Polyether L-45 (CAS No.: 9003-11-6) belongs to the poloxamer class of nonionic surfactants. With its excellent emulsifying, wetting, and dispersing properties, as well as unique low-foaming characteristics, it plays a key role in multiple industrial fields. Its outstanding stability against acids and alkalis and strong resistance to hard water allow it to maintain activity under a wide range of pH conditions, making it a preferred raw material for formulation engineers designing efficient industrial auxiliaries.
In the cleaning industry, Polyether L-45 serves as an efficient low-foaming wetting agent that quickly penetrates and emulsifies heavy oil and grease, making it especially suitable for spray cleaning processes on metal and hard surfaces. In the field of dish drying, it significantly reduces the surface tension of rinse water, promoting uniform spreading and rapid detachment of the water film, so that dishes dry immediately upon exiting the machine without watermarks or spots. In metalworking fluids, its excellent foam suppression properties effectively prevent processing foam overflow, ensuring stability in high-pressure spraying and high-speed cutting.
Furthermore, Polyether L-45 demonstrates excellent penetration and dispersion capabilities in textile scouring and bleaching processes, efficiently removing cotton wax impurities and suspending soils to prevent redeposition. In pesticide formulations, it acts as an emulsifier, allowing oily active ingredients to automatically disperse into stable emulsions with uniform particle size. In the field of defoamers, its extremely low foaming tendency makes it a base carrier or synergistic component in industrial defoamer formulations.
| Application Industry | Specific Process/Scenario | Function/Role |
|---|---|---|
| Industrial Cleaning | Spray cleaning of metal and hard surfaces, heavy oil and grease cleaning | Low-foaming wetting and penetration, emulsifying heavy oil and grease, improving cleanliness |
| Dish Drying | Rinse and drying process in commercial dishwashers | Reduce surface tension of rinse water, promote rapid spreading and detachment of water film, achieve quick drying without spots |
| Metalworking | Cutting fluids, grinding fluids, high-pressure spray processing | Lubrication and cooling assistance, foam suppression to prevent overflow, ensure process stability |
| Textile Dyeing and Finishing | Desizing, scouring, bleaching processes | Penetration and dispersion, remove cotton wax impurities, suspend soils to prevent redeposition |
| Pesticide Formulations | Preparation of emulsifiable concentrates (EC) and oil-in-water emulsions (EW) | Emulsify oily active ingredients, form stable emulsions with uniform particle size |
| Defoamers | Base carrier in industrial defoamer formulations | Extremely low foaming tendency, synergistic foam control with silicone/mineral oil |
Based on specific process requirements, it is recommended to determine the optimal dosage of Polyether L-45 through small-scale trials during the formulation development stage. In industrial cleaning and dish drying applications, focus on balancing its low-foaming characteristics and wetting/spreading performance. In pesticide emulsification formulations, it is advised to conduct HLB value matching experiments to determine the optimal ratio with the active ingredient. This product can be stored stably at 5–35°C. If low temperature causes an increase in viscosity before use, proper warming can restore fluidity without affecting product performance.
