Polyether L-44, chemically named Poloxamer 124, also known commercially as Pluronic L-44, with CAS number 9003-11-6, is a polyoxyethylene polyoxypropylene ether block copolymer produced by Haian Guoli Chemical Co., Ltd. Its molecular structure alternates hydrophilic EO segments with hydrophobic PO segments, endowing it with unique amphiphilic properties that enable efficient orientation at oil-water interfaces, thereby exhibiting superior surface activity.
The product appears as a colorless to slightly yellow transparent liquid. As a nonionic surfactant, it possesses strong chemical stability and can withstand acidic, alkaline, and hard water environments without easily losing effectiveness. It is well compatible with anionic, cationic, and other nonionic surfactants, offering broad multifunctional compatibility. Additionally, Polyether L-44 features low skin irritation, no sensitization, and good biocompatibility. Its acute oral toxicity (rat) LD₅₀ is greater than 5000 mg/kg, classifying it as practically non-toxic with high safety for use.
In practical applications, Polyether L-44 widely covers multiple fields including the polyurethane industry (foam stabilizer, coating leveling agent), industrial cleaning (low-foam cleaning agents), metalworking fluids (lubrication and wetting components), pesticide formulations (emulsifier), and personal care products (mild emollient). It is a versatile, safe, and reliable industrial-grade surfactant.

Polyurethane Industry: Acts as an efficient foam stabilizer in formulations for flexible, rigid, and semi-rigid foams, providing excellent emulsification, nucleation, and cell refining functions; serves as a leveling agent and wetting agent in polyurethane coatings, adhesives, and elastomer systems to reduce defects such as craters and orange peel.
Industrial Cleaning: Used as a low-foaming surfactant in high-pressure spray and circulation cleaning formulations, offering low foam and rapid defoaming while providing good emulsification and detergency.
Metalworking Fluids: Provides lubrication, wetting, and cleaning effects to help extend tool life and improve workpiece surface quality, with synergistic anti-corrosion properties.
Pesticide Formulations: Used as an agrochemical emulsifier to enhance wetting and spreading of spray solutions, improve emulsification stability and dilution dispersibility of emulsifiable concentrates and microemulsions, thereby increasing efficacy utilization.
Personal Care Products: Serves as a mild emollient component in cosmetic formulations, providing a smooth skin feel and improving spreadability.
