Other Ingredients: None presenting harm at a reportable level
Eye Contact: Rinse with flowing water for several minutes, remove contact lenses if present, seek medical attention if discomfort persists
Skin Contact: Wash gently with soap and water, remove contaminated clothing, seek further care if irritation shows
Inhalation: Move to fresh air, use oxygen or artificial respiration in severe cases, consult medical staff if symptoms arise
Ingestion: Wash mouth with water, avoid inducing vomiting, seek physician’s help if symptoms last
Suitable Extinguishing Media: Use water spray, dry chemical, CO2, or foam to put out flames
Unsuitable Extinguishing Media: Pressurized water could spread fire containing the chemical
Protective Equipment: Self-contained breathing apparatus and chemical-resistant protective gear
Hazardous Combustion Products: Breathing smoke might expose to carbon monoxide, carbon dioxide, various hydrocarbons
Fire and Explosion Risks: Combustion possible if heated above its flash point (over 115°C); spilled liquid can create slippery floors
Personal Precautions: Wear suitable protective gloves, safety glasses, avoid breathing vapors
Environmental Precautions: Prevent runoff from entering waterways, soil, or drains
Containment Methods: Soak up with sand, earth, or chem-sorbent pads, shovel into proper disposal drums
Cleanup Procedures: Wash affected area with detergent and plenty of water, ventilate confined spaces during cleanup
Safe Handling Advice: Maintain adequate ventilation, avoid splashing or direct contact, do not eat, drink, or smoke in use areas
Storage Conditions: Store in tightly closed original container in a cool, dry, well-ventilated place away from oxidizers, strong acids, or bases
Incompatibility: Oxidizing agents, strong acids
Packaging Materials: Suitable for lined steel or high-density polyethylene containers
Temperature Guidelines: Keep below 40°C for optimal shelf life
Workplace Exposure Limits: No established ACGIH TLV or OSHA PEL; use general standards for glycol vapors
Engineering Controls: General exhaust ventilation recommended, eye-wash stations, and emergency showers nearby
Eye Protection: Use chemical safety goggles or face shield
Skin Protection: Impermeable gloves (nitrile, butyl rubber), protective clothing
Respiratory Protection: Not usually necessary under normal conditions; use mask or respirator when vapors become excessive
Hygienic Measures: Regular handwashing, remove contaminated clothing, avoid eating and drinking in handling areas
Appearance: Clear, colorless to pale yellow liquid
Odor: Little to none, faint sweet odor if any
Boiling Point: Approx. 231°C
Melting Point: Approx. -68°C
Flash Point: Around 115°C (open cup)
Solubility: Fully soluble in water; mixes well with alcohols and esters
Vapor Pressure: Very low at room temperature
Viscosity: Higher than water; typical of glycols
Density: 1.02–1.03 g/cm3 at 20°C
Partition Coefficient (log Kow): -0.3
pH Value: Neutral (6–7)
Chemical Stability: Remains stable under proper storage conditions
Reaction Risks: Will not react under normal usage; exposure to strong acids, bases or oxidizers can cause breakdown
Conditions to Avoid: Prolonged heat, open flames, and sources of ignition
Hazardous Decomposition: Uncontrolled fire or heat produces carbon monoxide, carbon dioxide, and other organics
Polymerization: No dangerous polymerization expected
Possible Exposure Routes: Skin, eyes, inhalation, ingestion
Acute Toxicity: LD50 (oral, rat) ~15,000 mg/kg (low toxicity)
Skin Corrosion / Irritation: Mild irritation possible with prolonged or repeated exposure
Serious Eye Damage / Irritation: Could cause transient eye irritation
Respiratory Effects: Irritation can occur at high airborne concentrations
Sensitization: Skin sensitizer potential is very low
Carcinogenicity: Not listed by IARC, ACGIH, NTP, or OSHA as a carcinogen
Mutagenicity: Not mutagenic based on available studies
Reproductive Toxicity: No evidence of adverse reproductive effects in animal studies
Ecotoxicity: Not highly toxic to fish or aquatic invertebrates; LC50 (fish, 96 hr): ~10,000 mg/L
Persistence: Degrades readily in environment; does not bioaccumulate
Mobility: Highly mobile in water, low potential for adsorption to soils
Bioaccumulation Potential: Very low, log Kow below 1
Degradability: Expected to fully biodegrade under aerobic conditions
Impact on Wastewater Plants: Low concentrations pose little threat, but repeated spills should be avoided
Recommended Waste Management: Dispose as non-hazardous waste if uncontaminated, following local, regional, and national regulations
Incineration: Approved chemical incinerators acceptable if unrecoverable
Waste Containers: Use standard chemical drums with correct labeling
Precautions: Avoid dumping into surface water, ground, or public sewers
Clean Packaging: Containers can be recycled or disposed after thorough decontamination
UN Number: Not regulated for the majority of ground, air, or sea transport
Proper Shipping Name: Dipropylene Glycol
Transport Hazard Class: Not classified as hazardous
