Description

Sodium 1,4-Bis(1-Isobutyl-3-Methylbutyl) Sulphonatosuccinate is a high-purity, specialty anionic surfactant belonging to the class of sulfosuccinate esters. This compound is valued for its excellent wetting, emulsifying, and dispersing properties, particularly in demanding formulations. It is a critical ingredient for industries requiring high-performance surface-active agents, such as agrochemicals, coatings, and industrial cleaning. Our product is supplied to meet the stringent quality and consistency demands of global B2B customers.

Application

• Primary emulsifier and wetting agent in agricultural formulations (e.g., herbicides, insecticides, fungicides).
• Key dispersant and stabilizer in polymer emulsions and coating systems.
• High-performance surfactant in industrial and institutional (I&I) cleaning products.
• Emulsifier for metalworking fluids and lubricant additives.
• Wetting and leveling agent in textile processing and dyeing applications.
• Dispersant for pigments and fillers in paper coating and construction chemicals.
• Component in specialty personal care formulations requiring mild surfactants.
• Additive for enhanced oil recovery (EOR) and petroleum industry applications.

Quality Control

Our Sodium 1,4-Bis(1-Isobutyl-3-Methylbutyl) Sulphonatosuccinate is manufactured under a cGMP-compliant quality management system (ISO 9001 certified). Every batch undergoes rigorous analytical testing to ensure identity, purity, and performance consistency. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing key parameters such as assay, moisture content, and residue levels. We support compliance with global regulatory frameworks including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
