Chemical Name: Hydroxypropyl Acrylate Synonyms: 2-Hydroxypropyl Acrylate CAS Number: 25584-83-2 Appearance: Clear to light yellow liquid Odor: Mild acrylic scent Molecular Formula: C6H10O3 Common Uses: Intermediate for polymers, coatings, adhesives
Health Hazards: Irritates skin, eyes, and respiratory tract; may cause allergic skin reactions; inhalation can cause headaches and dizziness Flammability Risks: Combustible liquid and vapor; can form explosive mixtures with air at elevated temperatures Environmental Risks: Harmful to aquatic life with long-lasting effects; spills threaten water sources and soil Symbols: GHS07 Exclamation Mark, GHS09 Environment Signal Word: Warning
Chemical Name: 2-Hydroxypropyl Acrylate Concentration: Typically above 95% Impurities: Trace amounts of acrylic acid, inhibitors like MEHQ Relevant Additives: Stabilizers to prevent premature polymerization may be present
Inhalation: Remove from exposure, move to fresh air, seek medical help if symptoms persist Skin Contact: Remove contaminated clothing, rinse skin with plenty of water for at least 15 minutes, seek treatment for irritation Eye Contact: Flush open eyes with lukewarm water for several minutes, do not rub eyes, seek immediate medical attention for persistent discomfort Ingestion: Rinse mouth, do not induce vomiting, seek medical attention if any symptoms appear Notes for Doctors: Treat symptoms, consider observation for delayed effects from sensitization
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide Hazards in Fire: Releases toxic vapors like carbon monoxide, carbon dioxide, irritating acrid smoke Firefighters' Protection: Use self-contained breathing apparatus and full protective gear Special Recommendations: Cool containers exposed to fire with water spray to prevent pressure buildup Specific Risks: Vapors heavier than air could accumulate in low areas, increasing explosion risk
Personal Precautions: Wear chemical-resistant gloves, goggles, and protective clothing; ventilate area Environmental Measures: Prevent entry into sewers and waterways; absorb spill with inert material Cleanup Methods: Use non-sparking tools, collect residue in sealable containers, dispose of as hazardous waste Decontamination: Wash spill area with plenty of water after cleanup
Precautions for Handling: Avoid inhaling vapors and contact with skin or eyes; handle only with proper ventilation Storage Conditions: Store tightly closed in a cool, dry, well-ventilated area away from direct sunlight and heat sources Storage Incompatibilities: Keep away from oxidizers, acids, bases, strong reducing agents General Practices: Use explosion-proof equipment and bonding/grounding to avoid static discharge
Engineering Controls: Provide local exhaust or general ventilation to maintain vapor levels below limits Personal Protective Equipment (PPE): Nitrile or neoprene gloves, chemical goggles or face shield, lab coat or chemical apron Respiratory Protection: Approved respirator for organic vapors when exposure may exceed limits Hygiene Measures: Wash hands before breaks and after work, remove contaminated clothing Workplace Monitoring: Implement regular air monitoring to check acrylate vapor levels
Physical State: Liquid Color: Colorless to pale yellow Melting Point: -53°C Boiling Point: 170–176°C Flash Point: Around 75°C (closed cup) Vapor Density: Heavier than air Solubility: Miscible with water and most organic solvents Odor Threshold: Detectable at low concentrations, but not a safe indicator for overexposure Viscosity: Low to moderate
Chemical Stability: Stable with proper inhibitors under recommended storage Possibility of Hazardous Reactions: Uninhibited monomer can polymerize violently; exposure to heat, light, or contamination triggers rapid reaction Incompatible Materials: Oxidizing agents, acids, bases, amines Decomposition Products: Carbon monoxide, carbon dioxide, smoke, acrid fumes
Acute Effects: Causes skin, eye, and respiratory tract irritation; may cause sensitization, leading to allergic reactions on repeated exposure Chronic Effects: Prolonged or repeated skin contact can worsen dermatitis, aggravate respiratory symptoms Toxicity Data: Oral and dermal LD50 reported in the low to moderate range in animals Carcinogenicity: Not classified as a human carcinogen by IARC, NTP, or OSHA Other Effects: Data on reproductive toxicity and mutagenicity remain inconclusive
Acute Ecotoxicity: Toxic to aquatic organisms at relatively low concentrations Persistence and Degradability: Slow to biodegrade under aerobic conditions Bioaccumulation Potential: Low, based on partition coefficient Mobility in Soil: Readily mobile and can leach through soil into groundwater Danger to Environment: Spills or improper disposal contaminate water and harm local wildlife
Waste Disposal Methods: Incinerate in approved facilities with proper pollution controls, avoid landfill disposal whenever possible Container Disposal: Rinse empty containers thoroughly, follow local and federal hazardous waste procedures Precautions: Do not flush into surface water or sewage
UN Number: Regulated as hazardous for transport, often assigned UN 1993 or related numbers Transport Hazard Class: Flammable liquid Packing Group: Group III, moderate hazard Special Transport Requirements: Keep in upright position, protect from physical damage, mark all packages with flammable labels Regulatory Oversight: Subject to transport rules set by DOT, ICAO, IMO, and similar bodies
Workplace Standards: Subject to OSHA hazard communication and EPA chemical inventory regulations Labeling: Requires GHS-compliant labeling for all containers Community Right-to-Know: Often listed under local and federal chemical safety programs Import/Export Controls: Falls under certain national controls for shipping chemicals of concern Additional Restrictions: Some regions restrict use in consumer products due to sensitization risk
