Chemical Name: Glycerol 1,3-Dimethacrylate
CAS No.: 1830-78-0
Concentration: > 95% (pure substance; varies with formulation)
Impurities: Monomethacrylates, hydroquinone, other stabilizers in low concentrations depending on manufacturer
Additives: Traces of inhibitors to prevent polymerization during storage
Inhalation: Remove the affected person to fresh air; provide oxygen or artificial respiration for severe respiratory symptoms; seek medical advice if irritation or breathing difficulties continue
Skin Contact: Immediately flush affected skin with soap and running water for at least 15 minutes; remove contaminated clothing and shoes; medical attention required if irritation develops or persists
Eye Contact: Rinse eyes thoroughly with water for at least 15 minutes, including under eyelids; lift eyelids repeatedly; get medical attention if irritation or pain persists
Ingestion: Rinse mouth with water; do not induce vomiting unless directed by a medical professional; call poison control for advice and seek medical attention right away
Most Important Symptoms: Redness, swelling, allergic reactions—particularly with repeated exposure
Suitable Extinguishing Media: Use dry chemical, foam, or carbon dioxide extinguishers; water spray can help cool containers but might not put out the fire itself
Specific Hazards Arising from Chemical: Produces irritating and toxic fumes when burned, including carbon monoxide, carbon dioxide, and unknown methacrylate compounds
Protective Equipment: Firefighters should put on self-contained breathing apparatus and full body protection
Unusual Fire or Explosion Hazards: Vapors accumulate in low-lying areas, risk of flashback; leaks can spread fire far from ignition source
Advice for Firefighters: Approach fire from upwind; keep containers cool with water spray if safe; prevent run-off into sewers and waterways
Personal Precautions: Evacuate area and ventilate, avoid inhaling vapors; keep away from ignition sources; use personal protective equipment including goggles, gloves, suitable respirator
Environmental Precautions: Prevent spill from reaching drains or surface waters; report releases to appropriate agencies as required by law
Containment and Cleanup: Use inert absorbent materials (such as sand or vermiculite) to collect liquid; transfer to proper waste disposal containers; wash area with plenty of water; ventilate site completely before re-entry
Safe Handling: Use only with adequate ventilation; do not eat, drink, or smoke while working; avoid splashes and minimize contact with skin and eyes; never use near open flames or heat, as product may ignite
Storage Conditions: Store in cool, dry, well-ventilated place away from heat and direct sunlight; keep container tightly closed when not in use; keep away from oxidizing agents, acids, and bases
Special Considerations: Routine inspection recommended for leaks or degradation; do not allow storage temperature to exceed 30°C (86°F); keep stabilization agents sealed within original packaging
Occupational Exposure Limits: No established limits specific for this substance, but control exposure as with other acrylate monomers
Engineering Controls: Local exhaust ventilation at points of vapor generation; use closed systems when possible
Personal Protective Equipment (PPE): Chemical-resistant gloves (nitrile or latex), safety goggles or face shield, protective lab coat or apron, suitable organic vapor respirator for high vapor formation or confined spaces
Hygiene Measures: Wash hands thoroughly after use and before breaks; do not reuse contaminated clothing; follow good chemical hygiene practices at all times
Appearance: Colorless to pale yellow liquid
Odor: Faint, characteristic methacrylate
Odor Threshold: Not easily detectable at safe levels
pH: Not applicable (liquid ester)
Melting Point/Freezing Point: Below 0°C
Boiling Point: Decomposes above 200°C
Flash Point: Approximately 110°C (closed cup)
Evaporation Rate: Slower than water
Flammability: Combustible liquid
Vapor Pressure: <1 mmHg at 20°C
Vapor Density: Heavier than air
Solubility: Slightly soluble in water; miscible with most organic solvents
Partition Coefficient: log Kow about 1.5–2.0
Auto-Ignition Temperature: About 250°C
Decomposition Temperature: Polymerizes and decomposes above boiling
Viscosity: Moderate at room temperature
Chemical Stability: Stable under recommended storage conditions; sensitive to heat, light, peroxide impurities; may polymerize without proper inhibitor
Conditions to Avoid: Direct sunlight, elevated temperatures, sources of ignition, contamination with most metal ions, strong acids or bases
Incompatible Materials: Strong oxidizers, peroxides, iron and copper salts, acids, alkalis
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, various acrylate derivatives
Hazardous Polymerization: Can occur in absence of stabilizer and with exposure to heat or contamination
Acute Toxicity: Low acute toxicity by oral and dermal routes; higher doses may cause gastrointestinal discomfort or central nervous system depression in animal studies
Skin Irritation: Prolonged or repeated contact causes redness, burning, dermatitis; can sensitize skin and trigger allergic reactions
Eye Contact: Direct contact results in tearing, burning, severe irritation
Inhalation: Inhalation of vapors triggers coughing, headache, potential allergic sensitization, and respiratory tract irritation
Chronic Effects: Skin and airway sensitization; risk of developing eczema or asthma after repeated exposure
Other Risks: Animal studies suggest possible reproductive toxicity with high exposure; insufficient data in humans
Carcinogenicity: No evidence tying substance directly to cancer in standard animal tests; not listed by IARC, ACGIH, NTP, OSHA
Aquatic Toxicity: Harmful to aquatic life with long-lasting effects, particularly sensitive to aquatic invertebrates
Persistence and Degradability: Does not break down easily in the environment; expected to degrade slowly by hydrolysis and photolysis
Bioaccumulative Potential: Moderate bioaccumulation possible; monitoring recommended where releases to water systems occur
Mobility in Soil: Leaches modestly in soil; can travel short distances in groundwater depending on site conditions
Other Environmental Effects: Very low vapor pressure limits atmospheric spread; emergency spill plans should focus on containment to water and soil
Waste Disposal Methods: Send residues to licensed chemical incinerator or approved hazardous waste facility; never pour unused material into drains, streams, or onto ground
Container Safety: Triple-rinse empty containers before disposal; deface label prior to container recycling as scrap
Regulations: Dispose in accordance with local, regional, and national environmental regulations; documentation or manifest required for large quantities; do not attempt open burning
