Description

Marlophen Np 8 CAS NO 620168-37-8 is a high-purity nonylphenol ethoxylate surfactant, a key non-ionic surfactant in the alkylphenol ethoxylate (APEO) family. Its controlled ethylene oxide chain length provides a critical balance of hydrophilic and lipophilic properties, enabling superior wetting, emulsification, and detergent performance. This product is essential for formulators in the industrial cleaning, agrochemical, textile, and paint & coatings sectors seeking reliable and effective surface-active agents.

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a primary surfactant in heavy-duty degreasers, metal cleaners, and floor care formulations for its excellent oil and grease removal.
• Agrochemical Adjuvants: Used as an emulsifier, wetting, and spreading agent in pesticide and herbicide formulations to enhance foliar coverage and efficacy.
• Textile Processing: Employed in scouring, dyeing, and finishing baths as a detergent and leveling agent for fibers and fabrics.
• Paints & Coatings: Serves as a pigment wetting and dispersing agent, improving color development and stability in aqueous-based systems.
• Metalworking Fluids: Functions as an emulsifier in soluble oils and semi-synthetic coolants, providing lubrication and rust prevention.
• Pulp & Paper Industry: Used in de-inking processes and as a dispersant for pitch control.
