Description

Sodium Dihydrogen 2-Sulphonatosuccinate is a versatile and high-performance anionic surfactant and complexing agent. This compound is valued for its excellent chelating power, biodegradability, and effectiveness in hard water, making it a superior alternative to traditional phosphates. It is essential for formulators and manufacturers in industries such as detergents, personal care, and industrial cleaning who require effective sequestration, soil suspension, and anti-redeposition properties.

Application

• Detergent & Cleaning Formulations: Key component in liquid and powder detergents for its superior calcium ion sequestration, anti-redeposition, and soil suspension capabilities.
• Personal Care Products: Used in shampoos, body washes, and liquid soaps as a mild surfactant and chelating agent to enhance foam stability and performance in hard water.
• Industrial & Institutional (I&I) Cleaners: Employed in hard surface cleaners, dishwashing liquids, and metal cleaning formulations for its effective scale inhibition and cleaning power.
• Textile Processing: Functions as a chelating agent and dispersant in scouring, bleaching, and dyeing baths to improve process efficiency and fabric quality.
• Pulp & Paper Industry: Acts as a chelant and dispersant in bleaching processes to enhance brightness and protect equipment from scale.
• Agricultural Formulations: Used as a solubilizer and compatibility agent in pesticide and herbicide concentrates.
• Water Treatment: Serves as a scale inhibitor and dispersant in cooling water and boiler water systems.
• Photographic Industry: Utilized in developing solutions as a sequestering agent for metal ions.

Quality Control

Our Sodium Dihydrogen 2-Sulphonatosuccinate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, activity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical parameters is provided with each shipment to guarantee consistency and 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 to prevent absorption of atmospheric moisture which can lead to caking or reduced efficacy.
