In demanding environments of high temperature and strong alkali, an environmentally friendly chelating agent maintains over 80% stability at 100°C and pH 14, emerging as a preferred choice in industrial applications.

In the textile printing and dyeing industry, treating cotton requires hydrogen peroxide stabilizers to function in high-concentration alkali solutions (alkali concentration up to 40 g/L) and elevated temperatures. Similarly, industrial circulating water systems operate under high temperatures and varying pH conditions, where traditional chelating agents often struggle to maintain long-term performance stability.

Tetrasodium Iminodisuccinate (IDS), a novel green chelating agent, demonstrates exceptional stability under extreme conditions such as high temperature and strong alkalinity, gradually replacing traditional products like EDTA and DTPA.

01 Chemical Properties and Core Advantages

Tetrasodium Iminodisuccinate (IDS) is an ecological and environmentally friendly chelating agent with the molecular formula C8H7NO8Na4. Its uniqueness lies in being phosphorus-free and readily biodegradable. It exhibits strong chelating capability for alkaline earth metal ions like calcium and magnesium, as well as heavy metal ions including copper, iron, manganese, and nickel.

Regarding physical properties, IDS appears as a colorless to pale yellow transparent liquid at room temperature. It is important to note that prolonged exposure to temperatures below 5°C may cause crystallization. From an application perspective, the main advantages of IDS are its environmental friendliness and broad applicability. As a "green" chemical, it is biodegradable and non-toxic to ecosystems, making it particularly suitable for sectors requiring eco-friendly solutions.

02 Exceptional High-Temperature Stability Performance

The high-temperature resistance of IDS is one of its most prominent technical advantages. Research data indicates that this chelating agent maintains high stability even under extreme temperature conditions.

In a 100°C environment, the stability of IDS closely correlates with pH levels. Experimental data shows that under strong acidic conditions (pH below 1.5), its stability remains above 40% after 20 hours. In contrast, at pH levels equal to or greater than 4 (including highly alkaline environments up to pH 14), stability remains no less than 80% after the same duration.

The effect of temperature on IDS stability exhibits a clear threshold. At 50°C and below, the compound's stability shows little variation with pH changes, maintaining over 90% stability even after 24 weeks (approximately 6 months) of testing. This characteristic makes it especially suitable for applications requiring long-term performance in heated environments, such as industrial water treatment and high-temperature cleaning agents.

03 Outstanding Alkali Resistance and Stability

IDS demonstrates exceptional stability in alkaline environments, a key factor enabling it to replace traditional chelating agents in many industrial applications. Chemical stability studies show that IDS maintains good stability in both strong acid and strong alkali media, with performance notably more robust in alkaline conditions.

Application validation confirms that IDS maintains stable performance even at alkali concentrations as high as 40 g/L, covering the practical requirements of most industrial alkaline environments. This excellent alkali resistance makes it an ideal hydrogen peroxide stabilizer in the textile printing and dyeing industry. In the oxygen bleaching process for cotton, the treatment liquor is typically highly alkaline and at elevated temperatures, where traditional hydrogen peroxide stabilizers often fail to maintain long-term activity. IDS not only remains stable under such harsh conditions but also effectively inhibits hydrogen peroxide decomposition, improving bleaching efficiency and consistency.

04 Comprehensive Application Stability and Environmental Features

Beyond high-temperature and alkali resistance, IDS exhibits good overall stability in various application environments. Its stability is particularly outstanding under neutral conditions. This comprehensive stability allows IDS to adapt to diverse and complex industrial settings, maintaining consistent chelating performance from strong acid to strong alkali, and from ambient to high temperatures.

Regarding hydrogen peroxide stabilization, IDS shows excellent stabilizing effects, making it a highly efficient oxygen bleaching stabilizer. From an environmental performance perspective, the ready biodegradability of IDS is a significant advantage. Compared to traditional chelating agents, it does not persist in the environment after use but is broken down by microorganisms, thereby reducing long-term ecological impact. This characteristic aligns well with the global pursuit of green chemistry and sustainable development.

06 Multi-Sector Applications and Market Demand

Due to its exceptional stability performance, IDS has found wide application across numerous industrial fields. In the textile printing and dyeing industry, it serves as an efficient hydrogen peroxide stabilizer and dyeing auxiliary, maintaining stable performance during high-temperature, high-alkali bleaching and dyeing processes. In the paper industry, IDS is used as an alkaline complexing agent to help control the impact of metal ions on the papermaking process. In ceramics and electroplating industries, it acts as an effective metal ion chelator, improving product quality and production efficiency.

In environmental protection, IDS can be used for extracting heavy metal contaminants from soil, aiding in the remediation of polluted land. In agriculture, it can serve as a chelating agent for soil micronutrient fertilizers, enhancing fertilizer utilization efficiency. In water treatment, particularly in industrial circulating water systems, IDS functions as a scale inhibitor and water softener, effectively controlling scale formation under varying temperatures and pH conditions. In the cleaning agent industry, whether for industrial or household detergents, it maintains stable chelating performance in alkaline environments.

At room temperature, IDS is a colorless to pale yellow transparent liquid. Its aqueous solution demonstrates good physical stability, although prolonged exposure to temperatures below 5°C may lead to crystallization. Chemically, it maintains stable chelating performance even in strong alkaline media, with performance being particularly robust in alkaline environments. Even when challenged by the dual extremes of 100°C heat and strong alkali, it retains over 80% activity.
