Description

Disodium 3,3'-(2-Butyne-1,4-Diylbis(Oxy))Bis(2-Hydroxypropanesulphonate) is a high-purity, water-soluble sulfonate compound valued for its exceptional chelating and dispersing properties. This chemical is critical for industrial processes requiring precise control over metal ions and the prevention of scale formation. It is primarily utilized by manufacturers in the detergent, textile, water treatment, and personal care industries where performance and formulation stability are paramount.

Application

• Detergent & Cleaning Formulations: Acts as a powerful builder and sequestrant to enhance cleaning efficiency by inactivating water hardness ions (calcium, magnesium).
• Textile Processing: Used as a dispersing and leveling agent in dyeing processes to ensure uniform color uptake and prevent spotting.
• Industrial Water Treatment: Serves as a key component in scale and corrosion inhibitor formulations for cooling water and boiler systems.
• Personal Care Products: Functions as a chelating agent in shampoos, soaps, and lotions to improve stability and shelf life.
• Pulp & Paper Manufacturing: Employed as a dispersant for pigments and to control metal ions during bleaching and processing stages.
• Agricultural Chemicals: Enhances the efficacy and stability of certain pesticide and fertilizer formulations.

Storage

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