OP-10 is widely used as a nonionic surfactant in various industrial and laboratory applications. It is commonly employed as an emulsifier in the formulation of pesticides, helping active ingredients disperse evenly in water and adhere to plant surfaces. In the textile industry, OP-10 serves as a wetting, cleaning, and dyeing agent due to its ability to reduce surface tension and stabilize emulsions.

It is also used in metal processing as a degreasing agent to remove oils and contaminants from metal surfaces before coating or painting. In cleaning products, OP-10 enhances the removal of grease and dirt by improving solubilization and suspension of oily substances in water. Additionally, in the petroleum industry, it aids in removing oil stains and contaminants in oil production systems.

OP-10 finds application in the synthesis of polymers and resins as an emulsifier and dispersing agent, particularly in emulsion polymerization processes. Its stability over a wide pH range and compatibility with other chemical agents make it suitable for use in detergents, biocides, and industrial cleaners, including laundry detergents, dishwashing liquids, and general cleaning products.
