Description

Dipotassium 1,5-Dihydroxypentane-1,5-Disulphonate is a high-purity, water-soluble organic salt primarily valued for its excellent chelating and sequestering properties. This compound is crucial for industrial processes requiring the control of metal ions to prevent scaling, stabilize formulations, and enhance performance. It is essential for manufacturers in sectors such as detergents, water treatment, textile processing, and personal care where reliable chemical performance is critical.

Application

• Detergent & Cleaning Formulations: Acts as a powerful builder and sequestrant to inactivate water hardness ions (calcium, magnesium), improving surfactant efficiency and preventing scale deposition.
• Industrial Water Treatment: Used in cooling water systems, boilers, and reverse osmosis membranes as a scale and corrosion inhibitor.
• Textile Processing: Serves as a chelating agent in dyeing and bleaching baths to ensure consistent color quality and prevent metal-catalyzed fiber damage.
• Personal Care Products: Incorporated into shampoos, liquid soaps, and other formulations to stabilize ingredients and improve clarity by binding trace metals.
• Pulp & Paper Industry: Enhances bleaching processes and improves pulp brightness by chelating transition metals.
• Agricultural Chemicals: Used in certain fertilizer and pesticide formulations to improve stability and bioavailability.
• Metal Surface Treatment: Assists in plating baths and metal cleaning solutions by controlling free metal ions.

Quality Control

Our production of Dipotassium 1,5-Dihydroxypentane-1,5-Disulphonate adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing to ensure consistent purity and performance. Certificates of Analysis (COA) documenting key parameters such as assay, identity, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after initial use to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
