1. Food & Healthcare Ingredients

• Preservative: It acts as a preservative by preventing the growth of microorganisms in food, which helps extend shelf life. Sodium citrate is especially useful in dairy products, sauces, and beverages.
• Flavor Enhancer: It enhances the overall flavor profile of certain foods, particularly in beverages, by balancing the acidic notes and improving taste.
• Stabilizer & Thickener: Sodium citrate helps stabilize emulsions in dairy products, processed cheese, and certain beverages, preventing ingredients from separating. It functions as a thickening agent in sauces, soups, and desserts, improving texture and consistency.

2. Pharmaceuticals

• Buffering Agent: Sodium citrate is widely used in pharmaceutical formulations as a buffering agent, maintaining the pH balance of liquid medications, oral solutions, and intravenous fluids.
• Antacid: It is used as an active ingredient in antacid medications to neutralize stomach acid and relieve symptoms of indigestion, heartburn, and acid reflux.
• Blood Thinner: In medical applications, sodium citrate is used in blood collection and storage to prevent blood clotting by acting as an anticoagulant.

3. Personal Care 

• pH Adjuster: Sodium citrate is used in cosmetics and personal care products to adjust the pH, ensuring that formulations are gentle on the skin and stable over time.
• Stabilizer: It is used to stabilize certain ingredients in skincare products, such as vitamin C, which is sensitive to oxidation, thus prolonging the shelf life and effectiveness of the product.
• Exfoliant: In some formulations, sodium citrate is included for its mild exfoliating properties, helping to gently remove dead skin cells and promote skin renewal.

4. Chemical Synthesis 

• Buffering Agent: Sodium citrate is used in various chemical processes to maintain a stable pH, which is crucial for optimal chemical reactions, particularly in industrial applications like water treatment.
• Chelating Agent: It acts as a chelating agent in some chemical processes by binding to metal ions, preventing them from interfering with chemical reactions or degrading other compounds.
• Food-Grade Chemical: In chemical manufacturing, sodium citrate is often used as a food-grade chemical for producing citric acid, which has applications in both food and non-food industries.

5. Fabric Solutions

• Dyeing Agent: Sodium citrate is used in the textile industry to assist in the dyeing process, especially with synthetic fibers. It helps improve the uptake of dye and ensures consistent color across fabrics.
• Finishing Agent: It is sometimes used in fabric finishing processes to enhance the feel and appearance of textiles, making them softer or more resistant to wrinkles.
• Water Softening: In some textile manufacturing processes, sodium citrate is used as a water softener, reducing the hardness of water and preventing the interference of minerals with dyeing and washing.
