Description

Np9 CAS NO 98113-10-1 is a high-purity nonylphenol ethoxylate surfactant, a key component in the formulation of industrial and institutional cleaning products. Its precise ethoxylation chain length provides an optimal balance of detergency, wetting, and emulsification properties, making it a versatile and effective raw material. This product is essential for manufacturers in the agrochemical, textile, metalworking, and industrial cleaning sectors who require reliable performance and consistent quality in their formulations.

Application

• Industrial & Institutional (I&I) Cleaners: A primary surfactant in heavy-duty degreasers, floor cleaners, and detergent formulations for its excellent grease-cutting and soil removal capabilities.
• Agrochemical Formulations: Used as an emulsifier and wetting agent in pesticide and herbicide concentrates to enhance spray coverage and active ingredient dispersion.
• Textile Processing: Employed in scouring, dyeing, and finishing baths to improve wetting, leveling, and penetration of chemicals into fibers.
• Metalworking Fluids: Acts as an emulsifier and coupling agent in soluble oils and semi-synthetic coolants to stabilize the oil-water interface.
• Pulp & Paper Industry: Functions as a de-inking agent and dispersant in the recycling process and as a felt wash additive in paper production.
• Emulsion Polymerization: Serves as a non-ionic surfactant in the production of acrylic, vinyl acetate, and styrene-butadiene latexes.
