Peregal O-80 is a high-polymerization-degree nonionic fatty alcohol polyoxyethylene ether surfactant that integrates emulsifying, wetting, dispersing, and solubilizing capabilities, widely used in industries such as textiles, daily chemicals, agrochemicals, and industrial cleaning.

Detailed Description

Peregal O-80 (CAS No.: 68439-49-6), with the full chemical name of C16-18 Alcohol Polyoxyethylene (80) Ether, is a high-performance nonionic surfactant produced by Haian Guoli Chemical Co., Ltd. Its molecular weight is approximately 3800, and it appears as a white to slightly yellow flake or waxy solid. The product has an effective content of ≥99%, exhibiting extremely high purity and demonstrating excellent stability and reliability in industrial applications.

As a surfactant with a high HLB value (18.5), the core advantage of Peregal O-80 lies in its outstanding oil-in-water (O/W) emulsifying ability, capable of forming long-term stable emulsion systems. Additionally, it possesses excellent wetting and dispersing properties, effectively inhibiting the re-agglomeration and sedimentation of solid particles. Its significant solubilizing effect greatly enhances the compatibility and transparency of hydrophobic substances in water-based formulations. Furthermore, this product exhibits strong tolerance to acids, alkalis, and high-hardness water environments, maintaining its activity even under harsh chemical conditions, making it an ideal choice for numerous industrial formulations.

From a safety perspective, Peregal O-80 is classified as a non-hazardous substance. Toxicological data show that its acute oral LD50 > 5000 mg/kg, indicating it is practically non-toxic; it is non-irritating to skin and eyes, non-sensitizing, and non-mutagenic. Environmentally, the product achieves a 28-day rapid biodegradation rate exceeding 60%, meeting the requirements for readily biodegradable classification. It has low toxicity to aquatic organisms, is not classified as PBT or vPvB substances, and complies with strict current environmental sustainability requirements.

Application Recommendations

With its excellent emulsifying, wetting, dispersing, and solubilizing properties, Peregal O-80 is widely used in eight major industries:

  • Textile Dyeing and Finishing: Used as a leveling agent, dispersant, and penetrant, suitable for pretreatment, dyeing, and finishing of various fibers and their blends, effectively improving dye uptake uniformity and fabric hand feel. Recommended dosage depends on process requirements, typically 0.5%~3% of the working liquor.
  • Daily Chemical Products: Acts as an O/W emulsifier and stabilizer in formulations such as creams, lotions, shampoos, and body washes, leveraging its high HLB value to build stable emulsion systems and provide a delicate texture. Recommended dosage is 1%~5% of the total formulation.
  • Agrochemical Formulations: Serves as a highly effective emulsifier for formulations such as emulsifiable concentrates, emulsion in water, and suspension concentrates, significantly enhancing emulsification dispersion performance and field dilution stability, especially in hard water environments.
  • Industrial Cleaning: Acts as a cleaning aid to enhance the detachment and suspension of oils and dirt, suitable for hard surface cleaning of metals, glass, and plastics.
  • Metalworking Fluids: Provides synergistic emulsifying and lubricating effects in water-based cutting fluids and grinding fluids, helping to form stable emulsions, improving cooling and lubrication, and reducing tool wear.
  • Emulsion Polymerization: Functions as a reactive emulsifier, effectively reducing interfacial tension between monomer droplets and polymer particles, ensuring uniform nucleation and narrow particle size distribution control.
  • Paper Industry: Core component of deinking agents, strongly wetting and dispersing ink particles to enhance paper brightness.
  • Leather Processing: Used in degreasing processes to remove natural fats from raw hides, and can also be a component of fatliquoring agents to impart softness and fullness to leather.

Precautions

  • Storage Conditions: Store in a cool, dry, well-ventilated warehouse, maintaining ambient temperature between 0°C and 40°C and relative humidity no higher than 70%. Avoid extreme temperatures and sudden temperature changes. The product may soften at high temperatures and harden at low temperatures.
  • Hygroscopicity: This product is hygroscopic. After use, immediately re-seal the container to avoid prolonged exposure to humid air.
  • Compatibility Note: Keep away from incompatible substances such as strong oxidizers (e.g., peroxides, permanganates), strong acids, and strong alkalis.
  • Safe Handling: Although it is non-hazardous and non-irritating, it is still recommended to wear protective gloves and goggles during operation, and maintain good ventilation in the workplace. Do not eat, drink, or smoke during work.
