Peregal O-80 is a versatile nonionic surfactant widely used in eight major industries including textile dyeing and finishing, daily chemicals, pesticides, industrial cleaning, metalworking fluids, emulsion polymerization, papermaking, and leather processing, playing a core role in key processes such as leveling, emulsification, dispersion, wetting, and solubilization.

Detailed Description

Peregal O-80 (Chemical name: C16-18 alcohol polyoxyethylene (80) ether, CAS No.: 68439-49-6) is a high-degree polymerized fatty alcohol polyoxyethylene ether nonionic surfactant. With its excellent core properties of emulsification, wetting, dispersion, and solubilization, as well as strong tolerance to acid, alkali, and high-hardness water environments, Peregal O-80 has become an irreplaceable formulation component in many industrial fields.

In emulsification applications, Peregal O-80 is specifically used to construct long-term stable oil-in-water (O/W) emulsion systems. Its high HLB value enables uniform dispersion of hydrophobic substances in the aqueous phase. In terms of dispersion and wetting, it effectively inhibits re-agglomeration and sedimentation of solid particles, significantly improving the uniformity and stability of the formulation. Additionally, its notable solubilization effect greatly enhances the compatibility and transparency of hydrophobic substances in water-based formulations, providing strong support for the performance of end products.

From a safety and environmental perspective, Peregal O-80 is a non-hazardous substance with an acute oral LD50 greater than 5000 mg/kg (practically non-toxic), non-irritating to skin and eyes, and a 28-day rapid biodegradation rate of over 60%, making it readily biodegradable. It meets current environmental sustainability requirements and offers a broad safety margin for industrial applications.

Overview of Eight Industries and Process Applications

Application Industry Specific Process/Use Function Description
Textile Dyeing and Finishing Leveling agent, Dispersant, Penetrant Used in pretreatment, dyeing, and finishing processes for various fibers and their blends, improving dye uniformity and fabric hand feel, ensuring deep fiber penetration
Daily Chemical Products O/W Emulsifier and Stabilizer Builds stable oil-in-water emulsion systems in formulations such as creams, lotions, shampoos, and body washes, imparting a fine texture and good formulation stability
Pesticide Formulations Emulsifier for Emulsifiable Concentrates, Aqueous Emulsions, Suspension Concentrates Uniformly disperses active ingredients in aqueous or oil phases, improving emulsifying dispersion performance and dilution stability in the field, optimizing spray adhesion and wetting effects
Industrial Cleaning Wetting Agent, Solubilizer, Detergent Aid Used in hard surface cleaning formulations for metals, glass, and plastics, enhancing the removal and suspension of oil and dirt, improving cleaning efficiency
Metalworking Fluids Emulsifier for Water-based Cutting Fluids and Grinding Fluids Builds a stable emulsion system, effectively carrying extreme pressure additives, improving cooling and lubrication, reducing tool wear and workpiece corrosion, extending fluid life
Emulsion Polymerization High HLB Emulsifying Dispersant Reduces interfacial tension between monomer droplets and polymer particles, ensuring smooth polymerization and obtaining uniform latex particle size
Papermaking Industry Core Component of Deinking Agent, Fiber Rewetting Agent Promotes detachment and dispersion of ink from fiber surfaces, enhances fiber rewetting properties, facilitating subsequent pulp treatment and improving paper whiteness
Leather Processing Component of Degreasing Agent and Fatliquoring Agent Efficiently and gently removes natural fats and dirt from raw hides, participates in fatliquoring and filling processes, imparting a soft and full hand feel to leather

Application Suggestions

Peregal O-80 can be used flexibly in formulations, typically by direct addition. Based on specific process requirements, the following directions are recommended:

  • Emulsification Applications: Utilize its high HLB value as a primary or auxiliary emulsifier for O/W emulsion systems. It is recommended to combine with other low-HLB emulsifiers to broaden the stability range of the emulsion system.
  • Dispersion and Leveling: In textile dyeing and finishing processes, it can be used synergistically with anionic or cationic auxiliaries to improve leveling effect and dye bath stability.
  • Cleaning Formulations: As a nonionic surfactant component, compounding with anionic surfactants can produce synergistic effects, enhancing detergency and hard water resistance.
  • Storage and Pretreatment: The product is a white to slightly yellow flake or waxy solid. If accelerated dissolution is needed before use, it is recommended to pre-dissolve in warm water before feeding. The storage environment should be maintained at 0°C to 40°C, with relative humidity not exceeding 70%.

Precautions

  • Keep away from strong oxidizers, strong acids, strong bases, and other incompatible substances during storage. Keep the container tightly closed.
  • It is recommended to wear protective gloves and goggles during operation, ensuring good ventilation in the workplace.
  • Do not discharge the product into drains or environmental waters. Waste disposal should comply with local regulations, prioritizing recycling or handing over to authorized chemical incineration facilities.
  • Avoid extreme temperatures and drastic temperature changes. The product may soften at high temperatures and harden at low temperatures, which are normal physical changes and do not affect product quality.
