When sourcing chemical raw materials for your business, understanding the specifics of each compound is paramount. EDTA Disodium Salt, with the CAS number 139-33-3, is a highly versatile chelating agent that plays a critical role across various industries. As a dedicated supplier of this essential chemical, we aim to provide you with comprehensive information to facilitate your purchase decisions.

EDTA Disodium Salt, also known as Disodium edetate dihydrate, is characterized by its white crystalline powder appearance. Its excellent solubility in water, contrasted with poor solubility in organic solvents like alcohol and ethyl ether, makes it convenient for aqueous formulations. The pH of a 5% water solution typically ranges between 4.0 and 6.0, indicating its slightly acidic nature.

The primary function of EDTA Disodium Salt is its ability to form stable, water-soluble complexes with metal ions. This property makes it an indispensable component in numerous applications. For instance, in the food industry, it is recognized for its role as a food additive, particularly in canned aquatic products and syruped chestnuts. Its inclusion helps maintain the desired color, fragrance, and taste of these products. Furthermore, it plays a vital role in preventing the precipitation of struvite crystals in processed seafood like crab and shrimp, thereby ensuring superior product quality and appeal. As a stabilizer and coagulant for pickles and canned foods, its maximum permitted usage is regulated to ensure safety.

Beyond food applications, EDTA Disodium Salt is a key ingredient in cosmetics, acting as a stabilizer and enhancing the efficacy of various personal care products. Its chelating properties are also highly valued in detergents and cleaning agents, where it helps to sequester metal ions, thereby improving the cleaning power and preventing the formation of soap scum. In the textile and dyeing industries, it serves as a crucial dyeing assistant and fiber processing agent, ensuring uniform coloration and enhanced fabric properties.
