The full chemical name of Peregal O-80 is C16-18 alcohol polyoxyethylene (80) ether (English name: Polyoxyethylene (80) fatty alcohol ether), belonging to the class of fatty alcohol polyoxyethylene ether nonionic surfactants. Its molecular structure consists of two parts: the hydrophobic end being a C16-C18 long-chain fatty alcohol (naturally derived saturated fatty alcohol), and the hydrophilic end being a polyoxyethylene chain segment with an average degree of polymerization of about 80 (i.e., ethylene oxide addition number n≈80). This structure endows the product with a high HLB value (approx. 18.5) and excellent water solubility, enabling it to form clear and transparent solutions in water.
According to the Guoli Chemical product database, the active ingredient content of Peregal O-80 is ≥99%, free alcohol content ≤3%, moisture ≤1.0%, indicating extremely high purity. Appearance is a white to slightly yellow flake or waxy solid with a melting point between 45~55°C. The molecular weight is about 3800, and the CAS number is 68439-49-6. The product maintains stable chemical activity under acid, alkali, and high-hardness water conditions, and is readily biodegradable, with a 28-day rapid biodegradation rate exceeding 60%.
From a compositional perspective, in the name Peregal O-80, "O" represents Oleyl or Oxyethylene, and "80" represents the degree of polymerization of ethylene oxide. Such a high EO addition number endows the product with multiple functions including emulsification, wetting, dispersion, and solubilization, specifically designed for constructing stable long-term oil-in-water (O/W) emulsion systems, widely used in textile printing and dyeing, household chemicals, pesticides, industrial cleaning, and other fields.
