Description

Sodium Nonylbenzenesulfonate is a high-performance anionic surfactant derived from nonylbenzene. This compound is valued for its excellent wetting, emulsifying, and dispersing properties in aqueous systems. It is a critical raw material for formulators in the industrial cleaning, agrochemical, and textile processing sectors who require reliable and effective surface-active agents.

Application

• Industrial & Institutional (I&I) Cleaners: A key component in heavy-duty degreasers, alkaline cleaners, and floor care formulations for its powerful emulsification of oils and fats.
• Agrochemical Formulations: Used as a wetting agent, dispersant, and emulsifier in pesticide and herbicide concentrates to improve spray coverage and efficacy.
• Textile Processing: Employed in scouring, dyeing, and finishing baths to enhance penetration and ensure uniform processing of fibers and fabrics.
• Emulsion Polymerization: Serves as an effective emulsifier and stabilizer in the production of synthetic latexes, such as styrene-butadiene rubber (SBR) and acrylics.
• Oilfield Chemicals: Functions as a surfactant in drilling muds and enhanced oil recovery (EOR) formulations to modify interfacial tension.
• Paint & Coating Additives: Acts as a pigment dispersant and grinding aid to improve color development and stability in water-based systems.
• Leather Processing: Used in soaking, degreasing, and dyeing stages to improve chemical penetration and processing uniformity.

Quality Control

Our Sodium Nonylbenzenesulfonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance and meets specifications for critical parameters such as active matter content, free oil, and inorganic salt levels. Certificates of Analysis (COA) documenting these results are available for every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent caking and maintain product integrity.
