Peregal O-3 (fatty alcohol polyoxyethylene (3) ether, CAS No.: 68439-49-6) is a nonionic surfactant synthesized by condensing ethylene oxide with C12-14 natural fatty alcohol as the initiator. Due to its molecular structure where the lipophilic group dominates while possessing moderate hydrophilic properties, Peregal O-3 exhibits excellent water-in-oil (W/O) emulsifying ability, penetration wetting, and broad chemical compatibility in various industrial fields, making it an important choice for formulation engineers when designing efficient industrial auxiliaries.
In the textile and chemical fiber industry, Peregal O-3 runs through the entire process from spinning to weaving and then to dyeing and finishing—as a smoothing and antistatic component in synthetic fiber spinning oil, ensuring smooth operation of polyester, nylon, and polypropylene fibers during spinning and drawing; as a weaving oil to reduce yarn friction and breakage; as a leveling agent in printing and dyeing to promote uniform dye adsorption and prevent color spots and streaks; as a pretreatment penetrating agent to accelerate the penetration of alkali liquor and auxiliaries into the fiber interior, improving the efficiency of desizing, scouring, and mercerizing processes.
In the metalworking and industrial cleaning fields, Peregal O-3 is a key emulsifying and lubricating component in metalworking fluids such as cutting fluids, grinding fluids, and rolling oils. It can form stable O/W or W/O working emulsions, combining multiple functions of cooling, lubrication, and rust prevention, effectively extending the life of tools and molds. Meanwhile, its ability to rapidly penetrate oil layers makes it excellent in hard surface cleaning formulations such as metal pretreatment degreasing and machining cleaning. It is low-foaming and easy to rinse, offering economical overall usage costs.
In the pesticide and daily chemical fields, Peregal O-3 serves as a highly efficient emulsifier for pesticide emulsifiable concentrate (EC) formulations, enabling the active ingredient and solvent to form a homogeneous EC that automatically disperses into a stable emulsion upon dilution with water, ensuring uniform spraying and efficient absorption of the active ingredient. In cosmetic creams, lotions, and other oil-based systems, it acts as the primary emulsifier to prepare stable water-in-oil products. Additionally, its strong emulsifying and dispersing ability for non-polar liquids such as mineral oil, white oil, and alkane solvents makes it widely used in constructing emulsified systems for oil-based cleaners, water-based inks, adhesives, and other products.
