Chemical Name: Lauryl Acrylate
CAS Number: 2156-97-0
Concentration: > 99%
Impurities: May include traces of acrylic acid, hydroquinone (inhibitor)
Additives: Often stabilized with up to 100 ppm hydroquinone or MEHQ to prevent polymerization during storage and transport
Inhalation: Move exposed person to fresh air, keep at rest in comfortable position, seek medical advice if symptoms persist
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water, seek medical attention for persistent irritation
Eye Contact: Rinse eyes cautiously with clean water for at least 15 minutes, remove contact lenses if present, consult medical personnel if irritation occurs
Ingestion: Rinse mouth, do not induce vomiting, seek medical help promptly
Symptoms: Redness, irritation, itching, possible respiratory discomfort, headache, nausea if overexposed
Suitable Extinguishing Media: Dry chemical, alcohol-resistant foam, CO2, water spray (do not use direct water jet)
Specific Hazards: Vapors may form explosive mixtures with air, thermal decomposition releases acrid smoke, carbon monoxide, and carbon dioxide
Protective Equipment: Firefighters should use full protective gear including self-contained breathing apparatus
Special Precautions: Cool exposed containers with water spray to avoid pressure buildup, avoid runoff into sewers and waterways
Personal Precautions: Evacuate area of unprotected personnel, ventilate space, avoid inhalation and skin contact
Environmental Precautions: Prevent entry into drains, sewers, or waterways, notify authorities if large spill occurs
Methods for Clean-Up: Absorb with inert material (sand, vermiculite), collect mechanically, transfer to labeled leakproof containers for disposal, wash area with detergent and water after collection
Precautions for Safe Handling: Use in well-ventilated area, keep away from heat sources, sparks, or open flame, avoid contact with eyes and skin, avoid inhalation of vapor
Storage Conditions: Store in tightly closed, properly labeled containers in a cool, dry, ventilated area away from direct sunlight, ignition sources, and incompatible materials like oxidizers, acids, and bases
Incompatibilities: Avoid storage with strong oxidizing agents, acids, bases, or free radical initiators which can cause dangerous reactions including rapid polymerization
Exposure Limits: No specific occupational exposure limits established, but limit exposure to lowest practicable through proper controls
Engineering Controls: Use mechanical exhaust, capture vapors at point of generation, ensure equipment is explosion-proof
Personal Protection: Wear chemical-resistant gloves (e.g., nitrile), safety goggles or face shield, impervious clothing, and suitable respiratory equipment if airborne exposure possible
Hygiene: Wash hands thoroughly after handling, do not eat or drink in work areas, remove contaminated clothing promptly

Volatility: Low
Partition Coefficient (log Kow): Estimated 4.7
Auto-Ignition Temperature: 270°C
Explosive Limits: Not determined
Chemical Stability: Stable in original container under recommended storage conditions with inhibitor
Polymerization: May polymerize violently under heat, light, or contamination by peroxides, free radical initiators, or strong acids and bases if inhibitor concentration falls
Hazardous Decomposition: Burning may produce acrid smoke, carbon dioxide, carbon monoxide
Conditions to Avoid: Exposure to heat, direct sunlight, strong oxidizers, and initiators
Incompatible Materials: Strong acids, bases, peroxides, free radical initiators
Acute Toxicity: Oral LD50 (rat): > 5,000 mg/kg; Dermal LD50 (rabbit): > 2,000 mg/kg
Inhalation: May cause headache, dizziness, respiratory tract irritation at high concentrations
Skin Contact: Causes irritation, prolonged exposure may lead to sensitization
Eye Contact: Causes irritation
Chronic Effects: Possible skin sensitization after repeated contact
Carcinogenicity: Not classified as carcinogenic by IARC, NTP, or OSHA
Mutagenicity/Reproductive Toxicity: Existing animal studies show little evidence of mutagenicity or reproductive toxicity at expected exposure levels
Ecotoxicity: Toxic to aquatic organisms, may cause long-term adverse effects in aquatic environment
Persistence/Degradability: Not readily biodegradable, slow degradation in soil and water
Bioaccumulation: Potential to bioaccumulate in aquatic organisms, log Kow indicates moderate to high tendency
Mobility: Limited mobility in environment due to low solubility, but vapor may disperse in air and deposit on surfaces
Environmental Impact: Spill or large release may cause damage to aquatic life, disrupt plant and microbial communities
Waste Treatment: Collect residue in sealed, labeled containers, dispose of through licensed hazardous waste facility
Incineration: Suitable method under controlled conditions to avoid emission of toxic byproducts
Avoid Release: Do not pour into drains, surface water, soil, or natural environment
Packaging: Triple rinse empty containers, destroy or recycle per local regulations, avoid reuse for other products
