardous to environment under typical uses Labeling Guidance: Pharmacy and food brands must follow supplement or OTC labeling laws; bulk product may carry workplace cautionary guidance
