Chemical Name: Eicosapentaenoic acid ethyl ester Synonyms: EPA-EE, ethyl (5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenoate Common Uses: Active in certain pharmaceuticals for heart and blood health, research chemical in laboratories, food supplement ingredient in select regulated products Appearance: Pale-yellow, oily liquid, odor resembling fish oil Molecular Formula: C22H34O2 Molecular Weight: About 330.5 g/mol Solubility in Water: Nearly insoluble, mixes better with organic solvents Typical Impurities: Minor related fatty acid ethyl esters, saturated and mono-unsaturated fats from oil source
GHS Classification: Usually not classified as hazardous under normal laboratory conditions, but acts as an irritant at higher concentrations Routes of Exposure: Mainly skin contact, accidental ingestion, inhalation unlikely but possible as aerosol Key Risks: Minor skin or eye irritation, gastrointestinal discomfort on ingestion in large amounts, persistent odors on exposure Pictograms: Not generally required, but best practices lean on handling like organic oils Symptoms of Exposure: Redness on skin, burning eyes, nausea if consumed excessively, greasy residue leading to slipping hazards
Main Ingredient: Eicosapentaenoic acid ethyl ester Purity (Research/Pharma Grade): Often exceeds 90%, trace amounts of docosahexaenoic acid ethyl ester, small residual solvents from production Common Additives: Mixed tocopherols as antioxidants, possibly traces of carrier oils or ethanol Contaminants: Trace pesticides or PCBs in fish-derived products, regularly screened out in high-quality preparations
Skin Contact: Wash off with soap and water, remove contaminated clothing, persistent feel of oiliness may remain Eye Contact: Rinse eyes thoroughly with water, blink repeatedly, see medical provider if irritation lingers Inhalation: Move to fresh air if aerosol or vapor inhaled by accident, rare given low volatility Ingestion: Rinse mouth, drink water, skip vomiting unless instructed by medical professionals, large intakes could lead to digestive upset Medical Attention: Seek help for persistent irritation, difficulty breathing, severe digestive reactions
Suitable Extinguishing Media: Foam, carbon dioxide, dry chemical for small fires, use water spray to cool surfaces Special Hazards: Combustion produces carbon monoxide, carbon dioxide, possibly acrid smoke Firefighting Equipment: Self-contained breathing apparatus, full protective gear for responders Advice for Responders: Isolate area, keep oil from entering drains, slippery spills near fire risk area increase injury risk
Personal Precautions: Wear gloves, wipe up spills immediately to avoid slipping, open windows or increase airflow Environmental Precautions: Keep oil out of waterways and soil, minimize runoff Cleanup Method: Absorb with inert material like sand or vermiculite, scoop into secure container, wash surface thoroughly Disposal: Collect all residues and contaminated cleanup tools for proper disposal following local chemical waste rules
Personal Handling: Avoid prolonged contact with skin, do not ingest, wear gloves if spillage likely Safe Storage: Store in cool, dry, ventilated place away from sunlight, heat sources, oxidizing agents Incompatible Storage Materials: Avoid storing near strong acids, alkalis, and oxidizers Container Advice: Keep container tightly sealed to prevent oxidation, ideally use amber glass or appropriate plastic
Engineering Controls: Work under fume hood if handling large volumes or heating the material Personal Protective Equipment: Gloves resistant to oils, safety goggles for splash risk, lab coat Exposure Limits: No established occupational exposure limits, but keeping airborne mist low stops inhalation issues Hygiene Measures: Wash hands after handling, clean protective equipment regularly, avoid eating, drinking, or smoking in work area
Appearance: Light yellow, oily liquid Odor: Faint fish-oil scent Boiling Point: Above 430°C (at 760 mm Hg, decomposes before boiling) Melting Point: Below room temperature, remains liquid under normal conditions Flash Point: Estimated above 200°C Vapor Pressure: Very low Solubility: Negligible in water, mixes well with most organic solvents Density: Near 0.9 g/cm³ Viscosity: Oily, similar to common vegetable oils
Stability: Stable under normal conditions with minimal light and air exposure Decomposition: Can break down with prolonged heat, forms aldehydes and acids Incompatible Materials: Strong oxidizing agents, acids, bases accelerate spoilage and breakdown Hazardous Reactions: Tends to form peroxides during long-term storage in open air, increasing rancidity
Acute Toxicity: Low when administered orally to laboratory animals, high doses in humans bring mild gastrointestinal discomfort Chronic Exposure: Unknown at non-pharmaceutical concentrations, fish oil studies suggest rare allergic responses Irritation: Prolonged contact may irritate skin and eyes Carcinogenicity: No evidence linking eicosapentaenoic acid ethyl ester itself to cancer Sensitization: Allergic responses rare, most often traced to impurities rather than the ester itself Special Populations: Pregnant women, children, and individuals with fish allergies should consult healthcare providers
Aquatic Toxicity: Low risk to aquatic life in small accidental spills, larger amounts promote oxygen demand as microorganisms break down the oil Persistence and Degradability: Readily biodegradable, similar to natural fatty acids Bioaccumulation: Unlikely, breaks down through metabolic processes in most living systems Soil Impact: May lead to oily patches that suffocate roots or soil-life if spilled in volume Precautions: Avoid direct release into waterways or soils, treat as oil waste under most environmental protection rules
Waste Disposal: Collect excess material in tightly closed container, send to licensed chemical waste processor Contaminated Packaging: Triple rinse containers, treat rinsate as chemical waste Best Practices: Never pour down drains or municipal garbage, prevent bulk buildup in landfill
Shipping Status: Not classified as dangerous for transport by road, sea, or air in most regions Packaging Considerations: Tight, sealed containers prevent leaks, cushioned packing for glass bottles Labeling: Standard chemical identification, precautionary marking for oil spills recommended Precautions in Transport: Keep away from reactive chemicals, avoid high temperatures, keep upright to limit leaks
Status Under Chemical Regulation: Not listed as hazardous under European REACH, US TSCA, or equivalent regulations for research and pharmaceutical grades Food and Drug Laws: Reviewed by WHO, FDA, EMA for medical use in fish oil derivatives; always check current country-specific food and supplement status Worker Safety Laws: Standard for handling oils and solvents apply, follow local chemical hygiene plans Environmental Rules: Handle and dispose as regulated oily organic chemical, not as general waste, rules vary depending on jurisdiction
