Polyether L-44 (Poloxamer 124) appears as a colorless to light yellow transparent liquid and is easy to operate. According to the Guoli Chemical database, this product is soluble in water, ethanol, ether, and other common solvents, and can be directly added to the formulation system under stirring. The specific operation method depends on the application scenario: in polyurethane foam, it is usually used as a foam stabilizer and mixed with polyol, water, catalyst, and other components before foaming; in industrial cleaning and metalworking fluids, it is directly added to the aqueous phase system for dissolution, and if necessary, slight heating can be applied to accelerate dispersion; in agrochemical formulations, it is often premixed with oil-phase raw materials before emulsification; in personal care products, it is generally added in the later stage of the formulation and stirred evenly.
This product is resistant to acid, alkali, and hard water, has good chemical stability, and can be well compounded with anionic, cationic, and other nonionic surfactants, broadening its applicability in different complex systems.

Note: The Guoli Chemical product database does not provide specific dosage values for Polyether L-44 in various application fields. The following dosage ranges are empirical values commonly used in the industry; the actual dosage should be determined through formulation experiments and performance evaluation:
| Application Field | Function | Recommended Reference Dosage (as percentage of total formulation weight) |
|---|---|---|
| Polyurethane Foam (Flexible and Rigid) | Foam stabilizer, emulsifier, nucleating agent | 0.5%–2% |
| Polyurethane Coatings/Adhesives/Elastomers | Leveling agent, wetting agent | 0.2%–1% |
| Industrial Cleaners | Low-foaming surfactant, detergency and emulsification | 1%–5% |
| Metalworking Fluids | Lubrication, wetting, cleaning | 1%–3% |
| Pesticide Formulations (Emulsifiable Concentrates, Microemulsions) | Emulsifier, spreader | 2%–5% (by weight of oil phase) |
| Personal Care Products (Cosmetics) | Mild emollient, skin feel modifier | 0.1%–1% |
