OP-10 (Octylphenol Polyoxyethylene Ether) is a flagship nonionic surfactant of Guoli Chemical, appearing as a colorless to light yellow transparent liquid or paste. With its excellent emulsifying, wetting, penetrating, and dispersing properties, OP-10 has become an indispensable core additive in numerous industrial formulations. It has high chemical stability, maintaining stable performance over a wide pH range, is resistant to hard water, and has excellent compatibility with various anionic, cationic, and other nonionic additives.
In the field of industrial and household cleaning, OP-10 is widely used in formulations such as metal degreasers and hard surface cleaners, quickly wetting and emulsifying oil stains, effectively suspending and dispersing dirt particles, and providing both detergency and anti-redeposition functions. In the textile printing and dyeing industry, it serves as a penetrating agent, leveling agent, and wetting agent, helping dye liquor uniformly penetrate fibers, significantly improving dyeing quality and processing efficiency.
Furthermore, OP-10 is used as an emulsifier for emulsifiable concentrates (EC) and oil-in-water emulsions (EW) in pesticide formulations, ensuring uniform dispersion of active ingredients and enhancing formulation stability and adhesion. In water-based coatings and inks, it acts as a wetting and dispersing agent and an emulsion polymerization emulsifier, improving pigment dispersion. In leather processing, it is used for degreasing; in papermaking, for felt washing and waste paper deinking; in oil field exploitation, for crude oil demulsification and acidizing additives; in metalworking fluids, it provides lubrication, cooling, and cleaning functions.

The recommended dosage of OP-10 in actual formulations varies depending on the application: as the primary surfactant in cleaner formulations, the recommended addition amount is 3%~10%; in pesticide emulsifiers, it typically accounts for 5%~15% of the total formulation; in textile leveling agents, it is generally 1~3 g/L of working solution; as a wetting and dispersing agent in water-based coatings, the recommended addition amount is 0.5%~2% of the pigment weight. The specific dosage should be optimized through experiments based on the actual system and process conditions.
OP-10 can be compounded with nonionic, anionic, and cationic surfactants as well as various additives. When compounding, it is recommended to first conduct small-scale tests to verify compatibility stability and synergistic effects. For applications requiring low foam, it can be used in combination with low-foaming surfactants or with a defoamer.
