Diverse Application Fields

1. Detergent Industry

IDS effectively replaces traditional phosphorous-containing chelators and non-degradable EDTA in laundry detergents, powders, and cleaning products. It improves water softening capabilities and cleaning efficiency while meeting stringent global environmental regulations. Notably, IDS maintains excellent chelation performance even in low-temperature washing conditions, making it ideal for modern energy-saving washing processes.

2. Water Treatment

As an environmentally friendly scale inhibitor, IDS excels in industrial cooling water, boiler water, and RO systems. It prevents scale deposition of calcium and magnesium salts, protects equipment, and avoids environmental burdens associated with traditional chemicals. Numerous European chemical plants and power stations have adopted IDS as their primary water treatment agent, achieving significant economic and environmental benefits.

3. Textile Industry

In textile dyeing processes, IDS serves as both a hydrogen peroxide stabilizer and metal ion chelator. It prevents metal-ion-induced damage to dyes and fabrics, improves dyeing quality and uniformity, and reduces wastewater treatment challenges. Particularly in high-end textile processing, IDS has become the preferred environmental aid for many renowned brands.

4. Personal Care Products

Due to its mild nature, IDS is suitable for use in shampoos, body washes, and other personal care products as a chelating agent. It effectively stabilizes product formulations, extends shelf life, and meets consumer demands for product safety.

5. Agricultural Applications

As a chelating agent in micronutrient fertilizers, IDS enhances plant nutrient absorption and promotes crop growth while minimizing soil contamination.
