Description

Iso-Ppads Tetrasodium Salt is a high-purity, water-soluble organic salt designed for advanced industrial applications. This compound is valued for its exceptional chelating and stabilizing properties, which are critical in formulations requiring precise control over metal ions and pH. It serves as a key functional additive in sectors such as specialty detergents, water treatment, textile processing, and personal care product manufacturing, where performance and consistency are paramount.

Application

• Detergent & Cleaning Formulations: Acts as a powerful builder and chelating agent to inactivate water hardness ions, enhancing surfactant efficiency and preventing scale.
• Industrial Water Treatment: Used as a scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems.
• Textile Processing: Serves as a chelant and stabilizer in dyeing and bleaching baths to improve color fastness and process uniformity.
• Personal Care Products: Incorporated into formulations like shampoos and liquid soaps as a stabilizer and sequestrant to improve shelf-life and clarity.
• Pulp & Paper Industry: Utilized in bleaching processes to stabilize peroxides and improve brightness yield.
• Metal Surface Treatment: Functions in cleaning and plating baths to complex interfering metal ions and ensure surface quality.
