Polyether L-44 (Poloxamer 124) is a nonionic polyether surfactant with stable chemical properties. It is not classified as a hazardous chemical and is not easily combustible, making storage relatively convenient. However, as a surfactant product, care should be taken to prevent moisture absorption and contamination to ensure performance consistency during use.
The key points for storage are: keep the container tightly sealed, away from heat sources and open flames, and avoid coexistence with strong oxidizers, strong acids, or strong alkalis. Although the product itself has a low freezing point, repeated freeze-thaw cycles should be avoided to prevent potential effects on appearance and uniformity. Before use, check that the container is intact and the label is clear.
Regarding the shelf life, the product database does not provide a specific duration (e.g., 1 year or 2 years), but it clearly states that performance remains stable within the shelf life under recommended storage conditions. Generally, industrial-grade polyether surfactants, when sealed properly, typically have a shelf life of 1–2 years. For specific recommendations, refer to the product packaging label or contact Guoli Chemical's technical service team for confirmation.
| Storage Element | Specific Requirement |
|---|---|
| Environment | Cool, dry, and well-ventilated warehouse |
| Temperature | Recommended not exceeding 40°C, avoid repeated freeze-thaw cycles |
| Container | Keep tightly sealed to prevent moisture absorption and contamination |
| Prohibitions | Away from heat sources, sparks, open flames; avoid coexistence with strong oxidizers, strong acids, and strong alkalis |
| Light | Avoid direct sunlight |
| Before Use | Check container integrity and label clarity |
Polyether L-44 is widely used in polyurethane foam, industrial cleaning, metalworking fluids, pesticide formulations, and personal care products. Storage conditions directly affect its core properties such as emulsification, wetting, dispersion, and low foaming. Especially when used in polyurethane foaming formulations, improper storage leading to moisture absorption or contamination may cause uneven foam structure or collapse. It is recommended to use the product promptly after opening.
