OPE-105 (Octylphenol Ethoxylate) is widely used in six major industries: textiles, metal processing, industrial cleaning, pesticide formulations, leather processing, and papermaking. It is an indispensable nonionic surfactant in many industrial formulations.

Detailed Description

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.

Application Industries and Processes Overview

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.

Application Recommendations

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.

Precautions

  • Safety Risks: Harmful if swallowed (H302), causes skin irritation (H315), causes serious eye damage (H318), and is toxic to aquatic life (H411). Protective gloves, safety glasses, and protective clothing must be worn during operation.
  • Use Environment: It is recommended to use in well-ventilated areas. No eating, drinking, or smoking is allowed in the workplace. Thoroughly wash exposed areas after operation.
  • Storage Requirements: Store in a cool, dry, and well-ventilated place. The temperature is recommended to be maintained between 0°C and 30°C. Keep containers tightly closed, away from food, feed, and strong oxidizers.
  • Environmental Disposal: Do not discharge into water bodies or the environment. Waste liquid and containers must be disposed of as hazardous waste by professional agencies.
  • First Aid Tips: In case of eye contact, rinse immediately with plenty of water for at least 15 minutes and seek medical attention. For skin contact, wash with soap and plenty of water. If swallowed, do NOT induce vomiting and seek medical attention immediately.
