Peregal O-3 is a low-polymerization degree nonionic surfactant initiated with natural C12-14 fatty alcohol, with core features including excellent water-in-oil (W/O) emulsifying power, outstanding wetting and penetrating properties, and exceptional chemical stability.

Detailed Description

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.

Summary of Core Properties

  • Excellent W/O emulsifying power: The lipophilic-group-dominated molecular structure stably disperses the aqueous phase into the oil phase, forming uniform, fine emulsions that do not separate during long-term storage.
  • Outstanding wetting and penetration: Rapidly reduces solid/liquid interfacial tension, promoting efficient spreading and deep penetration of liquids on substrate surfaces.
  • Exceptional chemical stability: Maintains stable activity over a wide range of acid-base conditions and in hard water media, without precipitation or phase separation.
  • Broad compatibility: Good compatibility with various anionic, cationic, and nonionic auxiliaries, facilitating formulation adjustment and optimization.
  • Cost-effective and efficient: Target effects can be achieved at low addition levels, offering a clear comprehensive cost advantage.

Application Recommendations

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.

Precautions

  • GHS hazard classification: Skin irritation (Category 2), serious eye irritation (Category 2A), hazardous to aquatic life (Category 3).
  • Wear nitrile rubber protective gloves, chemical safety goggles, and protective clothing during operation.
  • In case of accidental eye contact, immediately rinse with plenty of water for at least 15 minutes and seek medical attention; for skin contact, wash with soapy water for at least 15 minutes.
  • Store in a cool, dry, well-ventilated place. Keep containers tightly closed, away from heat sources and open flames, and avoid direct sunlight.
  • Do not discharge the product or packaging waste into water bodies. Waste disposal must be handled by a qualified professional agency.
