Sodium gluconate is a compound with formula NaC6H11O7. It is the sodium salt of gluconic acid (E576). This white, water-soluble powder is derived from gluconic acid and is widely recognized for its excellent chelating properties.
It is non-toxic, biodegradable, and used extensively as a chelating agent in industries ranging from construction to food processing.
Water Treatment: Effectively chelates calcium, magnesium, and iron ions in hard water, preventing scale and corrosion in cooling towers and boilers.
Metal Treatment: Used in electroplating and metal cleaning to stabilize bath chemistry and improve surface finishes.
Concrete & Construction: Acts as a set retarder, extending workability time and improving pumpability without sacrificing final strength.
Serves as a sequestrant, stabilizer, and acidity regulator (E576) in foods and beverages. Also used as an excipient in pharmaceuticals for buffering.
Assists in micronutrient delivery (iron, zinc) by chelating metals in fertilizers, significantly improving plant uptake.
High chelation efficiency across wide pH ranges, environmentally friendly biodegradability, and GRAS safety status.
