Polyether F-38 (Poloxamer 108) is a block copolymer of ethylene oxide and propylene oxide. It appears as a colorless to light yellow transparent liquid or paste at room temperature, with no obvious irritating odor. This product is non-flammable and non-explosive, classified as a general chemical rather than a hazardous material. It is chemically stable under normal storage and handling conditions and does not decompose under typical storage conditions.
Based on toxicological data, Polyether F-38 exhibits excellent safety: acute oral toxicity (rat) LD₅₀ > 5 g\/kg, classified as low toxicity; it is non-irritating to rabbit skin and non-sensitizing; it only causes mild reversible conjunctival redness and swelling in the eyes. Ecologically, this product is readily biodegradable (OECD 301B standard, degradation rate >60%), and shows low toxicity to aquatic organisms (fish\/daphnia LC₅₀\/EC₅₀ > 100 mg\/L). It is not classified as hazardous to the aquatic environment.
Despite the low risk, caution is still required in industrial operations: avoid contact with strong oxidizing agents. Combustion may produce carbon monoxide, carbon dioxide, and other irritating or toxic fumes. Low temperatures (below 5°C) may cause the product to solidify or become cloudy, but it can be restored to its original state by warming and stirring evenly, without affecting product quality.
| Storage Condition | Specific Requirements |
|---|---|
| Warehouse Environment | Cool, dry, well-ventilated, away from ignition sources, heat sources, and incompatible substances |
| Temperature Control | Recommended storage temperature: 5°C – 40°C |
| Packaging Management | Keep containers tightly closed to prevent moisture and contamination |
| Shelf Life | Typically one year for unopened containers |
| Special Note | Empty containers may contain product residues; do not use for other purposes without proper treatment |
| Incident Type | Handling Method |
|---|---|
| Skin Contact | Immediately remove contaminated clothing and flush skin with plenty of running water and soap for at least 15 minutes. If irritation or discomfort occurs, seek medical attention. |
| Eye Contact | Immediately lift eyelids and flush with running water or saline for at least 15 minutes. Given the possibility of reversible conjunctival redness, seek professional medical care immediately after flushing. |
| Inhalation | Move to fresh air quickly and keep respiratory tract clear. If breathing difficulties or other discomfort occur, seek medical attention immediately. |
| Ingestion | Rinse mouth thoroughly with water. Do not give anything by mouth to an unconscious person. If feeling unwell, seek medical help immediately and show the safety data sheet. |
| Small Spill | Absorb with inert absorbent material (e.g., dry sand, vermiculite), collect with non-sparking tools into a closed container for disposal. |
| Large Spill | Contain spill area to prevent spread; suppress vapors with foam. Dispose of waste through a licensed professional waste disposal facility in accordance with regulations. |
Waste disposal must comply with national and local environmental regulations. It is recommended to incinerate or undergo other compliant disposal by a unit holding a hazardous waste operation permit. Do not discharge into drains or the natural environment.
