Other Ingredients: None deliberately present
Inhalation: Remove to fresh air, keep at rest in comfortable position for breathing, seek medical attention if symptoms develop
Skin Contact: Remove contaminated clothing, wash skin with soap and water for at least 15 minutes, do not use solvents or thinners, seek medical advice in case of irritation or allergic reaction
Eye Contact: Rinse eyes with water for several minutes, remove contact lenses if present and easy, continue rinsing, seek medical attention if irritation persists
Ingestion: Do not induce vomiting, rinse mouth, never give anything by mouth if victim is unconscious, seek immediate medical attention
Note to Physician: Treat symptomatically, monitor for hypersensitivity reactions
Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam, water spray (do not use water jet)
Specific Hazards: Vapors may form explosive mixtures with air, thermal decomposition releases acrid smoke, CO, CO2, possible acrylic monomers
Protective Equipment: Firefighters require self-contained breathing apparatus, full protective suit
Special Precautions: Remove containers from fire area if safe, cool closed containers with water spray, contain fire runoff
Flammability: Moderate, avoid ignition sources
Explosion Limits: Not established
Flash Point: Approx. 110°C (closed cup, check supplier’s latest data)
Personal Precautions: Evacuate area, ventilate affected space, wear gloves, goggles, and respiratory protection
Spill Clean-Up: Absorb with inert material (sand, earth, vermiculite), transfer to secure container for disposal, large spills require diking to contain run-off
Decontamination: Wash spill area with detergent and water after product removal
Environmental Precautions: Prevent entry into sewers, waterways, or soil, notify authorities if significant spill occurs
Sensitive Individuals: Allergic reactions possible from skin contact, limit exposure
Safe Handling: Use only in well-ventilated areas, avoid inhalation or direct contact, ground and bond containers for liquid transfer
Avoid: Static discharge, heat, open flames, unprotected light sources, oxidizing materials
Specific Procedures: Keep containers tightly closed when not in use, clean up splashes and spills promptly
Storage Conditions: Store between 5°C and 35°C, out of direct sunlight, away from food and incompatible materials
Packaging Materials: Use containers of corrosion-resistant, light-blocking materials with suitable venting
Incompatibilities: Strong acids, bases, oxidizers, free radical initiators
Shelf Life: Check manufacturer data, typically 12-18 months if unopened
Exposure Limits: No specific OSHA, ACGIH, or EU OEL established; minimize exposure based on irritation potential
Engineering Controls: Local exhaust ventilation, eye wash and safety showers in work area
Personal Protective Equipment:
Appearance: Clear, colorless to pale yellow liquid
Odor: Mild, ester-like
pH: Not applicable (neutral liquid)
Melting Point: Below -20°C
Boiling Point: Approximately 110–115°C at 13 mmHg (low pressure required to avoid decomposition)
Flash Point: Approximately 110°C (closed cup, supplier data)
Vapor Pressure: ~0.01 mmHg at 25°C (low volatility)
Solubility: Slightly soluble in water, miscible with most organic solvents
Density: ~1.07 g/cm3 at 25°C
Viscosity: 20–40 cP at 25°C
Partition Coefficient (log Kow): Approx. 2.5–3
Autoignition Temperature: >200°C
Chemical Stability: Stable under recommended storage, light exposure may trigger polymerization
Conditions to Avoid: High temperatures, UV light, strong oxidizers, uncontrolled mixing with acids or bases
Materials to Avoid: Free radical sources (peroxides, azo compounds), oxidizing agents
Polymerization: May occur due to heat, contamination, or absence of stabilizer, exothermic reaction possible
Decomposition Products: Acrylates, carbon oxides, organic acids
Inhibitor Content: Usually stabilized with MEHQ or similar additive; check lot certificate
Likely Routes of Exposure: Skin, eyes, inhalation
Acute Toxicity: Oral LD50 (rat): >2000 mg/kg (low acute toxicity expected); inhalation data not established due to low volatility
Skin Corrosion: May cause moderate to severe irritation with prolonged contact; risk of allergic contact dermatitis
Eye Damage: Causes irritation, possible reversible injury
Respiratory Sensitization: Irritation possible if aerosols or vapors inhaled, rare cases of sensitization documented for related acrylates
Chronic Effects: Repeated exposure may cause skin sensitization, eczema, no proven long-term systemic toxicity
Carcinogenicity: Not listed by IARC, NTP, or OSHA
Mutagenicity: Not expected based on related structures, negative bacterial reverse mutation assay
Reproductive Effects: No data available, avoid unnecessary exposure
Toxicity to Aquatic Life: EC50 (Daphnia, 48hr): 10–100 mg/L (estimate based on acrylic esters, avoid release to water)
Persistence/Degradability: Expected to undergo biodegradation, but slower due to acrylic functional groups
Bioaccumulation Potential: Moderate, log Kow suggests some potential to concentrate in organisms
Mobility in Soil: Moderate, will adsorb to organic matter
Other Adverse Effects: Large spills threaten aquatic organisms due to toxic and oxygen-demanding breakdown
Precautions: Chemical should not enter drains, soil, or waterways untreated
Waste Treatment Methods: Dispose as hazardous organic chemical waste, incinerate with flue gas scrubbing
Waste Code: Check local regulations; often listed under EPA Hazardous Waste Code U-listed chemicals
Disposal of Packaging: Contaminated containers should be triple-rinsed then either recycled or landfilled in compliance with regulations
Precautions: Prevent uncontrolled polymerization, do not discharge to surface water or municipal sewer
