Supplier Information: Manufacturer’s name, address, and emergency contact must appear on any shipping documentation
Emergency Phone: Refer to local supplier or internal emergency numbers
Classification: Not classified as hazardous under GHS regulation
GHS Label Elements: No symbol, no signal word
Potential Health Effects: Inhalation, ingestion, contact with skin or eyes can cause irritation for some people; not considered acutely toxic; symptoms such as respiratory discomfort or skin redness may appear after prolonged exposure
Environmental Effects: Minimal hazard, but avoid release to water systems
Precautionary Statements: Wash thoroughly after handling, avoid inhaling vapors, and prevent environmental contamination
Chemical Identity: Methyl cis-11-eicosenoate
Chemical Formula: C21H40O2
Molecular Weight: 324.54 g/mol
Content: >98% (by weight)
Impurities: Trace saturated methyl esters, residual solvents below regulatory thresholds
Inhalation: Move person to fresh air, support breathing if affected; seek medical attention if symptoms linger
Skin Contact: Remove contaminated clothing, wash skin with soap and plenty of water; consult a physician if skin irritation occurs
Eye Contact: Rinse eyes immediately with water for several minutes, lifting eyelids to ensure thorough irrigation; get medical attention for persistent discomfort
Ingestion: Rinse mouth, seek advice from a doctor if feeling unwell; do not induce vomiting unless instructed by a healthcare provider
Most Important Symptoms: May include mild irritation, redness, or coughing if inhaled in concentrated form
Suitable Extinguishing Media: Carbon dioxide, foam, dry chemical powder, water spray for larger fires
Unsuitable Media: Water jets can scatter and spread burning material
Specific Hazards: Combustion releases carbon oxides, irritant fumes; containers exposed to heat may rupture
Protective Equipment: Firefighters should wear self-contained breathing apparatus, protective clothing, and avoid inhaling fumes
Special Procedures: Evacuate area, fight fire from upwind, surround with non-flammable barriers to contain runoff
Personal Precautions: Ventilate area, avoid breathing vapors, use suitable personal protective equipment (PPE)
Environmental Precautions: Prevent entry to drains, surface water, and soil to limit environmental impact
Methods for Cleanup: Absorb spillage with inert materials like sand or vermiculite, place in closed containers for disposal, wash spill site once material is removed
Other Information: Notify authorities if large quantities enter waterways
Safe Handling Advice: Use in well-ventilated areas, keep away from open flames and static sources, avoid prolonged or repeated skin contact
Hygiene Practices: Wash hands after handling, remove contaminated clothing immediately
Storage Requirements: Store in tightly closed containers, in a cool, dry, well-ventilated area away from direct sunlight and incompatible substances such as strong oxidizers
Incompatible Materials: Strong acids, bases, oxidizing agents
Occupational Exposure Limits: No established limits for this chemical; use best industrial hygiene practices
Engineering Controls: Use process enclosures, exhaust ventilation, or other engineering controls to keep airborne levels low
Personal Protection: Chemical-resistant gloves (nitrile or PVC), safety goggles, protective clothing; if ventilation is inadequate, use approved respirators
Environmental Controls: Prevent chemical runoff during use and cleaning
Appearance: Clear to pale yellow liquid
Odor: Slight, oily
Boiling Point: About 160-180°C at reduced pressure
Melting Point: -14°C
Flash Point: >200°C (closed cup)
Solubility: Insoluble in water, soluble in organic solvents such as ethanol and hexane
Density: 0.85 – 0.88 g/cm³ at 20°C
Viscosity: Moderate, typical of long-chain fatty acid esters
Vapor Pressure: Negligible at room temperature
Chemical Stability: Stable under normal storage and handling conditions
Hazardous Reactions: No risk of polymerization, but reacts with strong oxidizers and acids
Hazardous Decomposition Products: Thermal breakdown can generate carbon monoxide, carbon dioxide, small amounts of acrolein and other irritant fumes
Conditions to Avoid: Exposure to strong heat sources, direct sunlight, sparks, and open flames
Incompatibility: Avoid mixing with strong oxidizers, peroxides, strong acids or alkalis
Acute Toxicity: Low oral and dermal toxicity based on analogous substances; not classified as acutely toxic by recognized agencies
Skin Corrosion/Irritation: May cause mild skin irritation with repeated or prolonged exposure
Eye Damage/Irritation: Contact can result in mild, reversible irritation
Respiratory Sensitization: Not a known respiratory sensitizer, but dust or mists may irritate airways
Carcinogenicity: No data indicate carcinogenic risk; not listed by IARC, NTP, or OSHA
Other Information: Chronic exposure data limited; no mutagenic or teratogenic effects observed in standard screenings
Ecotoxicity: Expected to have low toxicity for aquatic organisms; significant releases could disrupt surface films and oxygen transfer, which could harm aquatic life if present in large amounts
Persistence and Degradability: Biodegradable; fatty acid methyl esters naturally break down in the environment
Bioaccumulative Potential: Not anticipated to bioaccumulate appreciably due to metabolic breakdown
Mobility in Soil: Slight; binds to sediment and organic matter, minimal leaching expected
Other Adverse Effects: No information to suggest ozone depletion or dangerous global warming potential
Waste Treatment Methods: Recycle if possible; otherwise, dispose of in accordance with national and local regulations
Contaminated Packaging: Containers should be completely emptied, then sent for drum reconditioning or metal recycling
Recommendations: Do not allow product to enter drains, sewers, or natural watercourses; consult approved waste disposal companies for safe management
UN Number: Not assigned
UN Proper Shipping Name: Not classified as dangerous for transport
Transport Hazard Class: Not regulated
Packing Group: None assigned
Special Precautions: Avoid transporting with oxidizers or incompatible chemicals; ensure containers are sealed and secured to avoid leaks in transit
Marine Pollutant: No, based on current data
TSCA: Listed on the Toxic Substances Control Act inventory
DSL/NDSL (Canada): Listed/anticipated to be listed
REACH (EU): Meets requirements for registration or exemption for research or limited-volume production
Labeling (EU): Not classified as hazardous under CLP Regulation (EC) No. 1272/2008
SARA 313 (US): Does not contain chemicals at threshold reporting levels
Other Regulatory References: Not a controlled drug, precursor, or restricted chemical under primary US, EU, JP, or CA frameworks; always check the latest local, national, and international regulations prior to industrial use or international shipment
