The main ingredient of Peregal O-80 is C16-18 alcohol polyoxyethylene (80) ether, a nonionic fatty alcohol polyoxyethylene ether surfactant with a high degree of polymerization.

Detailed Description

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.

Application Recommendations

Based on the compositional characteristics of Peregal O-80 (C16-18 alcohol polyoxyethylene (80) ether: high HLB value, nonionic, saturated fatty alcohol structure), it is mainly suitable for the following scenarios:

  • O/W Emulsification Systems: Used in cosmetic creams, lotions, and hair care products to construct stable and fine oil-in-water emulsions. Recommended dosage is 2%~5% of the total formulation.
  • Textile Printing and Dyeing Auxiliaries: As a high-temperature leveling agent and penetrating agent, utilizing its alkali resistance, hard water tolerance, and excellent wetting properties to enhance the level dyeing rate. Dosage depends on the specific process.
  • Industrial Cleaning: As a solubilizing and wetting component to enhance detergency. Suggested addition of 1%~3% in hard surface cleaning formulations.
  • Emulsion Polymerization: As a reactive emulsifying dispersant to ensure uniform nucleation of latex particles and narrow particle size distribution control. Recommended dosage is 1%~4% of monomer weight.

Precautions

  • This product is a solid wax, which needs to be pre-melted or dissolved in warm water (recommended 40~50°C) before use. Avoid direct high-temperature heating to prevent localized overheating and discoloration.
  • It has strong hygroscopicity. After opening, the container should be sealed immediately and stored at a relative humidity not exceeding 70% and a temperature kept between 0°C and 40°C.
  • Store away from incompatible materials such as strong oxidants, strong acids, and strong alkalis.
  • This product is non-toxic, non-irritating, and readily biodegradable. However, it is still recommended to wear protective gloves and goggles during operation and follow standard industrial hygiene practices.
