Name: Methyl Myristate
Chemical Formula: C15H30O2
Synonyms: Myristic acid methyl ester
Appearance: Clear, colorless liquid
Odor: Mild, fatty scent
Common Uses: Personal care products, lubricants, some food applications; also shows up in research settings
CAS Number: 124-10-7
Physical Form: Liquid at room temperature
Most Encountered State: Bottled, ready-made for industry and lab use
Main Health Risks: Prolonged or repeated skin contact may cause mild irritation or dryness; can irritate eyes if splashed
Inhalation Hazards: Vapors can cause mild respiratory discomfort in one with sensitivities, especially with poor ventilation
Flammability: Burns with a low to moderate flash point, which raises concerns for storage and transport
Environmental Risk: Not acutely toxic to aquatic life, but still worth limiting entry into waterways
Visual Warning: Usually no strong colors or labels unless mixed with other substances, so awareness matters
Chemical Name: Methyl Myristate
Concentration: Typically 95% or above in lab reagents; varies in commercial or blended products
Impurities: Small traces of related esters or alcohols if not highly refined
Reactivity: Stable under most ordinary conditions, but reacts with strong oxidizers
Skin Contact: Remove contaminated clothing, rinse with soap and plenty of water; seek medical advice if skin reaction happens
Eye Contact: Flush eyes gently with water for several minutes; remove contact lenses for a thorough rinse
Inhalation: Move to fresh air, monitor for breathing difficulty; rest if feeling dizzy or lightheaded
Swallowing: Rinse mouth, drink water if conscious; seek professional help, as with any chemical ingestion
Suitable Extinguishing Agents: Use dry chemical, foam, or CO2 for small fires; water fog may help prevent re-ignition
Hazards in Fire: Emits irritating fumes if burned; keep distance and avoid breathing vapors
Protective Actions: Wear self-contained breathing apparatus and full protective gear
Firefighting Advice: Keep containers cool with water spray if exposed to heat or flame
Explosion Risk: Closed containers may rupture when exposed to heat
Small Spills: Absorb with inert material, place in chemical waste container
Large Spills: Dike far ahead of liquid for recovery or disposal; prevent run-off to open drains
Personal Safety: Use gloves, eye protection, and adequate ventilation
Clean-Up: Wash contaminated area with water and mild detergent after picking up the bulk material
Handling Precautions: Limit skin and eye contact; keep containers tightly closed; avoid breathing vapors
Storage Needs: Store in a cool, dry space; keep away from heat, sparks, and open flame
Container Requirements: Use only chemical-resistant containers
Incompatibilities: Avoid storing with strong oxidizers
Engineering Controls: Work under local exhaust or general ventilation; fume hoods help for lab-scale work
Personal Protective Equipment: Wear protective gloves, safety glasses, and chemical-resistant apron where splash is possible
Respiratory Support: Dust mask or organic vapor respirator in case of high vapor concentrations, though typical handling doesn’t require it
Hygiene Measures: Wash hands after use, avoid eating or drinking in work areas
State: Liquid at room temperature
Color: Clear to pale yellow
Odor: Mild, fatty
Boiling Point: Around 276°C
Melting Point: About 18–22°C
Flash Point: About 124°C (closed cup)
Solubility: Insoluble in water but mixes easily with organic solvents
Vapor Pressure: Low, so evaporation rate is slow
Density: Close to 0.86–0.87 g/cm³ at 25°C
Chemical Stability: Remains stable under ordinary conditions
Dangerous Reactions: May react with strong oxidizers, producing heat or fumes
Hazardous Decomposition Products: In fire, can emit carbon monoxide, carbon dioxide, small organic compounds
Conditions to Avoid: High temperatures, open flames, and incompatible chemicals
Acute Toxicity: Low oral and dermal toxicity in mammals, based on similar esters
Skin Effects: Likely mild, limited to possible dryness or irritation after long exposure
Eye Effects: Brief exposure can cause stinging or redness
Chronic Exposure: No evidence of long-term toxicity or carcinogenicity using normal industry concentrations
Inhalation Effects: Generally low risk due to very low volatility
Environmental Fate: Slowly breaks down via natural biodegradation
Aquatic Toxicity: Not highly toxic to aquatic life; breaks down into simple compounds
Bioaccumulation: Low potential since it doesn’t persist or build up in tissue
Best Practice: Limit release to waterways, collect for proper disposal rather than washing down drains
Waste Methods: Collect in sealed, labeled containers and send to chemical disposal contractor
Contaminated Packaging: Rinse, triple-wash, and dispose according to local regulations
Environmental Steps: Avoid releasing into the environment; do not pour into public sewers or water courses
Incineration: Permitted only in facilities equipped for chemical waste
Road and Rail: Transport as a chemical liquid, not classified as hazardous under most transit rules
Air and Sea: Pack properly to prevent leaks; check with carrier for any specific restrictions
Packaging Advice: Seal tightly, keep containers upright; add absorbent around glass bottles during transport, especially by air
Workplace Safety: Follow standard chemical hygiene guidelines; not subject to stringent restrictions, but treat with the care every chemical deserves
Environmental Law: Not listed as a hazardous pollutant or priority substance in most jurisdictions, but always check regional updates
Labeling: Include routine hazard statements on containers; comply with safety pictogram standards where applicable
Permits: No permits required for typical research or manufacturing use, but bulk storage or disposal may involve local oversight
