Peregal O-3 is a nonionic surfactant synthesized from natural C12-14 fatty alcohol as the initiator and condensed with ethylene oxide, featuring excellent water-in-oil (W/O) emulsifying ability and wetting/permeability.

Detailed Description

Peregal O-3, chemically named fatty alcohol polyoxyethylene (3) ether, also known as AEO-3, laureth-3, Emulsifier O-3, etc., CAS No. 68439-49-6. It belongs to nonionic surfactants, typically appearing as a colorless to slightly yellow liquid or paste with high active content. Its molecular structure has a low degree of ethylene oxide polymerization (EO number of 3), where the lipophilic group predominates while possessing moderate hydrophilic properties, making it particularly outstanding in water-in-oil (W/O) emulsion systems.

This product uses naturally derived C12-14 fatty alcohols as starting materials, manufactured through condensation with ethylene oxide, offering good biocompatibility and chemical stability. It remains active and stable across a wide range of acid-base conditions and hard water media, without precipitating or phase separating, and is broadly compatible with various anionic, cationic, and nonionic auxiliaries, facilitating compounded formulations.

Application Recommendations

With its exceptional W/O emulsifying power, outstanding wetting/permeability, and excellent chemical stability, Peregal O-3 is widely applied in the following fields:

  • Water-in-oil emulsifier: Used as the primary emulsifier in cosmetic creams, lubricants, pesticide emulsifiable concentrates, and other formulations with a high oil phase ratio.
  • Synthetic fiber spin finishes: Provides lubricity, cohesion, and antistatic properties for the processing of polyester, nylon, polypropylene, and other synthetic fibers, reducing filaments breakage and end breaks.
  • Industrial degreasing and hard surface cleaning: Rapidly penetrates oil layers in metal pretreatment and machining cleaning, enhancing oil removal efficiency and rinsing performance.
  • Textile dyeing and finishing auxiliaries: Functions as a leveling agent, penetrating agent, and finishing additive, promoting uniform dye uptake and effectively preventing dyeing defects such as uneven dyeing and spots.
  • Metalworking fluids: Acts as an emulsifier and lubricating component in cutting fluids, rolling oils, and other systems, combining cooling, lubrication, and rust prevention properties.
  • Pesticide emulsifiable concentrates and formulations: Serves as an emulsifier and penetration aid, improving the stability of pesticide emulsions and the spreading/absorption of the spray on targets.
