OPE-105 is a nonionic surfactant with octylphenol as the hydrophobic group, modified with 10.5 EO (ethylene oxide). With excellent emulsifying ability, outstanding wetting and penetrating performance, and a wide range of chemical resistance, it maintains stable interfacial activity under acidic, alkaline, and high-hardness water conditions, making it a key functional additive in multiple industrial fields.
This product can be used in combination with anionic, cationic, and other nonionic surfactants for synergistic enhancement, flexibly adapting to different process formulation needs. Its appearance ranges from colorless to light yellow transparent liquid or flowable paste, facilitating precise dosing and compounding.
| Industry | Process/Application | Function Description |
|---|---|---|
| Textile Industry | Scouring Penetrant | During desizing and scouring of cotton, linen, and other fibers, it rapidly penetrates and emulsifies waxes and oils, improving capillary effect and whiteness, creating a uniform foundation for subsequent bleaching and dyeing. |
| Leveling Agent | Promotes uniform dye uptake, prevents color spots and shading, and improves the first-time dyeing success rate. | |
| Metalworking | Cutting/Grinding/Stamping/Drawing Lubricants | Forms a high-strength lubricating film, reduces friction coefficient, carries away processing heat, and extends tool and mold life. |
| Rust Preventive Fluids | In water-based rust prevention systems, it adsorbs onto metal surfaces forming a protective layer, effectively isolating oxygen and moisture, suitable for inter-process and short-term storage rust prevention. | |
| Industrial Coatings | As a wetting and dispersing component in water-based or solvent-based coatings, it promotes pigment wetting, prevents floating and flooding, and improves film adhesion. | |
| Industrial Cleaning | Degreasing Cleaners | Rapidly removes mineral oils, animal and vegetable fats, and dirt from metal and plastic surfaces, suitable for spray, ultrasonic, and other cleaning processes at room temperature or with heating. |
| Pesticide Formulations | Emulsifiers (EC/EW) | Enables oil-soluble active ingredients to spontaneously disperse in water, forming stable emulsions, improving wetting and spreading of the active ingredient, and enhancing efficacy. |
| Dispersants (SC/WP) | Prevents pesticide particles from agglomerating and settling, maintains long-term storage stability of the formulation, and improves suspension rate after dilution. | |
| Leather Processing | Hide Degreasing Agent | Penetrates between leather fibers to emulsify natural fats, achieving uniform degreasing, improving leather softness and dyeing uniformity. |
| Paper Industry | Deinking Agent | In waste paper recycling deinking processes, it combines with ink particles, and through flotation or washing methods, separates ink from fiber surfaces and suspends it for removal, improving pulp whiteness. |
| Antistatic Agent | Coated or impregnated on synthetic fibers and plastic surfaces, it reduces surface resistance, accelerates static charge dissipation, and reduces dust attraction, static shock, and spark risks during production and use. |
The recommended concentration of OPE-105 in different processes is typically 0.1%–5.0% (based on total working fluid volume). The specific dosage should be determined experimentally based on oil phase type, water hardness, temperature, and formulation system. It is recommended to conduct compatibility and stability tests during the formulation development stage to fully utilize its synergistic effects with anionic, cationic, and other nonionic surfactants for optimal cost-effectiveness.
