Sodium Carbonate for Pharmaceutical Applications

Anhydrous Sodium Carbonate (CAS No. 497-19-8) plays an important role in the pharmaceutical industry due to its alkaline properties, pH-regulating ability, and effervescence properties. Below are some key applications of Sodium Carbonate in pharmaceutical formulations:

pH Regulation in Pharmaceutical Formulations

Sodium Carbonate is used to regulate the pH of various pharmaceutical formulations. It helps maintain a stable pH in medicines, ensuring their efficacy and stability. This is particularly important for oral solutions, syrups, and topical formulations.

Effervescent Tablets and Oral Dosage Forms

• Effervescent Tablets: It is a key ingredient in effervescent tablets and powders, where it reacts with acids (such as citric acid) to produce carbon dioxide (CO₂) gas. This gas helps tablets dissolve quickly in water, making them easier to swallow and increasing the absorption rate of the active ingredients.
• Fast-Release Formulations: It improves the bioavailability of active pharmaceutical ingredients by aiding their rapid release in liquid form.

Excipients in Tablet Formulation

Binder and Disintegrant: It helps in the disintegration of tablets in the digestive tract, ensuring the drug's effectiveness is achieved once ingested.

Sodium Carbonate for Food Applications

Sodium Carbonate is widely used in the food industry due to its alkaline properties, ability to regulate acidity, and functionality as a leavening agent. It is approved under E number E 500(i) as food additive. Here are some of the main applications of Sodium Carbonate in food production:

pH Regulation in Food Products

• Acidity Regulation: Sodium Carbonate is used to control the acidity or pH levels in foods. It helps maintain desired pH levels in products such as beverages, confectionery, and dairy products, ensuring the stability, texture, and flavor of the products.
• Alkalizing Cocoa: It is commonly used in the alkalization of cocoa powder, a process that mildens the bitterness of cocoa and improves the color and texture of chocolate products.

Leavening Agent and Baking Powder

• Sodium Carbonate is a component in baking powders and leavening agents, especially in combination with an acid (like citric acid or tartaric acid). It releases carbon dioxide when combined with an acid and moisture, causing dough or batter to rise.
• Baked Goods: Used in the production of various baked products, such as cakes, cookies, and bread, to create light and fluffy textures.

Anticaking Agent

Sodium Carbonate prevents lumping in powdered or granulated foods, keeping them free flowing.

Sodium Carbonate for Industrial Applications, our Lohtragon® E11

Anhydrous Sodium Carbonate (CAS No. 497-19-8) plays an important role in several industrial applications, such as:

Concrete Accelerator

Lohtragon^® E11 | based on Sodium Carbonate, is used in concrete mixtures as a set accelerator. By promoting faster hydration of cement, it speeds up the setting and hardening process of concrete, which can be particularly beneficial in cold weather conditions where curing times are typically longer. This accelerant effect helps reduce the waiting time for concrete to reach sufficient strength, allowing for quicker construction progress. Additionally, the use of Sodium Carbonate, anhydrous can enhance early strength development in concrete, making it a useful additive in projects where rapid setting is essential.

Industrial Catalyst & Metal Refinement

Our Lohtragon^® E11, is a versatile fluxing agent used in metal oxide catalyst preparations. It aids in impurity removal, enhances product purity, and improves process efficiency, making it essential for industrial catalyst production and metal refining.

Glass & Ceramics Production

Sodium Carbonate, is a fluxing agent used in glass and ceramic production. It lowers the melting point of raw materials, enabling a homogeneous molten mixture at lower temperatures, improving energy efficiency and reducing costs.

Metallurgical Applications

In metallurgical processes, Lohtragon^® E11 helps to remove impurities from metal ores by enabling them to form slag, which can be easily separated. This fluxing action is crucial in enhancing the efficiency and quality of industrial chemical reactions.

Home & Cleaning Applications

Lohtragon^® E11, based on anhydrous Sodium Carbonate, is widely used in household care and cleaning products. It enhances the performance of detergents by softening water. In household cleaners, anhydrous Sodium Carbonate is used to break down grease, dirt and stains on various surfaces, making it a versatile component in multi-purpose cleaning products. It also acts as a pH adjuster, neutralizing acidic soils and improving the overall effectiveness of cleaning formulations.
