Chemical Name: Linolenic Acid Methyl Ester Isomer Mix
Synonyms: Methyl esters of linolenic acids, C18:3 fatty acid methyl esters
Common Use: Component in biodiesel production, lubricants, and specialty chemical applications
Appearance: Clear to pale yellow liquid. Distinctive fatty odor.
Odor: Faint, fatty
Boiling Point: Generally lies above 200°C, characteristic of long-chain esters
Classification: Not classified as acutely toxic, but causes irritation with skin or eye contact
Physical Hazards: Flammable liquid
Routes of Exposure: Inhalation of mist, skin contact, ingestion
Common Symptoms: Redness, irritation, possible nausea with ingestion
Chronic Risks: Prolonged or repeated contact might dry or crack skin; no clear evidence for carcinogenicity or acute organ toxicity reported in reputable studies
Active Components: Methyl esters of α-linolenic acid, γ-linolenic acid, and other geometric or positional isomers
Typical Range of Main Component: Varied blend, but most content above 85 percent methyl esters
Impurities: Minor presence of residual methanol, potential traces of non-reacted fatty acids
Inhalation: Move affected individual to fresh air, support breathing if needed
Eye Contact: Rinse gently with moderate water flow for several minutes, avoid rubbing
Skin Contact: Wash with soap and water, remove any contaminated clothing
Ingestion: Rinse mouth, do not induce vomiting unless directed by medical staff; seek medical attention if feeling unwell
General Note: Provide supportive care as symptoms develop, seek further evaluation for persistent symptoms
Suitable Extinguishing Media: Use foam, carbon dioxide, or dry chemical extinguishers
Special Hazards: Vapors can form explosive mixtures with air at elevated temperatures
Protective Equipment: Wear self-contained breathing apparatus and full protective gear
Combustion Byproducts: Carbon oxides, potential acrolein formation when overheated or combusted
Personal Protection: Avoid inhaling vapors, ventilate area, use gloves and eye protection
Containment: Absorb spill with inert materials like sand or earth
Cleanup: Collect absorbed material for proper disposal, wash area thoroughly to remove residues
Environmental Consideration: Prevent entry into drains or waterways, alert authorities if significant environmental release occurs
Handling: Use proper ventilation, avoid ignition sources, ground containers during transfer
Storage: Store in tight, closed containers in a cool, dry, well-ventilated place away from heat, sparks, and open flames
Incompatible Materials: Strong oxidizing agents
Additional Precautions: Avoid static electricity buildup, do not eat, drink, or smoke during use
Engineering Controls: Local exhaust ventilation recommended in confined areas
Personal Protective Equipment: Wear chemical-resistant gloves and safety goggles
Hygiene Measures: Wash hands after handling, remove contaminated clothing promptly
Occupational Exposure Limits: No strict regulatory limit, but minimize exposure as a best practice, especially where aerosols or mists can form
Physical State: Liquid at ambient conditions
Color: Typically pale yellow
Odor: Mild, fatty
Boiling Point: Above 200°C
Melting Point: Below 0°C
Molecular Weight: Around 292 g/mol (dependent on isomer)
Flash Point: Estimated above 100°C (closed cup)
Solubility: Insoluble in water, soluble in most organic solvents
Vapor Pressure: Very low at room temperature
Chemical Stability: Stable under recommended storage conditions
Conditions to Avoid: Heat, open flame, strong oxidizers
Hazardous Decomposition: Combustion can generate carbon monoxide, carbon dioxide, and traces of acrolein
Polymerization: Not anticipated during normal use
Acute Toxicity: Low toxicity if ingested in small amounts, but can irritate mucous membranes in larger quantities
Dermal Exposure: Repeated exposure may cause drying or irritation
Eye Contact: Causes redness and discomfort
Carcinogenicity: No classification as carcinogenic from global agencies
Long-term Risks: No evidence to suggest chronic health issues from routine, careful use
Environmental Behavior: Readily biodegradable, breaks down by natural microbial action
Toxicity to Aquatic Life: No significant toxic effect reported at environmental concentrations
Mobility: Limited water solubility, persistent oily residue may affect soil or surface water if spilled in large amounts
Bioaccumulation: Tends not to bioaccumulate due to natural breakdown processes
Preferred Disposal Methods: Incinerate in approved facility or dispose along with oily organic waste streams
Disposal of Containers: Triple rinse and recycle if possible, or dispose in accordance with local regulations
Special Precautions: Do not discharge to sewer or natural waters in bulk
Proper Shipping Name: Methyl esters, not otherwise specified
Hazard Class: Considered flammable liquids for transport
Packing Group: Commonly Group III for low hazard
Additional Requirements: Protect from high heat, keep containers secure during transport
Relevant Regulations: Subject to chemical registration systems such as REACH in Europe, TSCA in the United States
Labelling Requirements: Flammable symbol may be necessary on bulk packaging
Regulatory Status: Not considered highly hazardous or restricted, but safety precautions and proper documentation remain standard practice
