Classification: Not classified as hazardous under current GHS criteria for pure vitamin E alcohol
Label Elements: No pictogram, no signal word
Primary Routes of Exposure: Inhalation, eye and skin contact, ingestion
Hazards: Eye irritation with direct exposure; mild skin irritation possible; inhalation of dust may irritate mucous membranes; ingestion of high doses can cause nausea, diarrhea, or cramps
Environmental Concerns: Not hazardous to aquatic life or the ozone layer at normal concentrations
Chemical Name: DL-Alpha-Tocopherol
Concentration: ≥99%
Impurities/Fillers: None intentionally present for acetate-free type
Other Components: None anticipated for unadulterated powder or oil
Inhalation: Move person to fresh air; seek medical attention for symptoms like coughing, shortness of breath, or breathing irritation
Skin Contact: Wash area thoroughly with soap and water; remove contaminated clothing if present; monitor for irritation
Eye Contact: Irrigate eyes gently with plenty of water for at least 15 minutes, lifting eyelids occasionally; medical help if irritation persists
Ingestion: Rinse mouth; drink water to dilute, do not induce vomiting; take medical advice if large quantity swallowed or symptoms develop
Most Important Symptoms/Effects: Mild gastrointestinal upset, skin or eye irritation with high exposure
Protection for First Responders: Gloves and eye protection recommended in all suspected exposures
Suitable Extinguishing Media: Water spray, dry chemical, foam, or CO2 can suppress flames
Unsuitable Media: High-pressure water jets may scatter material
Hazards: Burns as organic material, emitting acrid fumes, carbon oxides if combustion is incomplete
Protective Equipment for Firefighters: Self-contained breathing apparatus and full protective gear
Special Procedures: Contain runoff; use standard firefighting techniques for combustible solids or viscous liquids
Personal Precautions: Wear gloves, lab coat, goggles to avoid contact; ventilate area
Spill Cleanup: Collect solid or viscous material with non-sparking tools and transfer to appropriate waste container; wash spill site after removal
Prevention of Environmental Impact: Avoid discharge into drains or surface waters
Methods for Cleaning Up: Sweep or scoop up; use absorbent material for oils; place in containers for disposal
Handling: Avoid inhaling dust and direct contact with eyes or skin; use in well-ventilated zone
Storage Conditions: Keep tightly sealed in cool, dry, dark environment, away from high heat, open flames, or oxidizing chemicals
Special Precautions: Store away from sources of ignition and incompatible substances; keep containers upright and clearly labeled
Bulk Storage: Use inert gas overlay for larger volumes to prevent oxidation
Specific End Uses: Only for industrial, laboratory, or authorized food and feed applications as defined by local regulation
Occupational Exposure Limits: No official thresholds for pure tocopherol; use general nuisance dust limits (e.g., ACGIH TLV for particulates not otherwise classified 10 mg/m³ inhalable, 3 mg/m³ respirable)
Engineering Controls: Handle in fume hood or use extraction ventilation for dusty operations
Personal Protection—Respiratory: Dust mask or particulate respirator when airborne dust is possible
Personal Protection—Skin: Nitrile or latex gloves
Personal Protection—Eyes: Protective goggles or safety glasses
Personal Protection—General: Avoid eating or drinking near material, wash hands thoroughly after handling
Appearance: Clear, viscous oil or pale yellow powder, acetate-free version
Odor: Mild, fatty
Odor Threshold: Not determined
pH: Not applicable (non-water soluble oil)
Melting Point: 2–3°C (oil)
Boiling Point: >200°C
Flash Point: >200°C (closed cup)
Evaporation Rate: Not volatile
Flammability: Combustible, can sustain fire in direct flame
Vapor Pressure: Negligible at ambient temperature
Vapor Density: No data
Relative Density: Approx. 0.95–0.97 (oil)
Solubility: Practically insoluble in water; soluble in organic solvents like ethanol, chloroform, fats
Partition Coefficient (log Kow): High (lipophilic)
Auto-Ignition Temperature: Data unavailable/specifically not tested
Decomposition Temperature: Above 250°C
Viscosity: High (for oil)
Chemical Stability: Stable under recommended storage conditions; slowly degrades with prolonged exposure to air, heat, or light
Possibility of Hazardous Reactions: Does not polymerize; can oxidize if not protected from light and oxygen
Conditions to Avoid: High heat, open flames, direct sunlight, strong light exposure
Incompatible Materials: Strong oxidizers such as peroxides, chlorine, or concentrated nitric acid
Hazardous Decomposition Products: Oxides of carbon (CO, CO2), acrid smoke on burning
Acute Toxicity: Low oral toxicity in humans; no acute dermal or inhalation toxicity documented at regular workplace concentrations
Skin Corrosion/Irritation: Unlikely to cause skin damage; may cause minor irritation in sensitive individuals
Eye Damage/Irritation: Irritation possible with direct exposure
Sensitization: No known sensitizing effects
Germ Cell Mutagenicity: No evidence in animal or cellular studies
Carcinogenicity: Not considered carcinogenic by IARC, NTP, or OSHA
Reproductive Toxicity: Not expected toxic to reproduction
Specific Target Organ Toxicity—Single Exposure: No target organ effects identified
Long-Term Effects: No significant adverse effects observed with normal exposure; mega-doses by mouth may cause GI upset
Symptoms of Overexposure: Large dose ingestion may result in fatigue, headache, mild digestive symptoms
Ecotoxicity: Not hazardous to aquatic organisms at normal levels; readily biodegradable
Persistence and Degradability: Decomposes by routine natural processes; rapidly degraded by microbial activity in soil and water
Bioaccumulative Potential: Low bioaccumulation risk due to metabolism and breakdown in biological systems
Mobility in Soil: Low mobility, binds to organic matter
Other Adverse Effects: Active ingredient not considered environmentally toxic at realistic concentrations
Waste Disposal: Manage as non-hazardous chemical waste, follow local regulations; incineration preferred for oils, landfill for dry solids
Container Disposal: Empty containers should be rinsed and recycled or disposed of in line with local legal requirements
