Sodium Gluconate (CAS No. 527-07-1, Molecular Formula: C6H11NaO7) has evolved from a niche biochemical compound into a fundamental chemical agent deployed widely across the global heavy-industrial, manufacturing, and agricultural landscapes. It acts as an exceptionally efficient chelating agent, concrete retarder, and scale inhibitor. Today, the global consumption of sodium gluconate exceeds millions of metric tons, fueled by a sweeping regulatory pivot towards biodegradable, non-toxic alternatives to traditional phosphorus-based and synthetic chelating agents like EDTA or NTA.
While Western markets present a steady demand, Asia-Pacific remains both the largest production hub and the fastest-growing market. Access to cost-effective raw corn starch provides a structural cost cushion for manufacturing facilities located in China.
Rapid growth in the formulation of polycarboxylate ether (PCE) superplasticizers requires a steady input of high-purity Sodium Gluconate to retard initial concrete setting times under challenging climatic conditions.
Sodium Gluconate stands out for its high biodegradability (completely degraded within days), low toxicity, and multi-functional performance profile, passing stringent food and feed grade approvals internationally.
Shandong Pulisi Chemical Co., Ltd. (Stock Code: 307785) stands at the forefront of China's fine chemical sector. Established in 2006, our long-term market presence and listing on public markets highlight our systemic commitment to transparency, quality verification, and capital strength. Our manufacturing footprint leverages China's industrial infrastructure, yielding exceptional cost and processing efficiencies.
Sodium Gluconate is produced through the deep fermentation of glucose derived from corn starch. Pulisi's strategic geographic placement within Shandong Province puts us in direct proximity to major agricultural zones. This integration minimizes raw material transit costs, provides insulation against price volatility, and secures a reliable supply chain.
Our facilities employ fully automated bio-fermentation tanks and closed crystallizing systems. This ensures a consistent purity profile above 99.0% and keeps impurity parameters such as reducing substances, heavy metals, and chloride levels well within regulatory limits.
Recognizing that delivery times are a key factor for international buyers, we have established mature warehousing and distribution hubs at key maritime ports, including Qingdao Port and Tianjin Port. Furthermore, our overland shipping routes run through strategic border ports such as Alashankou and Khorgos to serve the Eurasian and Central Asian markets, providing flexible, multimodal supply chain options.

The versatile molecular configuration of Sodium Gluconate allows it to perform functions such as chelation, set retardation, and corrosion inhibition. Here is how it functions in major global industries:
In concrete formulations, Sodium Gluconate delays the initial and final set times. When added in precise ratios (typically 0.05% to 0.15% by cement weight), it acts as a plasticizer and water reducer. It enables long-distance concrete transport, prevents cold joints, and improves the structural density of high-performance concrete structures.
Sodium Gluconate forms stable, water-soluble chelates with calcium, magnesium, iron, and aluminum ions under neutral and alkaline conditions. It is used as a scale and corrosion inhibitor in industrial cooling water loops, low-pressure boilers, and oilfield injection waters, protecting steel surfaces from oxidation.
In the textile sector, heavy metal ions in processing water can negatively impact dye affinity and brightness. Sodium Gluconate chelates these metal ions, preventing calcium and magnesium precipitation, which results in more uniform dyeing patterns and softer fabric finishes.
Within mining operations, Sodium Gluconate acts as a depressant and dispersion agent in froth flotation. Its chelation chemistry allows for selective mineral separation and prevents unwanted sludge deposits in processing pipes.
In high-temperature downhole environments, oil-well cementing requires precise retarders to prevent premature setting. Sodium Gluconate performs reliably under extreme thermal and pressure conditions, safeguarding deep drilling operations.
Formulations containing Sodium Gluconate are highly effective at cleaning rust, scale, and organic residues off steel sheets and glass bottles. Its clean rinsing characteristics make it an excellent choice for automated washing systems.
