Product Description

What’s the Tetrasodium iminodisuccinate(IDS-na4)

Tetrasodium iminodisuccinate (IDS-Na4) is a green and water-soluble complexing agent which is a new-generation biodegradable water treatment chemical with excellent chelating and complexing properties.Tetrasodium Iminodisuccinate (TIDS) is a highly effective chelating agent widely used in industrial and commercial applications. It is a versatile green alternative to traditional phosphates and phosphonates, offering superior performance in preventing scale formation, improving the effectiveness of detergents, and enhancing overall product efficiency.


Tetrasodium Iminodisuccinate works by binding to metal ions in water and other systems, preventing the negative impact of minerals on product performance. As a biodegradable and non-toxic solution, it is increasingly favored in industries that prioritize sustainability and environmental responsibility.

IDS can form a quintuple-bonded complex with metal ions. In this case, complexing occurs via nitrogen and all four carboxyl groups. As a result of the octahedral structural of the complete complex, a water molecule is required for the sixth coordination point, which makes it significantly effects than other complex agents.

100℃ environment: under the condition of PH<1.5, after 20h, the stability is not less than 40%; under the condition of PH>4 (including ph=14), after 20h, the stability is not less than 80%; 50℃ and In the following environments, the stability of IDS does not change much with pH, and after 24 weeks, the stability is not less than 90%.

Product Properties

  • Physical stability: the solution is easy to crystallize at 5°C and below
  • Chemical stability: IDS can maintain good stability in strong acid and strong alkali mediums. The stability in an alkaline environment is better than in an acid environment, and the stability is good in neutral conditions.
  • Easily biodegradable, and eco-friendly.
  • Excellent compatibility, strong alkali resistance, high pH value, and high-temperature resistance.
  • Good stability to hydrogen peroxide H2O2. Used in hydrogen peroxide oxygen bleach stabilizer.

Main Applications

The Applications of Tetrasodium iminodisuccinate(IDS-Na4)

  • As a complexing agent, IDS is used as a cleaning agent for alkaline earth metals and heavy metal ions. It is widely used in civil cleaning agents, industrial cleaning agents, photography industry cleaning agents, printing and dyeing auxiliaries, dyeing and finishing processes, the textile industry, the paper industry, photosensitive materials, and the ceramics industry, the electroplating industry, the construction industry, and extraction of heavy metal pollutants from soil.
  • In the field of traditional industrial circulating water, IDS is also used as a scale inhibitor and water softener. For cleaning hard surfaces, it can be used with surfactants to achieve excellent results. Neutral cleaning agent for removing rust and iron sulfide scale in metal pipeline networks, especially recommended for natural gas pipeline cleaning.
  • IDS can chelate various trace elements in agriculture and supplement plant trace elements. Ionic trace elements are easy to react with phosphate and other substances in the soil to deposit and solidify. In contrast, chelated trace elements can be quickly and directly absorbed by plants, with a high utilization rate and immediate effect. IDS chelated trace elements can be used alone, or added to water-soluble fertilizer, foliar fertilizer, NKP, etc.
  • In the food industry, the addition of IDS in the wine and red wine manufacturing process can prevent floc floating and prevent sedimentation.
  • Surface cleaning: IDS is a component with excellent performance in metal cutting, pipeline network cleaning, and glass cleaning. It has a better effect when used with surfactant, which can significantly enhance the decontamination ability of the product, especially for rust and iron sulfide substances. It can be widely used in various industrial cleaning agents and is especially recommended for natural gas pipeline cleaning.
  • Detergents and daily cleaning agents: When IDS is used in detergents and daily cleaning products, IDS can enhance the decontamination ability of the product, and its excellent complexing ability increases the solubility of calcium and magnesium ions so that the surfactant can function normally. In addition, its environmental protection also increases the safety of daily washing products, and when used in soaping agents, it can increase the vividness of colors.
  • Cosmetics: IDS forms stable water-soluble complex molecules with heavy metal ions, thereby reducing the catalytic effect of heavy metal ions on the oxidation of unsaturated fatty acids in cosmetics. Its biodegradability provides safer product quality and reduces the risk of adverse skin reactions.
  • Bleaching in papermaking and printing and dyeing industries: IDS can be used for hydrogen peroxide bleaching in various processes, especially in high-temperature alkaline environments. It has excellent performance. It can complex catalysts such as copper necessities and iron ions that catalyze the decomposition of bleaching agents. In addition, the whiteness of the obtained products is also much better than using conventional oxidizing agents. When mixed with sodium silicate, it can reduce the formation of silica scale.
  • Anti-corrosion preservation of light chemical products: During the storage process of light chemical products, oxidation, aging, solidification, discoloration, strength reduction, and other deterioration problems are common. These problems are related to the catalytic effect of metal ions. IDS has a strong ability to chelate high-valent metal ions, which can effectively reduce The catalytic activity of metal ions prolonging the shelf life of the product. Moreover, it can be used in conjunction with fungicides to improve the inhibitory effect on certain microorganisms and prevent product spoilage.
