Description

Tridecanedioic Acid Disodium Salt is a high-purity, water-soluble salt of a long-chain dicarboxylic acid, valued for its role as a versatile intermediate and functional additive. This compound is particularly significant for its ability to act as a chelating agent, surfactant, or corrosion inhibitor in demanding formulations. It is essential for manufacturers in the personal care, industrial cleaning, and specialty chemical synthesis sectors seeking reliable performance and consistent quality.

Application

• Surfactant and Detergent Intermediate: Used in the synthesis of high-performance surfactants for industrial and institutional cleaning products.
• Corrosion Inhibitor: Functions as an effective additive in cooling water systems and metalworking fluids to protect ferrous and non-ferrous metals.
• Chelating Agent: Binds with metal ions in aqueous systems, preventing scale formation and improving the stability of formulations in cleaning and textile processing.
• Personal Care Ingredient: Employed as a buffering agent or mild chelant in cosmetic and personal care formulations such as shampoos and skin cleansers.
• Polymer Synthesis: Serves as a monomer or chain extender in the production of polyesters, polyamides, and other specialty polymers.
• Laboratory Reagent: Used as a standard or analytical reagent in chemical research and quality control laboratories.
