Peregal O-3 (Fatty alcohol polyoxyethylene (3) ether, CAS No.: 68439-49-6) is a nonionic surfactant containing only three ethylene oxide (EO) units in its molecule. The lipophilic groups dominate, giving it strong lipophilic tendencies and moderate hydrophilic characteristics. This structural feature determines its ability to stably disperse the aqueous phase into the oil phase in water-in-oil (W/O) systems, forming uniform, fine emulsions that do not separate during long-term storage, making it the preferred emulsifier for various oil-based formulation systems.
In appearance, Peregal O-3 is typically a colorless to pale yellow liquid or paste with high active content. Thanks to the appropriate EO chain length in the molecule, it maintains stable activity over a wide range of acid-base conditions and in hard water media, without precipitation or phase separation, adapting to various harsh industrial environments from acidic to alkaline. It also exhibits good compatibility with anionic, cationic, and nonionic auxiliaries, facilitating synergistic effects in compound formulations.
Additionally, Peregal O-3 is highly cost-effective—target emulsifying, penetrating, or wetting effects can be achieved at very low addition levels, offering a clear comprehensive cost advantage. It is widely used in textile printing and dyeing, industrial cleaning, metal processing, pesticide formulations, and chemical fiber finishes.

The core application direction of Peregal O-3 revolves around its strong lipophilic properties: as a primary W/O emulsifier in cosmetic creams, lubricating oils, pesticide emulsifiable concentrates, and other oil-based systems; as a smoothing and antistatic component in chemical fiber spinning finishes; as an efficient penetrating degreasing component in industrial degreasing cleaners; as a leveling agent in textile printing and dyeing to promote uniform dye uptake; and as an emulsifying and dispersing auxiliary in metalworking fluids and pesticide formulations.
