Peregal O-80 is a high-polymer non-ionic surfactant that combines emulsification, wetting, dispersion, and solubilization in one, with strong chemical resistance and excellent ecological safety.
Detailed Description
Peregal O-80 (Chemical name: C16-18 Alcohol Polyoxyethylene (80) Ether, CAS number: 68439-49-6) is a high-performance non-ionic surfactant produced by Guoli Chemical. It appears as a white to slightly yellow flake or waxy solid. Its molecular structure contains 80 ethylene oxide (EO) polymerization units, endowing the product with a high HLB value characteristic, making it particularly outstanding in constructing oil-in-water (O\/W) emulsion systems.
The core feature of this product is its "multi-function in one agent"—a single component can simultaneously perform four functions: emulsification, wetting, dispersion, and solubilization, significantly simplifying formulation design. In terms of chemical tolerance, Peregal O-80 maintains its activity under acidic, alkaline, and high-hardness water conditions, a performance advantage that many similar surfactants find difficult to achieve simultaneously, especially suitable for industrial scenarios with stringent process conditions.
From a safety perspective, Peregal O-80 is classified as practically non-toxic (rat oral LD50 > 5000 mg\/kg), non-irritating to skin and eyes, non-sensitizing, and its 28-day rapid biodegradation rate exceeds 60%, meeting current environmental sustainability requirements. It does not require hazardous goods management for storage and transportation.

Application Recommendations
With its multifunctional properties, Peregal O-80 is widely applicable in the following eight major fields:
- Textile Dyeing and Finishing: Used as a leveling agent, dispersant, and penetrating agent to ensure uniform dye uptake and deep fiber penetration.
- Daily Chemical Products: As an O\/W emulsifier in formulations of creams, lotions, shampoos, and body washes, imparting fine texture and good stability.
- Pesticide Formulations: Serves as an efficient emulsifier for emulsifiable concentrates, oil-in-water emulsions, suspension concentrates, etc., optimizing spreading and wetting of the spray solution and maintaining emulsion stability in hard water.
- Industrial Cleaning: As a wetting and solubilizing component, enhancing the detachment and suspension of oil and dirt, suitable for cleaning hard surfaces such as metal, glass, and plastic.
- Metalworking Fluids: Builds a stable emulsion system in water-based cutting and grinding fluids, carrying extreme pressure additives and extending the service life of the working fluid.
- Emulsion Polymerization: As a reactive emulsifier, reducing interfacial tension between monomer droplets and polymer particles, ensuring uniform nucleation and narrow particle size distribution control.
- Papermaking Industry: Core component of deinking agents, strongly wetting and dispersing ink particles to improve paper brightness.
- Leather Processing: Used in degreasing and fatliquoring processes, efficiently and gently removing natural fats from hides, imparting a soft and full hand feel.
Precautions
- Storage Conditions: Store in a cool, dry, and well-ventilated place, with ambient temperature maintained between 0°C and 40°C and relative humidity not exceeding 70%. Avoid extreme temperatures and drastic temperature changes.
- Operational Protection: Although classified as a non-hazardous substance, it is recommended to wear protective gloves and safety goggles during operation, ensure good ventilation in the workplace, and avoid generating and inhaling dust.
- Incompatible Substances: Keep away from strong oxidizers (e.g., peroxides, permanganates), strong acids, and strong bases.
- Spill Handling: Prevent spillage from entering sewers and water bodies. For small spills, absorb with inert absorbent material and collect in sealed containers.
- Shelf Life Management: Follow the first-in, first-out principle, use within the shelf life, and reseal the opened package immediately.
