IDS 4Na/Tetrasodium Iminodisuccinate

Sodium salt of iminodisuccinic acid, a highly efficient green chelating agent.
Excellent metal ion chelating ability, widely used in multiple fields. Good
biodegradability, environmentally friendly and non-toxic. Assist in improving
product performance and provide reliable, innovative, and sustainable solutions
for your industrial and environmental needs
Tetrasodium iminodisuccinate (IDS) is an efficient green amino acid chelating
agent. Due to its better chelating ability than EDTA, it is easily absorbed by
plants, has good biocompatibility, and is easily degraded. It is recognized by
the industry as an ideal substitute for EDTA in the 21st century and is called
a fertilizer enhancing chelating agent. 

What Is Iminodisuccinate Sodium Salt?
Iminodisuccinate sodium salt is a water-soluble, biodegradable chelating agent
derived from renewable resources. With its outstanding ability to bind with
metal ions such as calcium, magnesium, iron, and copper, IDS (also
called IDHA, sodium of iminodisuccinate, or sodium iminodisuccinate) plays a
critical role in enhancing cleaning, bleaching, and fertilizing processes.

Key Benefits of IDS / IDHA

Excellent biodegradability and eco-friendliness

Non-toxic, making it safe for household and industrial use

Strong chelating power with high complex stability

Easily absorbed by plants, increasing nutrient efficiency

Ideal alternative to EDTA in many applications

Applications of Sodium Iminodisuccinate
1. Complexing agent and water softener:
Sodium salt of iminodisuccinic acid enhances the efficiency
of detergents and cleaning products by preventing scale buildup and
improving overall cleaning performance. Its exceptional safety and
biodegradability make it ideal for modern, eco-friendly formulations.
2. Bleaching agent stabilizer:
Iminodisuccinic acid sodium salt could be used as stabilizer in oxidative
bleaching of cotton with H2O2 in a variety of processes. It complexes iron and
copper ions which would otherwise cause catalytic decomposition of the
bleaching agent.Meanwhile it is water softener for water pretreatment.
3. Fertilizer micronutrients: 
IDS is widely used in agriculture to create biodegradable micronutrient
chelate fertilizers for foliar sprays, soil applications, hydroponics, and
fertigation. Its superior chelation increases the availability and absorption
of trace elements by plants.
