Description

Pentapotassium Pentasodium Bis(Triphosphate) is a high-purity, mixed alkali metal polyphosphate salt with versatile sequestering and dispersing properties. This compound is valued for its superior ability to bind metal ions, control water hardness, and prevent scale formation in industrial processes. It serves as a critical performance additive for manufacturers in the detergent, water treatment, food processing, and industrial cleaning sectors seeking effective and reliable multi-functional agents.

Application

• Detergent & Cleaning Formulations: Acts as a powerful builder to sequester calcium and magnesium ions, enhancing surfactant efficiency and preventing soap scum in laundry detergents, dishwashing liquids, and industrial cleaners.
• Water Treatment: Used as a scale and corrosion inhibitor in cooling towers, boiler water systems, and reverse osmosis membranes to control precipitation of hardness salts.
• Food Industry: Employed as a sequestrant, texturizer, and moisture-retaining agent in processed meats, poultry, seafood, and dairy products to improve quality and shelf-life.
• Industrial Process Aid: Serves as a dispersant and peptizing agent in ceramic production, pigment dispersion, and drilling mud formulations.
• Metal Surface Treatment: Used in metal cleaning and finishing processes to chelate metal ions and prevent undesirable precipitation.
• Oil Field Chemicals: Functions as a scale inhibitor in oil recovery and production systems to maintain well and pipeline efficiency.

Quality Control

Our Pentapotassium Pentasodium Bis(Triphosphate) is manufactured under a stringent quality management system. Each batch is tested to ensure it meets precise specifications for assay, phosphate content, and impurity levels. Certificates of Analysis (COA) documenting purity, heavy metal content, and other critical parameters are provided to guarantee consistency and compliance with relevant industry standards, including food-grade (FCC) specifications where applicable.

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). Keep the container tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking and reduced efficacy.
