OP-10 (Octylphenol Polyoxyethylene Ether) is a high-performance nonionic surfactant, renowned for its excellent emulsifying, wetting, penetrating, and detergency properties, widely used in various fields such as industrial cleaning, textiles, pesticides, coatings, and more.
Detailed Description
OP-10, with the chemical name Octylphenol Polyoxyethylene Ether (CAS No.: 9036-19-5), is produced by Guoli Chemical. It is a nonionic surfactant, typically appearing as a colorless to pale yellow transparent liquid. Its molecular structure contains 10 ethylene oxide (EO) chain segments, which impart hydrophilicity, enabling it to be easily soluble in water while maintaining excellent chemical stability over a wide pH range, resisting hard water, and exhibiting good compatibility with various additives.
As a classic high-efficiency surfactant, the core value of OP-10 lies in its diverse functionality. It effectively reduces oil-water interfacial tension, forming stable emulsions, making it an excellent emulsifier; simultaneously, it significantly lowers liquid surface tension (about 30 mN/m for a 1% aqueous solution at 25°C), achieving rapid wetting and penetration; additionally, it has good suspension, dispersion, and removal capabilities for dirt particles, acting as an efficient detergent and dispersant.

Application Recommendations
OP-10 has extremely wide applications and can be used in various formulations according to different industry needs:
- Industrial and Household Cleaners: As a core surfactant in metal degreasers and hard surface cleaners, it rapidly wets and emulsifies oils and fats, significantly enhancing detergency.
- Textile Dyeing and Finishing Auxiliaries: It can serve as an efficient penetrating agent and leveling agent, helping dye liquor penetrate evenly into fibers, improving dyeing quality and processing efficiency.
- Pesticide Emulsifiers: Used in emulsifiable concentrates and emulsion concentrates, it uniformly disperses pesticide active ingredients, enhancing the wetting, spreading, and penetration ability of the spray liquid on plant surfaces.
- Waterborne Coatings and Inks: As a wetting and dispersing agent for pigments and fillers, and as an emulsifier for emulsion polymerization, it improves the storage stability of the system and prevents pigment settling.
- Other Applications: It can also be used in leather degreasing, paper deinking, crude oil demulsification, and as a component of metalworking fluids, providing lubrication and cleaning functions.
Precautions
- Safety Risks: This product is harmful if swallowed (H302), causes skin irritation (H315), causes serious eye irritation (H319), and is harmful to aquatic life with long-lasting effects (H412). When handling, be sure to wear appropriate protective clothing, nitrile rubber gloves, and chemical safety goggles.
- Handling and Storage: Use in a well-ventilated area, avoid inhaling vapors or mists. Store in a cool, dry, well-ventilated place, with an ambient temperature recommended between 5°C and 40°C. Immediately seal the container after use to prevent moisture absorption and contamination.
- Emergency Measures: In case of contact with eyes, rinse immediately with plenty of water for at least 20 minutes and seek medical attention; for skin contact, wash thoroughly with soap and water. In the event of a spill, collect with inert absorbent material (e.g., sand), and do not flush into drains.
