Sodium Gluconate

Sodium Gluconate is the sodium salt of gluconic acid. It is a highly effective chelating agent, especially in alkaline conditions, and is widely used in various industries such as food, pharmaceuticals, and construction.

Chemical Properties:

• Chemical Formula: C₆H₁₁NaO₇
• Molecular Weight: 218.14 g/mol
• Density: Approximately 1.54 g/cm³
• Solubility: Highly soluble in water, slightly soluble in alcohols.
• pH: Neutral to mildly alkaline (pH of a 10% solution is about 6.5 to 8.5)

Physical Characteristics:

• Appearance: White to off-white crystalline powder or granules.
• Odor: Odorless.
• Taste: Slightly salty.

Common Uses:

1. Construction Industry:
   • Concrete Additive: Used as a retarder in concrete mixtures, delaying the setting time to allow for proper handling and working of the cement. It also improves the durability and strength of concrete.
   • Plasticizer: Enhances the workability of concrete without increasing water content.
2. Food and Beverages:
   • Food Additive (E576): Acts as a sequestrant, stabilizer, and thickener. It is used to prevent oxidation and improve the texture of certain food products.
   • Preservative: Helps extend the shelf life of food products by inhibiting spoilage due to oxidation or microbial growth.
3. Detergents and Cleaners:
   • Chelating Agent: Effectively binds with metal ions (such as calcium and magnesium), which helps to soften water and enhance the cleaning ability of detergents, soaps, and industrial cleaning products.
4. Pharmaceuticals:
   • Medical Applications: Used in the formulation of medications and supplements due to its ability to improve mineral absorption in the body.
   • Chelation Therapy: Employed in certain medical treatments where it binds to heavy metals in the body for removal.
5. Water Treatment:
   • Corrosion Inhibitor: Prevents the formation of scale and corrosion in industrial water systems by sequestering metal ions such as iron and manganese.
6. Cosmetics and Personal Care:
   • pH Stabilizer: Used in personal care products like lotions and shampoos to stabilize pH levels.
   • Moisturizer: Helps to improve skin hydration and maintain moisture balance.
7. Textile and Paper Industries:
   • Dyeing and Bleaching: Acts as a stabilizer during the dyeing and bleaching process to prevent discoloration and enhance color retention.

Safety and Handling Considerations:

1. Safety:
   • Low Toxicity: Sodium gluconate is considered safe and non-toxic when handled properly. It poses minimal risk to health and the environment.
   • Non-corrosive: Unlike many industrial chemicals, sodium gluconate is non-corrosive, making it safer to handle.
2. Handling:
   • Storage: Store in a cool, dry place, away from moisture and heat. Keep containers tightly sealed to prevent clumping or contamination.
   • Ventilation: Ensure adequate ventilation when handling large quantities to avoid inhaling dust.
3. Emergency Procedures:
   • Spills: Sweep up and dispose of in accordance with local environmental regulations. Avoid generating dust during cleanup.
   • Exposure: In case of skin or eye contact, wash thoroughly with water. If ingested in large amounts, seek medical attention.
4. Disposal:
   • Regulations: Generally regarded as safe for disposal in regular waste streams, but disposal should follow local environmental regulations.
