Description

Maleic Acid Disodium Salt is the disodium salt of maleic acid, a versatile organic compound widely used as a chemical intermediate and chelating agent. Its primary value lies in its ability to sequester metal ions, making it crucial for controlling water hardness and preventing scale formation in industrial processes. This product is essential for manufacturers in the water treatment, detergent, textile, and paper industries who require reliable and effective chelating or buffering agents.

Application

• Water Treatment: Acts as a scale inhibitor and chelating agent in boiler and cooling water systems to control calcium and magnesium ions.
• Detergent & Cleaning Formulations: Used as a builder to enhance cleaning efficiency by softening water and preventing soap scum.
• Textile Processing: Serves as a chelant in dyeing and printing processes to improve color fastness and uniformity.
• Pulp & Paper Industry: Employed in bleaching processes to stabilize peroxides and improve pulp brightness.
• Chemical Synthesis: Functions as a key intermediate or catalyst in various organic synthesis reactions.
• Personal Care Products: Used as a pH adjuster and chelating agent in certain cosmetic and personal care formulations.
