Precautions: Avoid breathing mist or vapor, wear gloves and goggles, ensure good ventilation, wash hands thoroughly after use, prevent contact with eyes and skin
Dimethyl Glutarate: 50–70% (CAS 1119-40-0)
Dimethyl Adipate: 15–25% (CAS 627-93-0)
Dimethyl Succinate: 10–25% (CAS 106-65-0)
Impurities: Less than 0.2% total, trace volumes of other methyl esters
Purity: Greater than 99% for main blend components, product comes as a nearly colorless liquid
Eye Contact: Rinse immediately with plenty of clean water, hold eyelids open for full 15 minutes, remove contacts if present
Skin Contact: Wash off with soap and flowing water, remove soiled clothing or shoes
Inhalation: Move to fresh air, keep resting, supply oxygen if breathing feels labored, seek medical care if unwell
Ingestion: Rinse mouth, do not induce vomiting, drink water, call medical services right away
Key Symptoms: Eye and skin redness or burning sensation, persistent coughing or shortness of breath in case of inhalational exposure
Suitable Extinguishing Media: Water fog, carbon dioxide, dry powder, or foam
Specific Hazards: Vapors can form explosive mixtures with air, combustion releases carbon oxides, alarms triggered from strong smoke
Protective Gear: Firefighters wear complete protective clothing, including self-contained breathing apparatus to avoid respiratory tract irritation by fumes
Recommendations: Cool containers nearby with water mist, keep escape routes clear, isolate spill area from ignition sources, use regular firefighting procedures for liquid chemical fires
Personal Protection: Evacuate spill area, equip personnel with gloves, goggles, and splash aprons, avoid inhaling vapor
Environmental Precautions: Prevent entry into drains, soil, or groundwater, dike spillage with earth or inert material for collection
Containment and Cleanup: Ventilate affected area, absorb with non-combustible material (sand or earth), collect residue in suitable disposal container, clean traces with detergent, do not wash away with large amounts of water
Handling Advice: Handle in areas with exhaust or local fume extraction, wear gloves and goggles, prevent all skin and eye contact, avoid eating or drinking during use
Storage: Store drums or containers tightly closed in cool, dry, well-ventilated storerooms, keep away from heat, sparks, and flames, do not freeze, separate from oxidizers and acids
Industrial Hygiene: Wash hands after handling, change clothes if spilled, ensure proper labeling and warning signage
Exposure Limits: No established OSHA or ACGIH TLVs for core components, stay below 5–10 ppm for good practice
Engineering Controls: Use local exhaust in blending and open processing, ensure good air flow near tanks or maintenance
Protective Equipment: Chemical-resistant gloves (nitrile or butyl rubber), tight-fit goggles, splash-proof aprons, use respirator with organic vapor cartridge for big spills or cleaning tanks
Hygiene: Remove contaminated clothing after work, wash hands and forearms thoroughly
Form: Clear, almost colorless liquid
Odor: Mild, ester-like scent, not sharp or overpowering
Boiling Point: 196-230°C (384-446°F) depending on ratio of blend
Melting Point: -20°C to -2°C
Flash Point: 92–102°C (closed cup)
Density: About 1.09 g/cm³ at 20°C
Solubility: Soluble in most organic solvents; slightly soluble in water
Vapor Pressure: Low, under 0.4 mmHg at 25°C
Evaporation Rate: Slower than water or acetone
Viscosity: About 2.1 mPa.s at 25°C
Chemical Stability: Stable under normal processing, shelf life exceeds two years if sealed and protected from moisture
Reactivity: No dangerous reaction occurs during normal use, keep away from strong acids, bases, oxidizers
Hazardous Decomposition: Carbon monoxide, carbon dioxide, trace acids if decomposition happens at high temperature
Polymerization: Product does not polymerize, risk of container rupture if sealed and heated excessively
Acute Toxicity: Oral LD50 (rat) > 5000 mg/kg; unlikely to cause poisoning if small amount swallowed
Skin Effects: Can irritate with frequent or prolonged contact, may cause redness and dryness
Eye Effects: Causes redness, watering, strong stinging on direct contact
Inhalation: Vapor can lead to headache, drowsiness, if large volume evaporates into workspace
Chronic Effects: No evidence for mutagenic, carcinogenic, or reproductive toxicity in standard tests, but always minimize exposure
Aquatic Toxicity: LC50 (fish, 96h) in range of 18–35 mg/L, toxic to aquatic species at high concentration
Persistence and Degradability: Biodegrades in soil and water within weeks, not persistent
Bioaccumulation: Log Kow below 1.5–2.5, not expected to build up in tissue
Mobility in Soil: Medium, moves into groundwater if spilled in large quantities, use dikes to stop runoff
Ecotoxicity: Large accidental spills can harm water plants, insects, and fish—collect all free liquid after accident
Waste Handling: Dispose as hazardous waste under RCRA or local rules, collect in sealed cans or drums
Disposal Methods: Incinerate in a chemical incinerator with afterburner and scrubber, do not pour down drains or landfill untreated
Packaging: Empty drums rinsed and offered for recycling, follow local container control laws, do not reuse for other chemicals
