Sodium gluconate

Sodium gluconate (CAS 527-07-1), also known by its food additive designation E576, is the sodium salt of gluconic acid produced through fermentation of glucose.

Where is Sodium gluconate used?

• Industrial and food-grade: chelating agent that sequesters metal ions
• Formulation systems: pH buffer where stability and controlled acidity are critical
• Concrete and cement: set retarder and water reducer improving workability and compressive strength in ready-mix and precast operations
• Water treatment: controls scale and metal ion deposition in boilers, cooling towers and industrial pipework
• Food and beverage: E576 as mineral supplement carrier and acidity regulator in dairy products and beverages
• Textile and leather processing: sequesters calcium and magnesium ions in hard water, preventing interference during dyeing and finishing
• It is also used in processed foods.
• Personal care: used in dental care, skin care and toiletries.
• Meat products: food-grade material acts as a stabilizer by increasing water-binding capacity and improving firmness and sliceability.
• Meat products: can replace phosphates.

Formulation notes

• Reacts with strong oxidants.
• A superior chelating agent to EDTA, NTA and phosphonates.

Typical specification

• Readily biodegradable, 98% after 2 days.
• Food grade, technical grade, feed grade, USP grade and Personal Care grade are available on the market.
• Solubility in water is 59 g/100 ml at 25°C.

Regulatory status

• An anti-dumping investigation concerning material originating in the People's Republic of China has been initiated by Türkiye, published as Communiqué No. 2025/9.
• Exempted from EU REACH registration by Commission Regulation (EC) No. 987/2008, so no registration is required.
