Description

Disodium Iminodimethanesulphonate is a high-purity, water-soluble organic sulfonate salt with significant chelating properties. This compound is valued for its ability to form stable complexes with metal ions, making it a critical component in formulations requiring effective sequestration. It is primarily utilized by manufacturers in the detergent, water treatment, textile processing, and personal care industries where control of water hardness and metal ion interference is essential.

Application

• As a key chelating agent and builder in industrial and institutional detergent formulations to enhance cleaning efficiency.
• In water treatment processes for boiler and cooling systems to control scale formation and corrosion.
• As a stabilizing and sequestering agent in the textile industry for dyeing and bleaching processes.
• In the formulation of personal care products such as shampoos and soaps to improve stability and performance in hard water.
• As an intermediate in the synthesis of specialty chemicals and pharmaceuticals.
• In pulp and paper manufacturing to control metal ions during processing.
• For agricultural chemical formulations to improve the efficacy of certain active ingredients.
• In electroplating and metal finishing baths to complex impurities and improve bath life.

Quality Control

Our Disodium Iminodimethanesulphonate is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters are provided to guarantee traceability and batch-to-batch consistency, supporting your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
