Peregal O-80 (chemical name: C16-18 fatty alcohol polyoxyethylene (80) ether, CAS number: 68439-49-6) belongs to the high-polymerization-degree fatty alcohol polyoxyethylene ether nonionic surfactants. Its molecular structure contains 80 oxyethylene (EO) units, giving it extremely high hydrophilicity and HLB value, making it an ideal choice for constructing oil-in-water (O/W) emulsion systems. The product appears as a white to slightly yellow flake or waxy solid, maintaining stable activity under harsh chemical conditions such as acids, alkalis, and high-hardness water.
This product integrates four major functions: emulsification, wetting, dispersion, and solubilization. It can effectively reduce interfacial tension, inhibit re-aggregation of solid particles, and enhance the compatibility and transparency of hydrophobic substances in aqueous formulations. With its excellent versatility, Peregal O-80 has become an indispensable core additive component in many industrial formulations.
In terms of safety and environmental protection, Peregal O-80 is a non-hazardous substance with an acute oral toxicity LD50 > 5000 mg/kg (practically non-toxic grade). It is non-irritating to skin and eyes, non-sensitizing, and readily biodegradable (OECD 301B test shows >60% degradation in 28 days), meeting the requirements of modern industry for environmental sustainability.
| Industry Sector | Application Process/Step | Function/Role |
|---|---|---|
| Textile Printing and Dyeing | Pretreatment, dyeing, finishing processes | Used as leveling agent, dispersant, and penetrant to ensure uniform dye uptake, improve fabric hand feel, and enhance fiber penetration depth |
| Daily Chemical Products | Formulations of creams, lotions, shampoos, body washes, etc. | O/W type emulsifier and stabilizer, building a stable emulsification system, imparting a fine texture and good formulation stability to the product |
| Pesticide Formulations | Emulsifiable concentrates, water emulsions, suspension concentrates, etc. | Highly efficient emulsification synergist, uniformly dispersing the technical material in the aqueous or oil phase, improving dilution stability in the field and the spreading and wetting properties of the spray liquid |

| Metalworking Fluids | Formulations of water-based cutting fluids, grinding fluids | Building a stable emulsification system, carrying extreme pressure additives, improving cooling and lubrication effects, extending working fluid life, and reducing tool wear |
| Emulsion Polymerization | Polymerization process for latex preparation | Reactive emulsifying dispersant, reducing interfacial tension between monomers and polymer particles, ensuring uniform nucleation of latex particles and control of narrow particle size distribution |
| Papermaking Industry | Waste paper deinking process | Core component of deinking agent, strongly wetting and dispersing ink particles, promoting fiber rewetting, improving paper brightness and quality |
| Leather Processing | Degreasing process and fatliquoring/filling | Efficiently and gently removing natural fats and dirt from raw hides, as a fatliquoring component imparting soft and full hand feel to leather |
Formulation Design: The high HLB value characteristic of Peregal O-80 makes it particularly suitable as the primary emulsifier or co-emulsifier in O/W emulsion systems. In formulations requiring strong hydrophilicity, it is recommended to combine it with low HLB value emulsifiers to achieve a broader emulsification range and better emulsion stability.
Addition Process: This product is a flake or waxy solid. It is recommended to pre-dissolve it in warm water under stirring or directly add it to the hot phase for dissolution and dispersion. The material may soften at high temperatures and harden at low temperatures. Appropriate feeding methods should be selected according to the actual process temperature during operation.
Recommended Dosage: The specific dosage varies depending on the application scenario and target performance requirements. As an emulsifier, the typical dosage is 1%-5% of the total formulation weight; as a wetting and dispersing aid, the dosage is generally 0.5%-3%. It is recommended to determine the optimal addition ratio through orthogonal experiments.
