Peregal O-3 (fatty alcohol polyoxyethylene (3) ether) is a nonionic surfactant synthesized by condensing natural C12-14 fatty alcohols with ethylene oxide. Its molecular structure is dominated by lipophilic groups while also possessing moderate hydrophilicity, granting it excellent water-in-oil (W/O) emulsifying ability and outstanding wetting and penetration properties. Thanks to its low polymerization degree (3 EO units), Peregal O-3 acts as an efficient and stable functional additive in various industrial formulations and is widely compatible with anionic, cationic, and other nonionic auxiliaries, making it a core functional raw material across multiple industries and processes.
In terms of industry coverage, Peregal O-3 has the most diverse applications in the textile industry, spanning the entire process from spinning, weaving, pretreatment, dyeing to finishing. In cosmetics and personal care, it is a key emulsifier for oily formulations such as creams and lotions. In metal processing and industrial cleaning, its synergistic effects of degreasing, lubrication, and emulsification are significant. In pesticide formulations, it ensures the stability of emulsifiable concentrates and the spreading and absorption of the spray liquid on targets.
Synthetic Fiber Spinning Oil: During the spinning of synthetic fibers such as polyester, nylon, and polypropylene, Peregal O-3 is used as a smoothing agent and antistatic component to reduce fiber friction, prevent filament breakage, impart good spinnability and hand feel, and ensure efficient operation of the spinning and drawing processes.
Weaving Oil: As a yarn treatment oil in the weaving process, it reduces the friction coefficient of the yarn on the loom, effectively minimizing breaks and improving weaving efficiency and fabric surface quality.
Textile Dyeing Leveling Agent: During dyeing, it helps disperse dyes uniformly and slowly adsorb onto fibers, preventing uneven dyeing such as color spots and streaks, significantly improving levelness and dyeing reproducibility.
Penetrating Agent (Pretreatment): Used in pretreatment processes such as desizing, scouring, and mercerizing, its excellent wetting and penetration capabilities accelerate the penetration of alkali or auxiliaries into the fiber interior, enhancing treatment effectiveness and efficiency.
Finishing Auxiliary: Improves fabric appearance and hand feel as a functional component in soft finishing.
W/O Cream and Lotion Preparation: Peregal O-3 stably disperses the water phase into the oil phase, forming a uniform and fine emulsion that does not separate during long-term storage. It is especially suitable for formulations with a high oil phase ratio, such as creams and lotions.
Metalworking Fluids (Cutting Fluids, Grinding Fluids, Rolling Oils, etc.): As an important emulsifier and lubricant component, it forms stable O/W or W/O working emulsions that provide cooling, lubrication, and rust prevention, extending the service life of tools and molds.
Industrial Degreasing and Hard Surface Cleaning: In metal pretreatment and machining cleaning, it rapidly penetrates oil layers, effectively removing stubborn contaminants such as mineral oil and rust-preventive oils, offering high degreasing efficiency with low foam and easy rinsing.
Pesticide Emulsifiable Concentrate (EC) Emulsifier: It forms a homogeneous emulsifiable concentrate with the pesticide active ingredient and organic solvent. Upon dilution with water, it automatically disperses into a stable emulsion, ensuring uniform spraying of the active ingredient. It also acts as a penetration adjuvant, enhancing the spreading and absorption of the spray liquid on plant leaves and target surfaces, thereby improving efficacy.
Emulsification and Dispersion of Mineral Oils and Non-polar Solvents: It has strong emulsifying and dispersing capabilities for non-polar liquids such as mineral oils, white oils, and alkane solvents, commonly used in formulating emulsified systems for oil-based cleaners, water-based inks, and adhesives.
Lubricant Emulsion Systems: In industrial lubricant formulations, it provides stable emulsification, ensuring uniformity and performance of the oil system.
