Description

Potassium Glucoheptonate is the potassium salt of gluconic acid, a versatile and biodegradable chelating agent derived from renewable sources. This compound is valued for its excellent sequestering power for polyvalent metal ions, such as calcium, magnesium, and iron, across a wide pH range. It is a critical component for industries requiring effective scale inhibition, metal cleaning, and stabilization, including water treatment, construction, and industrial cleaning formulations.

Application

• Concrete Admixture: Acts as a highly effective set retarder and water reducer, improving the workability and final strength of concrete.
• Industrial Cleaning & Descaling: Used in alkaline and acidic cleaners to remove and inhibit hard water scale (calcium carbonate) and rust deposits from metal surfaces and equipment.
• Water Treatment: Functions as a scale and corrosion inhibitor in cooling water systems, boilers, and reverse osmosis membranes.
• Textile Processing: Serves as a chelant in scouring, bleaching, and dyeing baths to prevent metal-ion interference and improve process quality.
• Pulp & Paper Industry: Used in peroxide bleaching stages to stabilize hydrogen peroxide by sequestering transition metals that catalyze its decomposition.
• Agriculture: Employed in micronutrient fertilizers and foliar sprays as a carrier for metals like iron and zinc, enhancing plant uptake.
• Personal Care: Incorporated into formulations as a gentle chelating agent to improve stability and shelf life.

Quality Control

Our Potassium Glucoheptonate is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for purity, identity, and performance. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay, heavy metal content, and loss on drying. The product can be supplied to meet various industry standards, including food-grade (FCC) 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); the container must be kept tightly sealed after each use to prevent caking and degradation due to moisture absorption.
