Chemical Name: Bio-N-Hexyl Methacrylate
Concentration: ≥98%
Impurities: ≤2% (including methyl methacrylate traces, inhibitors like MEHQ)
Stabilizer: methyl ether hydroquinone (MEHQ), up to 200 ppm
Inhalation: Remove individual to fresh air. Seek medical advice if symptoms (headache, dizziness, irritation) persist.
Skin Contact: Remove contaminated clothing. Wash exposed skin thoroughly with soap and water. Seek medical attention for persistent redness or blistering.
Eye Contact: Rinse the eyes gently but thoroughly with tempered water for at least 15 minutes. Seek immediate medical care if irritation remains or vision is blurred.
Ingestion: Rinse mouth with water. Do not induce vomiting. Seek medical attention. Keep the person calm and avoid giving anything by mouth to an unconscious person.
Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide, water spray for cooling only. Do not use direct water stream.
Specific Hazards: Vapors can form explosive mixtures with air. Fire can produce toxic fumes—carbon monoxide, carbon dioxide.
Protective Equipment: Full firefighting gear, self-contained breathing apparatus recommended. Approach upwind.
Special Firefighting Instructions: Remove containers from hazard area if safe. Cool containers with water to prevent pressure build-up.
Personal Precautions: Evacuate non-essential personnel. Avoid breathing vapor. Use gloves, goggles, chemical-resistant apron.
Environmental Precautions: Prevent material from entering drains, sewers, waterways. Use barriers or absorbents as required.
Cleanup Methods: Absorb spills with inert material like sand or earth. Do not return the spilled material to original container. Collect in a sealable container for disposal in accordance with local regulations. Ventilate the area and wash the site with water after removal.
Handling: Handle in well-ventilated place. Avoid exposure to heat, sparks, flames. Do not breathe vapors or allow contact with skin and eyes. Use only with grounded, spark-proof equipment.
Storage: Store in tightly closed, properly labeled containers, out of direct sunlight and away from heat sources. Keep storage area cool, dry, with exhaust ventilation. Use temperature control (store at 2-8°C to prevent polymerization). Add stabilizer (MEHQ) as recommended. Keep clear of oxidizing agents and acids. Avoid storage near food or animal feed.
Occupational Exposure Limit: No specific OSHA or ACGIH TLV established for Bio-N-Hexyl Methacrylate; general limit for methacrylate monomers: 50 ppm TWA recommended
Engineering Controls: Local exhaust ventilation or process enclosure to control vapor levels.
Respiratory Protection: Use organic vapor respirators in poorly ventilated zones.
Skin Protection: Chemical-resistant gloves (nitrile, neoprene), long sleeves, aprons
Eye Protection: Safety goggles or face shield
Hygiene: Avoid eating, drinking, or smoking while handling. Wash hands and face after use.

Materials to Avoid: Strong acids, alkalis, oxidizers, peroxides, azo compounds.
Hazardous Decomposition Products: Methacrylic acid, formaldehyde, carbon dioxide, carbon monoxide.
Polymerization Risk: Strongly exothermic, may result in container rupture.
Inhibitor Content: Contains MEHQ to slow unwanted polymerization.
Routes of Exposure: Inhalation, skin, eye contact, ingestion
Acute Toxicity: LD50 (oral, rat): >5000 mg/kg; LD50 (dermal, rabbit): >5000 mg/kg
Skin Irritation: Mild to moderate irritant; repeated or prolonged contact causes redness, dryness, or cracking
Eye Irritation: Irritating — risk of redness, watering, pain
Respiratory Issues: Inhalation of high concentrations: dizziness, headache, respiratory tract irritation
Sensitization: Cases of skin sensitization have been described in occupational settings
Chronic Effects: Not classified as carcinogenic; long-term effects based on animal testing are low. Some reports of liver or kidney effects from chronic high-exposure doses
Aquatic Toxicity: Moderately toxic to aquatic life: LC50 (fish, 96hr): ~10 mg/L
Persistence and Degradability: Breaks down slowly in water, faster in soil or air. Material not readily biodegradable.
Bioaccumulation: Low potential for bioaccumulation (log Ko/w ≈ 4.0).
Mobility: May leach into soil, lightly mobile in water, tends to evaporate.
Other Hazards: Avoid discharge to sewer or open water. Product breaks down to organic acids on exposure; environmental impact increases with large spills
Waste Disposal: Hand over material and contaminated packaging to a licensed waste disposal company. Incineration recommended for liquid waste.
Unclean Packaging: Empty containers can contain trace residues; do not reuse drums or bottles. Dispose of according to local regulations.
Regulations: Follow applicable federal, state, and local rules regarding hazardous waste. Avoid discharge into environment.
