OP-4.5(X-45)
Jienuo
Emulsifier OP - 4.5 (Alkylphenol polyoxyethylene (4.5) ether) is a non - ionic surfactant. It excels in emulsifying, wetting, dispersing, and detergency. Widely used in textile, metalworking, and as an emulsifier in polymer industries.
Product Advantage
Excellent Emulsifying Performance: Emulsifier OP - 4.5 can efficiently emulsify various oil - water systems. In tests, it achieves stable emulsification of mineral oil in water with an emulsification time as short as 30 seconds, and the emulsion remains stable for over 72 hours without stratification.
Strong Wetting and Dispersing Abilities: It exhibits remarkable wetting on low - energy surfaces like polyester, reducing the contact angle from 75° to 30° within 10 seconds. Also, it can disperse solid particles with a particle size down to 5μm, ensuring uniform distribution in the system.
Good Compatibility: Compatible with anionic, cationic, and other non - ionic surfactants. When compounded with anionic surfactants, the detergency can be increased by 30% compared to using a single component.
Wide pH Range Adaptability: Works effectively in a pH range of 5.0 - 7.0. Even in slightly acidic or neutral environments, its performance remains stable without significant loss of activity.

Product Uses
Textile Industry: Serves as a dyeing and finishing auxiliary, improving the uniformity of dyeing for cationic dyes on fabrics and enhancing color fastness by 2 - 3 grades. Also used in textile printing to ensure even ink distribution.
Metalworking Field: Acts as a cleaning agent for metal parts, effectively removing grease and dirt. In metal cutting fluids, it helps to form a stable emulsion, providing lubrication and cooling effects.
Polymer Industry: Used as an emulsifier in the polymerization of polyvinyl acetate, enabling smooth emulsion polymerization and obtaining latex particles with a uniform size distribution (200 - 300nm).
For usage, add Emulsifier OP - 4.5 to the system under stirring at room temperature. Adjust the dosage based on specific applications, typically 0.5 - 5% of the total formulation. Ensure uniform mixing for optimal performance.
