L-62 Poloxamer (CAS: 9003-11-6) is a nonionic block copolymer precisely composed of polyethylene oxide (PEO) and polypropylene oxide (PPO) segments, with an average molecular weight of approximately 2500. The unique arrangement of hydrophilic and hydrophobic blocks in its molecular structure endows the product with excellent low-foaming and foam control properties, making it particularly suitable for foam-sensitive formulations such as automatic dishwasher rinse aids and hard surface cleaners, effectively preventing overflow foaming and improving rinsing efficiency.
This product can rapidly reduce the surface tension of aqueous solutions, demonstrating strong dispersing and wetting effects on pigments, dirt, and solid particles, ensuring a uniform and stable system. Meanwhile, L-62 maintains high chemical stability under harsh conditions such as acids, alkalis, and hard water, with performance unaffected by complex water quality and extreme pH environments, showing excellent formulation compatibility in industrial applications.
As a multifunctional emulsifier, L-62 can be used alone as the primary emulsifier or combined with other surfactants for auxiliary emulsification, providing fine and stable emulsion systems in scenarios such as emulsion polymerization, pesticide formulations, and coating dispersion. At room temperature, the product appears as a colorless to slightly yellow transparent oily liquid with good fluidity and pumpability, facilitating industrial continuous production operations.

Core Recommended Scenarios: Automatic dishwasher rinse aids (providing spot-free and streak-free fast drying), hard surface cleaners (low-foaming wetting and penetration), industrial defoamers (long-lasting foam suppression), metalworking fluids (low-foaming wetting and cooling), pesticide emulsifiers and spreaders, emulsion polymerization emulsifiers, and water-based pigment/filler dispersants.
The typical dosage in formulations varies depending on the specific application system; it is recommended to determine the optimal addition amount through gradient experiments. L-62 can be used alone or in combination with nonionic, anionic, or cationic surfactants to achieve synergistic effects.
