Peregal O-80 is a high-performance nonionic surfactant with the chemical name C16-18 fatty alcohol polyoxyethylene (80) ether, integrating emulsification, wetting, dispersion, and solubilization in one. It is widely used in textiles, daily chemicals, pesticides, industrial cleaning, and many other industries.

Detailed Description

Peregal O-80 (CAS No.: 68439-49-6) is a nonionic surfactant produced by Haian Guoli Chemical Co., Ltd. It appears as a white to slightly yellow flake or waxy solid. As a high-degree polymerized fatty alcohol polyoxyethylene ether, the polyoxyethylene chain segments in its molecular structure endow the product with excellent hydrophilicity and interfacial activity.

This product has four core performance advantages: Excellent emulsifying efficiency, specifically used to build long-term stable oil-in-water (O/W) emulsion systems; Superior wetting and dispersing ability, effectively inhibiting re-agglomeration and sedimentation of solid particles; Significant solubilization effect, greatly enhancing the compatibility and transparency of hydrophobic substances in water-based formulations; Strong tolerance to chemical environments, maintaining activity under acidic, alkaline, and high-hardness water conditions. Additionally, Peregal O-80 has good ecological properties, being readily biodegradable, non-irritating to skin and eyes, with an acute oral toxicity LD50 greater than 5000 mg/kg, classified as practically non-toxic.

Main Uses (Eight Application Fields)

1. Textile Dyeing and Finishing: Used as a leveling agent, dispersant, and penetrant. With its excellent wetting and penetrating ability, it ensures uniform dye uptake and deep dyeing effect on fabrics, suitable for pretreatment, dyeing, and finishing of various fibers and their blends.

2. Daily Chemical Products and Cosmetics: As an O/W emulsifier and stabilizer, leveraging its high HLB value, it builds stable oil-in-water emulsion systems in creams, lotions, shampoos, and shower gels, imparting fine texture and good formulation stability.

3. Pesticide Formulations: Serves as a highly efficient emulsifier in emulsifiable concentrates, emulsion concentrates, and suspension concentrates, uniformly dispersing active ingredients in water or oil phases, significantly improving the emulsifying dispersion performance and field dilution stability, maintaining emulsion stability even in hard water.

4. Industrial Cleaning: Used as a cleaning additive in hard surface cleaning formulations for metals, glass, and plastics. Its excellent detergency, wetting, and penetrating properties enhance the removal and suspension of oils and dirt.

5. Metalworking Fluids: In water-based cutting fluids and grinding fluids, it performs an emulsifying and lubricating synergistic effect, helping to form stable emulsions, effectively carrying extreme pressure additives, improving cooling and lubrication, and reducing tool wear and workpiece corrosion.

6. Emulsion Polymerization: As a reactive emulsifying dispersant, it effectively reduces interfacial tension between monomer droplets and polymer particles, ensuring smooth polymerization and producing latex products with uniform particle size.

7. Paper Industry: In waste paper deinking processes, it serves as a key component of deinking agents, promoting ink detachment and dispersion from fiber surfaces while enhancing fiber rewetting, facilitating subsequent pulp treatment and improving paper brightness.

8. Leather Processing: Used in degreasing processes to efficiently and gently remove natural fats and dirt from raw hides. It can also be incorporated as a component of fatliquoring agents to impart soft and full hand feel to leather.

Precautions

  • Store in a cool, dry, well-ventilated warehouse. Maintain ambient temperature between 0°C and 40°C, avoiding extreme temperatures and rapid temperature changes.
  • Keep packaging containers tightly sealed. Reseal immediately after opening. Keep away from strong oxidizers, strong acids, strong bases, and other incompatible substances.
  • It is recommended to wear nitrile rubber gloves and chemical safety goggles during operation. Ensure good ventilation in the workplace.
  • Although the product is of very low toxicity, avoid direct contact with eyes, skin, and clothing. Do not eat, drink, or smoke during work.
  • Dispose of waste in accordance with local regulations. Do not discharge into sewers or environmental waters. Prioritize recycling and reuse or send to authorized chemical incineration facilities.
  • Follow the FIFO (First In, First Out) inventory management principle and use within the shelf life.
