OP-7
Jienuo
Emulsifier OP - 7, also known as Alkylphenol polyoxyethylene (7) ether, is a non - ionic surfactant. It excels in emulsifying, wetting, and dispersing. Widely used in industries like textiles, chemicals, and detergents, it enhances product performance effectively.
Product Advantage
Excellent Emulsifying Ability: Emulsifier OP - 7 shows remarkable emulsifying performance. In relevant tests, it can effectively emulsify various oils and water - based systems, with an emulsification efficiency that is 20% higher than some ordinary non - ionic surfactants.
Strong Adaptability to Hard Water: It works well in hard water environments. Even in water with a hardness of up to 500 mg/L (as CaCO₃), it maintains stable emulsifying and wetting functions, which is very suitable for areas with poor water quality.
Good Compatibility: It has good compatibility with anionic, cationic, and other non - ionic surfactants. When compounded with them, it can synergistically enhance the overall performance of the formulation, expanding the application range of products.
Stable Chemical Properties: It has stable chemical properties and can withstand a wide range of pH values (5.0 - 7.0, as shown in technical indicators) and temperatures, ensuring consistent performance in different production processes.

Product Uses
Textile Industry: It is used as a scouring agent and emulsifier in textile processing. It helps remove impurities from fibers and ensures uniform dyeing by emulsifying dye auxiliaries.
Metal Processing: As a cleaning agent in metal processing, it can effectively remove oil and dirt from metal surfaces, and also serves as an emulsifier in cutting fluid to keep the fluid stable.
Detergent Field: Added to detergents, it enhances the cleaning ability, especially in hard water, to remove stains on clothes or utensils more effectively.
Chemical Production: It acts as an emulsifier and dispersant in the production of some chemical products, promoting the uniform mixing of reactants and improving product quality.
For usage, simply add Emulsifier OP - 7 to the formulation system under normal temperature. Stir evenly to ensure full mixing. Adjust the dosage based on specific application needs, typically 1 - 10% of the total formulation.
FAQ
Q: Is Emulsifier OP - 7 toxic?
