Chemical Name: Triacetin
Other Names: Glyceryl triacetate
CAS Number: 102-76-1
Appearance: Clear, oily liquid, faint odor
Common Uses: Used as a plasticizer, food additive, solvent in pharmaceuticals, and flavoring agent
Main Hazards: Slight eye and skin irritation; minimal inhalation risks if vapor concentrations remain low
Routes of Exposure: Inhalation, skin and eye contact, ingestion
GHS Classification: Not classified as a hazardous substance by current global standards
Risk Phrases: May cause mild discomfort on contact; large quantities may present slight health risks with prolonged or repeated exposure
Signal Word: None required based on typical regulatory criteria
Main Ingredient: Triacetin (approx. 100%)
Impurities: Minimal, consisting mainly of trace byproducts from manufacturing
Nature: Simple ester derived from glycerol and acetic acid
Eye Contact: Rinse eyes gently with water for several minutes to remove liquid, seek medical attention if irritation persists
Skin Contact: Wash skin thoroughly with soap and water; remove contaminated clothing
Inhalation: Move person to fresh air; seek advice if symptoms develop
Ingestion: Rinse mouth with water; seek medical guidance if feeling unwell or after swallowing large quantities
Suitable Extinguishing Media: Use foam, dry chemical, or carbon dioxide
Specific Hazards: Combustion produces carbon dioxide, carbon monoxide, and possibly small amounts of acetic acid vapors; vapors may cause mild respiratory irritation
Protective Equipment: Use full protective clothing and self-contained breathing apparatus since smoke can irritate airways
Personal Precautions: Wear suitable gloves and goggles; avoid skin and eye contact
Spill Response: Absorb with sand or inert material; ventilate affected area
Clean-up Methods: Collect in containers for proper disposal; wash spill site after material pickup is complete
Handling: Use in a well-ventilated place; avoid breathing mist or vapors; wear protective equipment when handling in bulk
Storage: Store containers tightly closed in a cool, dry area protected from direct sunlight; keep away from strong oxidizing acids or bases, which can degrade the product
Ventilation: Ensure good ventilation during use
Personal Protection: Wear safety glasses and suitable gloves to minimize skin and eye contact
Respiratory Protection: Not usually necessary in open or ventilated areas; consider respiratory protection if exposure risk increases in confined spaces
Occupational Limits: No established exposure limits from OSHA, NIOSH, or ACGIH
State: Liquid at room temperature
Odor: Mild, slightly fruity or acetic
Melting Point: About -78 °C
Boiling Point: Around 258 °C
Solubility: Miscible with most organic solvents; slightly soluble in water
Density: Roughly 1.16 g/cm³
Viscosity: Moderate
Vapor Pressure: Low at room temperature
Chemical Stability: Stable under usual conditions of handling and storage
Reactivity: Reacts with strong acids, bases, and oxidizing agents
Hazardous Decomposition: Decomposes under fire conditions, producing acetic acid fumes, carbon monoxide, and carbon dioxide
Conditions to Avoid: Extended exposure to heat and open flames; contact with incompatible chemicals
Acute Toxicity: Very low toxicity for humans and animals under normal handling conditions
Skin and Eye Contact: May cause mild irritation, especially in sensitive individuals
Inhalation: Vapors unlikely to cause acute symptoms; excessive exposure could result in minor respiratory discomfort
Chronic Effects: No evidence suggests carcinogenicity or long-term health issues at typical exposure levels
Mobility: Triacetin shows some potential for water solubility but tends to partition to soils and sediments
Persistence: Readily biodegradable; breaks down through hydrolysis and microbial action
Toxicity to Aquatic Life: Low acute toxicity based on current studies; poses limited risk at normal discharge concentrations
Bioaccumulation: Unlikely to accumulate in living organisms, as metabolism tends to break it down
Product Disposal: Dispose in line with local chemical waste regulations; avoid release to drains, surface water, and soil
Container Disposal: Containers should be drained and rinsed before recycling or proper industrial disposal
Reusable Materials: Incinerate or recycle in specialized facilities whenever possible
Shipping Status: Not regulated as a hazardous material under most transport rules
Packaging: Use leak-proof containers; standard chemical transport precautions reduce spill risk
Special Precautions: Keep away from strong acids, bases, and oxidizers during transit to prevent unwanted reactions or leaks
Occupational Safety: Triacetin stays off most major hazard chemical lists due to low risk
Regulatory Listings: Approved for use as a food additive in many jurisdictions; listed as GRAS (Generally Recognized As Safe) in the United States
Environmental Safeguards: No special restrictions on release, though large-scale discharges should be controlled to prevent runoff
Worker Protection: Standard workplace safety rules for handling chemicals apply, including training and provision of safety data
