Description

Sodium Gluconate is the sodium salt of gluconic acid, a versatile and highly effective chelating agent and sequestrant. Its primary value lies in its exceptional ability to bind and deactivate metal ions, particularly calcium and iron, in alkaline solutions, preventing scale formation and stabilizing product formulations. This makes it a critical component for industries requiring superior cleaning, corrosion inhibition, and process stabilization, such as construction, industrial cleaning, water treatment, and food processing.

Application

• Construction & Concrete Admixture: Acts as a highly effective set retarder and water reducer in concrete, improving workability and final strength.
• Industrial & Institutional (I&I) Cleaning: A key chelant in alkaline bottle washing formulations, metal cleaners, and dairy detergents to prevent scale and enhance cleaning efficacy.
• Water Treatment: Used for scale and corrosion inhibition in cooling towers, boilers, and reverse osmosis systems.
• Food Industry (Food Grade): Functions as a sequestrant, stabilizer, and acidity regulator in beverages, dairy products, and canned goods.
• Agriculture: Serves as a micronutrient carrier in fertilizers and a chelating agent in agrochemical formulations.
• Textile & Leather Processing: Used in dyeing and tanning baths to complex metal ions that can interfere with processes and affect color quality.
• Plating & Metal Surface Treatment: Employed in electroplating and metal finishing baths for improved surface quality and deposit uniformity.
• Pharmaceuticals & Cosmetics: Used as a stabilizing agent and chelant in certain topical formulations and personal care products.
