Other Hazards: Not classified as a PBT or vPvB substance. Not known to present flammability, reactivity, or chronic health risk under typical workplace conditions.
Chemical Name: Polyoxyethylene-Polyoxypropylene Block Copolymer
CAS Number: 9003-11-6
Percent: 100%
Impurities/Additives: No hazardous impurities above regulatory disclosure limits.
Molecular Formula: (C3H6O.C2H4O)x
Structure: Block copolymer with alternating propylene and ethylene oxide units
Inhalation: Remove person to fresh air. Seek medical advice if symptoms persist.
Skin Contact: Remove contaminated clothing. Immediately wash affected skin with soap and water. Seek medical attention for persistent irritation.
Eye Contact: Rinse eyes with plenty of water for at least 15 minutes, holding eyelids open. If discomfort remains, seek medical attention.
Ingestion: Rinse mouth and drink water. Do not induce vomiting. Seek medical advice if symptoms develop.
Specific Treatment: Symptomatic and supportive treatment recommended.
Suitable Extinguishing Media: Water spray, foam, dry chemical, or carbon dioxide can be used.
Unsuitable Extinguishing Media: Water jet may spread the product.
Fire Hazards: Product may burn if strongly heated. Combustion releases carbon oxides and low-molecular weight organic compounds.
Protective Equipment: Firefighters need self-contained breathing apparatus plus full protective gear.
Other Advice: Prevent contaminated runoff from entering drains or watercourses.
Personal Precautions: Use gloves, goggles, and appropriate clothing for clean-up. Slippery surfaces may create fall hazards.
Environmental Precautions: Prevent large spills entering waterways or drainage. Minimize runoff with earth or sand barriers.
Methods for Clean Up: Soak up small spills with inert absorbents. Place residue in suitable closed containers for disposal. Wash spill area thoroughly with water. For large spills, dike and pump material into salvage tanks.
Handling: Use only with adequate ventilation. Avoid direct contact with eyes and skin. Wash hands after handling. No eating, drinking, or smoking in use areas.
Storage: Store in tightly closed containers at 5–35°C in a dry, well-ventilated space. Keep away from incompatible materials such as strong oxidizers. Protect against freezing and moisture intrusion. Maintain good housekeeping to prevent slip risks.
Exposure Limits: No exposure limits established for this substance.
Engineering Controls: Use local exhaust or general ventilation during processing or bulk handling.
Personal Protective Equipment: Safety goggles and chemical-resistant gloves help prevent contact; for large-scale handling, use coveralls. Respiratory protection can be needed if significant aerosol or vapor is generated. Wash thoroughly after handling. Provide eyewash stations in work areas.
Appearance: Clear, colorless to slightly yellow liquid or waxy solid, depending on molecular weight.
Odor: Mild, characteristic
Odor Threshold: Not determined
pH (10% solution): 6–8
Melting Point/Freezing Point: Typically 0–60°C (molecular weight dependent)
Boiling Point: >150°C (decomposes)
Flash Point: Typically >200°C (closed cup)
Evaporation Rate: Negligible
Flammability: Not classified as flammable
Vapor Pressure: Very low

Partition Coefficient: log Kow: -1 to 1
Auto Ignition Temperature: >350°C
Decomposition Temperature: Above 150°C can start to decompose
Viscosity: Range varies with grade (liquids to pastes)
Chemical Stability: Stable under recommended storage and handling conditions.
Incompatible Materials: Strong oxidizers like nitric or sulfuric acid may degrade the product.
Hazardous Reactions: No dangerous polymerization reported.
Decomposition Products: Burning or thermal decomposition may produce carbon oxides, low-molecular fragments like formaldehyde.
Acute Toxicity: Low toxicity by oral, dermal, inhalation routes.
Skin Corrosion/Irritation: May cause slight, reversible irritation after prolonged contact.
Eye Damage/Irritation: May cause mild, transient irritation.
Respiratory or Skin Sensitization: Not sensitizing based on available data.
Germ Cell Mutagenicity: Not mutagenic in standard tests.
Carcinogenicity: No evidence in animals or reports on humans.
Reproductive Toxicity: No developmental or reproductive effects seen in standard studies.
Repeated Dose Toxicity: High doses may cause non-specific effects such as diarrhea.
Ecotoxicity: Not expected to pose acute risks to aquatic organisms at typical use concentrations. High concentrations may affect oxygen transfer or cause physical fouling.
Persistence and Degradability: Readily biodegradable under aerobic conditions according to OECD guidelines.
Bioaccumulative Potential: Low, based on log Kow values and water solubility.
Mobility in Soil: High water solubility leads to moderate mobility; binding to sediment unlikely.
Other Adverse Effects: No specific toxicity reported for terrestrial or aquatic wildlife under practical use conditions.
Waste Treatment Methods: Dispose of surplus product, residues, and containers via licensed waste services.
Product Disposal: Incineration or chemical landfill according to local regulations.
Packaging Disposal: Empty containers thoroughly before recycling or disposal. Avoid release to land or water systems.
UN Number: Not regulated for ground, air, or sea transport.
Proper Shipping Name: Not classified as hazardous for transport.
Transport Hazard Class: Not assigned.
Packing Group: Not regulated.
Environmental Hazards: Not a marine pollutant.
Special Precautions: Transport in closed containers upright, prevent container damage and leaks. No special requirements beyond standard good practice.
Safety, Health, and Environmental Regulations: Not subject to chemical inventory or control as a hazardous substance in the US (TSCA), EU (REACH), or most major countries.
Labeling Requirements: Signal words, hazard pictograms, and precautionary statements only needed for certain regulatory applications.
Other: For workplace use, safety data must be available to employees; SDS must be reviewed regularly as regulations and data change. Check local and international rules for special use categories, such as food or pharmaceuticals.
