Description

Nonylbenzenesulphonic Acid is a key organic sulfonic acid derivative widely used as a versatile chemical intermediate. Its strong acidic nature and surfactant properties make it a critical component in the synthesis of high-performance anionic surfactants and industrial cleaners. This product is essential for manufacturers in the detergent, agrochemical, and textile processing industries seeking reliable raw materials for formulation.

Application

• Primary Surfactant Intermediate: The predominant use is in the production of linear alkylbenzene sulfonate (LAS) surfactants for household and industrial detergents.
• Industrial & Institutional (I&I) Cleaners: Acts as a powerful wetting and emulsifying agent in heavy-duty degreasers, metal cleaners, and floor care formulations.
• Textile Processing: Employed as a scouring and wetting agent in the pretreatment and dyeing of textiles and fibers.
• Agrochemical Formulations: Used as an emulsifier and dispersant in the production of pesticides, herbicides, and other crop protection products.
• Emulsion Polymerization: Serves as an anionic emulsifier in the synthesis of polymers, such as styrene-butadiene and acrylic lattices.
• Acid Catalyst: Functions as a strong organic acid catalyst in various organic synthesis reactions.

Quality Control

Our Nonylbenzenesulphonic Acid is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. The product undergoes rigorous testing, including assay, active matter content, and free sulfuric acid determination. A Certificate of Analysis (COA) documenting all key specifications is provided with every shipment to guarantee compliance with your formulation requirements.

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) and a strong acid/organic solvent; containers must be kept tightly sealed to prevent moisture absorption and degradation. Keep away from incompatible materials such as strong bases and oxidizing agents.
