Description

Disodium 4-Octyl 2-Sulphonatosuccinate is a high-purity anionic surfactant belonging to the sulfosuccinate ester class. This compound is valued for its excellent wetting, emulsifying, and dispersing properties, particularly in systems requiring mildness and stability. It is a critical ingredient for formulators in the personal care, industrial cleaning, and agrochemical sectors seeking effective surface-active performance. Its compatibility with a wide range of other ingredients makes it a versatile component in complex formulations.

Application

• Personal Care & Cosmetics: As a primary or secondary surfactant in mild shampoos, body washes, facial cleansers, and baby care products due to its low irritation profile.
• Industrial & Institutional (I&I) Cleaning: In formulations for hard surface cleaners, metal degreasers, and vehicle wash systems where strong wetting and emulsification are required.
• Agrochemicals: As a wetting and dispersing agent in pesticide and herbicide formulations to improve spray coverage and active ingredient stability.
• Textile Processing: Used in dyeing and finishing baths to enhance dye leveling, penetration, and fabric wetting.
• Paints & Coatings: Acts as a pigment dispersant and wetting agent in water-based latex paints and industrial coatings.
• Emulsion Polymerization: Serves as an emulsifier in the production of synthetic rubbers, latexes, and acrylic polymers.

Quality Control

Our Disodium 4-Octyl 2-Sulphonatosuccinate is manufactured under a cGMP-compliant quality management system. Each batch undergoes rigorous analytical testing to ensure it meets stringent specifications for identity, purity, and performance. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing key parameters such as assay, moisture content, and residue on ignition. We support compliance with global regulatory frameworks including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Keep away from strong oxidizing agents and heat sources. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption.
