Polyether L-64 (Poloxamer 184, CAS No. 9003-11-6) is a block copolymer of propylene oxide and ethylene oxide. At room temperature, it appears as a colorless to light yellow transparent liquid. Its unique molecular structure—with a hydrophobic polyoxypropylene (PPO) segment in the middle and hydrophilic polyoxyethylene (PEO) segments on both sides—endows the product with multiple interfacial activities, making it widely applicable in many industrial fields.
The most prominent feature of this product is its "low-foaming and wetting integration": on one hand, it can rapidly reduce dynamic surface tension, achieving efficient wetting and spreading on various substrates; on the other hand, the foam generation in the working solution is extremely low and defoaming is rapid, making it especially suitable for foam-sensitive processes such as high-pressure spraying, circulating systems, and jet cleaning. This can reduce or even eliminate the need for additional defoamers.
In addition, Polyether L-64 maintains good stability in acids, alkalis, and high-hardness water; it has excellent compatibility with anionic, cationic, and other nonionic surfactants, and remains active over a wide pH range. It has good toxicological safety, low skin and eye irritation, and is widely used in cosmetics, personal care products, pharmaceutical preparations, and other fields with strict safety requirements.
